JZ-6043 Model Rubber-Plastic Low Temperature Brittleness TesterThe temperature at which a material specimen undergoes fracture under specified conditions due to impact is known as the brittle temperature. This allows for comparative evaluation of the usage performance of plastics and other elastic materials under low-temperature conditions. Therefore, it is indispensable in scientific research, quality inspection of materials and their products, and control of the production process. This instrument is designed in accordance with the national standards such as GB/T5470-2008, the Plastic Impact Brittle Temperature Test Method. In the existing design, a cold well stirrer has been added to ensure more uniform temperature distribution around the container, faster cooling, time-saving, and reduced energy consumption.

Rubber and Plastic Low Temperature Brittleness TesterThe temperature at which a specimen fails under impact under specified conditions is known as the brittle temperature. It is indispensable in scientific research, material testing, and process control. The low-temperature brittle tester conforms to multiple national standards, utilizing a cascade compression refrigeration system, which, through the principle of thermal equilibrium and cyclic stirring, achieves automatic and uniform cooling and constant temperature for the specimen.
