Rubber Low-temperature Brittleness Tester

The machine can used for plastic low-temperature test.(According to customer’s requirement,can meet the standard GB/T 15256-2014 “vulcanized rubber or thermoplastic rubber low temperature brittleness multiple-sample method” and GB/T 1682-94 “vulcanized rubber low temperature brittleness single sample method”

Product Details Attachment Accessories

Uses and features:
The rubber low-temperature brittleness tester is determined the highest temperature when the sample is damaged by the impact of the vulcanized rubber under the specified conditions, that is, the brittleness temperature, and the performance of the non-hard plastic and other elastic materials under low temperature conditions can be comparatively identified. It can measure the brittleness temperature and low temperature performance of vulcanized rubber of different rubber materials or different formulations. Therefore, it is indispensable in the quality inspection of scientific research materials and their products, and the control of production processes. This instrument is designed according to GB/T5470-2008 <plastic impact embrittlement temperature test method>, GB/T 15256-2014 <Vulcanized rubber low temperature brittleness measurement (multi-sample method)> national standard design, the latest development of compressor refrigeration equipment. The equipment adopts the cascade compressor refrigeration technology, and uses the principle of heat balance and the circulating stirring method to achieve automatic uniform cooling and constant temperature of the sample, which can fully meet the various temperature control indexes stipulated by the national standard GB/T229-94.
