Rubber and plastic low-temperature brittleness tester

The single sample vulcanized rubber low-temperature brittleness tester is used to measure the maximum temperature at which the vulcanized rubber sample undergoes impact damage under specified conditions, which is called the brittleness temperature. It can be used for comparative evaluation of the service performance of non rigid plastics and other elastic materials under low temperature conditions. The brittleness temperature and low-temperature performance of vulcanized rubber with different rubber materials or formulations can be measured. Therefore, whether in scientific research materials and products quality inspection, production process control, and other aspects are indispensable.

Purpose of the equipment:

Rubber and plastic low-temperature brittleness tester can measure the brittleness temperature and low-temperature performance of different rubber materials or different formulations of vulcanized rubber. Therefore, whether in scientific research materials and products quality inspection, production process control, and other aspects are indispensable.

Industry Applied:

Rubber industry

Equipment characteristics:

This equipment uses the main cylinder to push the holder to extend the sample into the freezing medium and hold it for a certain time before lifting the holder. Then, the auxiliary cylinder controls the impact process, observes the degree of damage to the sample, and through repeated tests, determines the minimum temperature when at least two samples are not damaged and the maximum temperature when at least one sample is damaged. If the difference between the two results is not greater than 1 ℃, the test is completed.

Structural composition:

This equipment consists of a workbench, a lifting clamp, an impact device, a low-temperature thermometer, a cold well containing refrigerant, a compressor, and other parts.
