Its chain structure prevents orderly crystallization; the material therefore has no classic crystallinity like semi-crystalline polymers (e.g. <a href=\"https:\/\/www.linseis.com\/en\/applications\/polymers\/lfa-500-polyethylene-pe-thermal-diffusivity\/\"><strong>polyethylene<\/strong><\/a>). This amorphous structure is largely responsible for the exceptional optical clarity and homogeneity of the material (Lin et al., 2021). In this context, it should be noted that glass is also an amorphous material, which explains the high transparency of both materials and makes the term &#8220;acrylic glass&#8221; technically comprehensible. In mixtures with other polymers (e.g. <a href=\"https:\/\/www.linseis.com\/en\/wiki\/pvdf-polyvinylidene-fluoride-high-performance-polymers-for-pharmaceutical-and-medical-applications\/\"><strong>PVDF<\/strong><\/a>), the molecular weight gradient of PMMA influences the crystallization and microstructure of such blends. The coupling of glass transition, crystallization and molecular weight has been described in detail in recent studies and quantified using modern methods such as SAXS\/DSC.      <\/p><p>The almost completely amorphous structure of PMMA has a decisive influence on the mechanical and optical properties of the material. Due to its amorphous structure, PMMA is flexible, impact-resistant and malleable. It has no crystalline lamellae, which would make the material hard and brittle, as is the case with semi-crystalline polymers. The amorphous packing ensures even load distribution and therefore good mechanical damping and elongation at break. In comparison, crystalline polymers are often harder but significantly more brittle.    <\/p><p>The high optical purity and light transmission of PMMA results directly from its amorphous, regular structure. Crystalline areas would scatter light and cloud the material, as is usual with semi-crystalline plastics. This is why PMMA achieves a transparency of up to 92% &#8211; making it one of the most transparent plastics and predestined for optical applications. The lower the <a href=\"https:\/\/www.linseis.com\/en\/wiki\/what-happens-during-crystallization-tc\/\"><strong>crystallinity<\/strong><\/a>the better the optical properties and impact strength.   <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ac9afd3 elementor-widget elementor-widget-spacer\" data-id=\"ac9afd3\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-1b982d6 elementor-widget elementor-widget-heading\" data-id=\"1b982d6\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Glass transition temperature and thermal properties<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-a4a32ba elementor-widget elementor-widget-spacer\" data-id=\"a4a32ba\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-5df331d elementor-widget elementor-widget-text-editor\" data-id=\"5df331d\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>PMMA does not have a classic <a href=\"https:\/\/www.linseis.com\/en\/wiki\/melting-point-crystallization-and-glass-transition-in-polymers\/\"><strong>melting point<\/strong><\/a>but has a <a href=\"https:\/\/www.linseis.com\/en\/wiki\/glass-transition-temperature\/\"><strong>glass transition temperature (Tg)<\/strong><\/a>which, depending on the molecular weight and modification, is usually in the range of 85-105\u00b0C. Technically relevant PMMA grades reach Tg values of up to around 165\u00b0C, especially with targeted copolymerization or the addition of fillers. In blends, the glass transition shifts to higher temperatures as the molecular weight increases, which also influences the thermomechanical properties.  <\/p><p>The glass transition temperature is a key parameter for the thermal stability of PMMA. It describes the temperature range in which the amorphous polymer changes from a hard, glass-like to a soft, rubber-like state. If the temperature is below the Tg, the material remains dimensionally stable and retains its mechanical properties &#8211; which is why PMMA is also suitable as a thermally resistant material for many technical applications.  <\/p><p>As soon as the temperature exceeds the glass transition temperature, the mobility of the molecular chains increases considerably, which leads to a significant reduction in rigidity and dimensional stability. The material begins to &#8220;flow&#8221; and loses its mechanical integrity &#8211; thermal stability effectively only exists up to Tg. For long-term applications, even lower maximum application temperatures are usually recommended for safety reasons (approx. 75\u00b0C continuous use).  <\/p><p>Pure PMMA is heat resistant up to around 80\u00b0C; this value can be significantly increased through targeted copolymerization, filler integration or nano-reinforcement (Tg up to 122\u00b0C and degradation start &gt;340\u00b0C are possible). PMMA is therefore generally suitable for most ambient and low-heat applications, but is less suitable than glass for continuous use at high temperatures. The low thermal conductivity of PMMA can even be an advantage for temperature control in optical systems (Park et al., 2019).  <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-636a704 elementor-widget elementor-widget-spacer\" data-id=\"636a704\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3122b84 elementor-widget elementor-widget-heading\" data-id=\"3122b84\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Variants and copolymers - diversity of PMMA<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-bead9d0 elementor-widget elementor-widget-spacer\" data-id=\"bead9d0\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-e7813c8 elementor-widget elementor-widget-text-editor\" data-id=\"e7813c8\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>PMMA is available in numerous variants. In addition to homopolymers, there are various copolymers with other methacrylates (e.g. ethyl methacrylate, isobornyl methacrylate) and functional groups that specifically modify optical, thermal and mechanical properties. Copolymers with hydrophobic, UV-stabilizing or high-temperature stable components are particularly relevant for technical and decorative applications. One example is PMMA\/IBMA (isobornyl methacrylate) for optical fibers with increased heat resistance (Zaremba et al., 2017).   <\/p><p>The various types and copolymers of PMMA differ significantly in terms of their chemical, UV and mechanical resistance thanks to specific modifications. <strong>Homopolymer PMMA<\/strong> offers very good optical clarity and high weather resistance. It is resistant to diluted acids and alkalis, aliphates and many chemicals. However, its impact strength is limited and special requirements such as UV stability or flexibility can only be met to a limited extent.  <\/p><p><b>Impact-modified PMMA grades<\/b> have significantly higher fracture and crack resistance thanks to the addition of modifiers (e.g. acrylonitrile-butadiene-styrene, rubber). Despite improved mechanics, they retain excellent optical properties and weather resistance &#8211; ideal for applications with high impact loads and safety requirements. <\/p><p><b>UV-stabilized PMMA grades<\/b> contain UV absorbers or stabilizers, which drastically increase long-term outdoor durability and resistance to yellowing. These grades are particularly suitable for outdoor structural and optical applications. <\/p><p><b>PMMA copolymers<\/b> &#8211; for example with ethyl acrylate or butyl acrylate &#8211; are softer and more flexible than the homopolymer and have improved impact resistance and more dimensionally stable properties under changing environmental conditions. They show higher chemical resistance to bases as well as better hydrolysis and oxidation resistance compared to the homopolymer. <\/p><p>PMMA is available as an extruded product, cast product, impact-modified grades, blends and copolymers as well as colored and light-diffusing variants. Impact-resistant grades are suitable for protective glazing and machine protection, while high-purity grades are used in optics (lenses, light guides). <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-b097936 elementor-widget elementor-widget-spacer\" data-id=\"b097936\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-95aac46 elementor-widget elementor-widget-heading\" data-id=\"95aac46\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Chemical, UV and mechanical resistance<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6dd2e47 elementor-widget elementor-widget-spacer\" data-id=\"6dd2e47\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-a18f69c elementor-widget elementor-widget-text-editor\" data-id=\"a18f69c\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>PMMA is very resistant to UV rays &#8211; the material yellows and ages significantly less than other plastics, which in turn is due to the dense packing of the amorphous chains (SpecialChem, 2024). Acrylic glass exhibits exceptional weather resistance, remaining transparent and dimensionally stable even after years of outdoor exposure, which often surpasses glass. Chemically, PMMA is resistant to many acids and bases as well as water &#8211; however, organic solvents can attack it.  <\/p><p>Mechanically, PMMA impresses with its high impact strength and fracture resistance: the impact strength is up to ten times higher than that of glass, which is particularly relevant in safety-critical applications. Modification with nanoparticles (e.g. ZrO\u2082, ZnO, CeO\u2082) can significantly improve UV resistance and thermal stability. Nano-reinforced PMMA composites reach thermal decomposition temperatures of up to 368\u00b0C and almost completely block UV rays up to 360nm.  <\/p><p>The durability of PMMA makes it an ideal material for long-term applications. While other plastics degrade quickly when exposed to UV light, PMMA retains its original properties for years. This stability is particularly important for outdoor applications such as fa\u00e7ade glazing, greenhouses or automotive components.  <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-a6b66bf elementor-widget elementor-widget-spacer\" data-id=\"a6b66bf\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-1443f70 elementor-widget elementor-widget-heading\" data-id=\"1443f70\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Typical applications and areas of use<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ac47d19 elementor-widget elementor-widget-spacer\" data-id=\"ac47d19\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-7a2ebce elementor-widget elementor-widget-text-editor\" data-id=\"7a2ebce\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>The versatile properties of PMMA open up a wide range of possible applications.

The light transmission of PMMA reaches up to 92% of visible light and is therefore higher than that of conventional float glass. Haze is less than 1% and UV transmission can be up to 73%, which is particularly important for applications in microfluidics, optical systems and AR applications.  <\/p><p>At the same time, it should be noted that glass still has advantages in certain areas of application. Especially at high continuous temperatures and in highly chemically stressed environments, glass is superior due to its higher temperature stability and its almost universal chemical resistance. The choice of material is therefore always made on an application-specific basis and in consideration of optical, mechanical and thermal requirements.  <\/p><p><b>Weight and safety<\/b> also speak in favor of PMMA: the material is only about half as heavy as glass and never shatters &#8211; an important safety aspect for facades, vehicles and appliances. In the event of damage, there are no sharp-edged fragments that could cause injury. <\/p><p>The <b>moldability of PMMA<\/b> is another decisive advantage. PMMA can be thermally bent and precisely injection molded at 130\u00b0C &#8211; temperatures of over 600\u00b0C are required for glass. This makes it much easier to produce complex and large shapes while maintaining surface quality and optical purity.  <\/p><p>The <b>design freedom<\/b> makes it possible to flexibly adjust the color, transparency, surface structure and optical properties &#8211; ideal for lighting and design. PMMA can be colored, textured or given special optical effects without losing its basic properties. <\/p><p>The <b>long-term durability<\/b> of PMMA surpasses that of glass in many areas. In contrast to glass, PMMA remains permanently chemically and mechanically stable, resists UV light and only ages slightly. While glass can corrode or discolor under certain environmental conditions, PMMA retains its properties for decades.  <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-9a9a970 elementor-widget elementor-widget-spacer\" data-id=\"9a9a970\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-d9a9969 elementor-widget elementor-widget-heading\" data-id=\"d9a9969\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Scientific perspectives and current research<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-559cc27 elementor-widget elementor-widget-spacer\" data-id=\"559cc27\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4f7136e elementor-widget elementor-widget-text-editor\" data-id=\"4f7136e\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>PMMA is the subject of numerous research projects on compound modifications, blends and nanocomposites, in particular to further improve thermal stability, UV resistance and mechanical performance.
