Rubber low temperature brittleness testing machine
Product Details
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.
This equipment adopts cascade compressor refrigeration technology, uses the principle of heat balance and circulating stirring method to achieve automatic uniform cooling and constant temperature of the sample.
