Rubber Low Temperature Brittleness Tester HZ-7004B -70℃--20℃ Test Temperature 2m/S ±0.2m/S Impact Speed
Brittleness Tester Overview of Equipment
HZ-7004 touch screen vulcanized rubber low temperature brittleness tester is to determine the highest temperature, that is, brittle temperature, when the vulcanized rubber specimen is damaged by impact under specified conditions. The performance of non-rigid plastics and other elastic materials under low temperature conditions can be compared. The brittleness temperature and low temperature properties of different rubber materials or formulations can be measured. Therefore, it is necessary to examine the quality of materials and their products and control the production process.

Brittleness Tester Test Standard
Standards
ISO 812
ASTM D2137
GBT 5470 / 2008
The instrument is designed according to the national standard for the determination of embrittlement temperature of GBT 5470 / 2008 plastic impact method, ASTM D2137/ ISO 812Rubber vulcanized or thermoplastic-Determination low temperature brittleness can be customized The technical specifications meet the requirements of the national standard.
Brittleness Tester Device Principles
The equipment pushes the specimen into the freezing medium through the main cylinder driving holder, and after holding it for a certain time, lift the holder, then the secondary cylinder controls the impact process, observes the damage degree of the sample, and passes the repeated test. The minimum temperature of at least two samples without failure and the maximum temperature of at least one sample are determined. If the difference between the two results is not greater than 1 ℃, the test is finished.
