low temperature brittleness tester Measure the maximum temperature of vulcanized rubber when the sample is damaged by impact under specified conditions, which is the brittle temperature. It can make a comparative identification of the performance of plastics and other elastic materials under low temperature conditions. It can determine the pros and cons of brittleness temperature and low temperature performance of vulcanized rubber with different rubber materials or different formulations. Therefore, it is indispensable both in the quality inspection of scientific research materials, and in the control of the production process.
