Brittleness Temperature Tester is intended to measure the brittleness temperature of vulcanized rubber, which is the lowest temperature at
which none of a set of specimens fractures due to low-temperature embrittlement when tested under the specified conditions.
The low-temperature brittleness tester can be used to make comparative identification of functional performance for the non-rigid plastic and other elastic materials under the low-temperature condition and measure the pros and cons of low-temperature properties of different rubber materials and compound rubbers with different formulas. Therefore, the brittleness temperature tester is one of the vital rubber instruments in the quality inspection of scientific research and controlling the production process.

This testing machine comprises a refrigeration system, temperature control device, temperature-measuring device, heat-transfer medium,
cooling bath, automatic alarm device, etc. After turning on the refrigerating switch, the compressor starts working to enter into the refrigerating state. When it is close to the set temperature, the heating device in the cooling tank starts to provide heat in proportion to balance the excess cold produced by the refrigeration system to achieve the purpose of constant temperature. Stirring can continuously circulate the cooling medium in the cooling bath to ensure the uniformity of temperature.
