TMA PT 1600

Vertical Thermomechanical Analyzer TMA PT1600


On point

The design of the TMA PT 1600 Thermomechanical Analyzer guarantees highest precision, reproducibility and accuracy. The system was constructed to performing 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.

Application example: Elastomer (non high temperature in this case)

Because of their very special and versatile properties, polyurethanes Elastomers have found wide application in virtually every industry, varying from the automotive, electrical and electronic industry, design and textile industry, to the mining and heavy duty industry.

Evaluation of Elastomers specifically developed for applications above 0°C. The glass point was detected at 29.9°C. When further increasing the temperature, additional expansion of the material in the elastic range occurs. The plastic range of the material has not been reached during this evaluation.

Determination of Young’s Modulus using Linseis TMA PT1600

The Linseis TMA PT 1600 can apply sinus shaped force programs to any sample. This enables the user to determine the bending and also Young’s Modulus of almost any material. Initially designed for mainly polymer applications, the Linseis TMA PT 1600 has recently been upgraded to be able to measure also harder materials such as metal alloys and pure metals, using force ranges up to 20 N by enlarging the possible sample size. In the application below a nickel sample of 8.4 mm length, 5.12 mm diameter and 0.2 mm thickness was measured using a static force of 500 mN and a fluctuating sinus shaped force of additional 1 N. The blue curve shows the movement of the sample as change in length that is caused by the force and the red curve shows the resulting E-modulus of this 3-point-bending experiment. The experiment was performed at 50 °C and is very close to literature data. One could also perform this at any temperature the instrument could achieve to be able to screen a larger range.

Difference in thermal expansion behavior of bricks depending on relative humidity

Humidity can have a huge influence on many materials, especially materials that are used for packaging or construction such as polymers, wood, bricks, concrete and many more. In the given application, two historical brick variants have been investigated and compared to contemporary, similar bricks regarding their expansion at different humidity levels. Therefore, the materials were first measured at linear expansion mode using a Linseis TMA PT 1600. The result was a straight forward linear expansion. Then the same experiment was repeated using a water vapor generator to simulate 35% relative humidity. The samples were kept at these conditions for 2 h and then the expansion coefficient was again determined vs temperature keeping the humidity level constant. The result shows a significant increase in linear expansion behavior due to swelling of the material. This effect will occur at any humidity level and should be considered carefully when calculating the expansion of such materials for any application.
