Temperature Retraction Testers measures the effects of low temperature on rubber, plastic and other elastomeric materials. It allows the accurate evaluation of crystallization and the comparison of rubber and rubber-like sample viscosity at low temperatures. It stretches a sample and allows it to react. It allows retraction point calculation and comparison and readings are presented real-time and saved. It also details a sample percentage of retraction at different temperatures and allows the determination of a temperature range in which a sample is elastic. It is used with a Benz BPT 2100, a high accuracy brittle point tester for low temperature use. It provides highly accurate controlled temperatures and reduces operator intervention.
