Thermo mechanical analysis (TMA) easily and rapidly measures sample displacement (growth, shrinkage, movement, etc.) as a function of temperature, time, and applied force. Traditionally, TMA is used to characterize linear expansion, glass transitions, and softening points of materials by applying a constant force to a specimen while varying temperature. For expansion measurements, a probe rests on a sample on a stage with minimal downward pressure. Other constant force experiments include measurement of penetration, bending, tension, shrinkage, swelling, and creep (sample motion measured as a...

Sample Holders Sample Chamber A broad range of sample holders is available for the TMA. Hence the best method for testing can be selected for every application. Furthermore LINSEIS can certainly provide aid for special customer requirements. The easily accessible chamber is located in the center of the furnace. Both temperature and atmosphere can be controlled. In addition an optional mass flow controller is available for purge gas regulation. The gas tight cell can be evacuated and allows you to measure under a defined atmosphere. Only such a system can provide definitive information concerning...

1. Elastomers 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. 2. Polyvinylchloride...

Delta-L(2)[BK-00-4] DTA Signal [BK-00-3] Base Line [BK-00-3] 4. DTA - Feature The thermal expansion of rock crystal ( -SiO2) can be easily evaluated with the L75 Dilatometer. The additional DTA feature enables an in depth view of the thermal behavior of the material. The DTA measurement is a mathematical routine based on the sample temperature. Exo- and endothermic effects influence the change of the sample temperature during the dynamic heating or cooling cycle. At app. 575°C the phase transition from - to -SiO2 takes place. The deviation of the measured temperature from the literature value...
