The rubber and plastic low temperature brittleness tester is used to measure the highest temperature of rubber and plastic samples when they are damaged by impact under specified conditions, that is, the brittle temperature. It can be used to compare the performance of non-rigid plastics and other elastic materials under low temperature conditions, and the advantages and disadvantages of temperature and low temperature performance.
