Rubber Low Temperature Brittleness Tester TRBT-A11

Rubber low temperature brittleness tester TRBT-A11 is specialised to study the effects of low temperature on rubber. This is achieved when vulcanized rubber is exposed to damage via an impact from test conditions; which is therefore called as brittle temperature. It identifies the difference between non-rigid plastic on exposure to low temperature. Flexible in evaluating low temperature performance quality of different types of vulcanized rubber materials which is essential in production process.
