1、 Overview
The XCY type single test vulcanized rubber brittleness temperature tester is used to measure the high temperature at which the vulcanized rubber sample shows failure after being impacted under specified conditions. It is the brittle temperature. Comparative evaluation of the performance of non rigid plastics and other materials under low temperature conditions can be conducted.

2、 Technical parameters
