Thermomechanical Analysis

• Highest Resolution Thermo mechanical analysis (TMA) easily and rapidly measures sample allows to measure smallest nanometer changes displacement (growth, shrinkage, movement, etc.) as a function of tem- perature, time, and applied force. Traditionally, TMA is used to characte- measures weak transitions and elasticity rize linear expansion, glass transitions, and softening points of materials • Wide measuring range 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...

Technical Specifications The concept Sample chamber 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 the samples sensitivity to oxidation. Furnace The TMA Platinum Series comes with a robust and reliable furnace. Its customized design enables rapid heat up and cool down times and an excellent...

Because of their very special and versatile properties, polyurethanes Elastomers have found wide application in virtually every industry, va- rying 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 This plastic has found extensive use as an electrical...

DTA - Feature The thermal expansion of rock crystal (α-SiO2) can be easily evalu- ated with the L75 Dilatometer. The additional DTA feature enables DTA Signal (smoothed) [BK-00-3] 40 Base Line [BK-00-3] 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 α- to β-SiO2 takes place. The deviation of the measured temperature from the literature value (574°C)...
