The Low-temperature Brittleness Tester evaluates the low-temperature resistance and brittle failure performance of rubber, plastic, elastomer, and polymer materials. It simulates extreme low-temperature working environments to test the critical temperature at which materials crack or break under impact load.
Featuring a high-efficiency refrigeration system and precise constant-temperature control technology, this machine offers fast cooling speed, uniform temperature field, and stable test results. It supports multi-sample batch testing with automatic impact and judgment functions, ensuring simple operation, high repeatability, and accurate data.
This equipment is used to compare and identify the functional performance of non-rigid plastics and other elastic materials under low-temperature conditions. It measures the advantages and disadvantages of low-temperature performance for different rubber materials and composite rubber formulations.
