TMA PT1600 (TMA Thermo Mechanical Analysis)

 The design of the TMA PT1600 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.

 Software:

All LINSEIS thermo analytical instruments are PC controlled. The individual software modules exclusively run under Microsoft® Windows® operating systems. The complete software consists of 3 modules: temperature control, data acquisition and data evaluation. The 32 bit software incorporates all essential features for measurement preparation, execution, and evaluation of a Thermogravimetric measurement. Thanks to our specialists and application experts, LINSEIS was able to develop comprehensive easy to understand user friendly application software.

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.
