TMA PT 1000
Thermomechanical Analyzer TMA PT1000
Description
On point
The design of the LINSEIS TMA PT1000 Thermomechanical Analyzer guarantees highest precision, reproducibility and accuracy. The system was constructed to perform a variety of Thermomechanical experiments on an array of sample shapes and sizes over a wide temperature range to meet all TMA needs. The system can perform either static or dynamic measurements due to a built in force/frequency generator.
Typical materials under investigation are: composite materials, glass, polymers, ceramics and metals. The variety of measuring systems allows sample geometries such as fibers, rods, films, rods or cylinders.

Applications
Application example: Polycarbonate (PC)
An important limiting factor for thermoplastic applications is the glass transition point. With the different loads on the polycarbonate molded parts investigated here, the TMA shows that softening occurs long before the glass transition temperature is reaches. During this investigation the material has been penetrated by a pushrod with two different forces (1cN and 2cN). Depending on the load, the depths of the penetrations have varied. The heating rate for both evaluations has been 5K/min.
