Rubber and Plastic Low Temperature Brittleness Tester
Product Introduction
The MZ-4068B1 Rubber and Plastic Low Temperature Brittleness Tester is used to measure the highest temperature at which a vulcanized rubber specimen undergoes damage after being impacted under specified conditions, which is known as the brittleness temperature. This machine can perform single sample testing, which is carried out by lifting the cylinder, impacting with a spring, and cooling with an alcohol compressor. Meet the spring technical requirements of GB/T 1682-2014 "Determination of low-temperature brittleness of vulcanized rubber - Single specimen method".
