HT-4068 Rubber Plastic Low Temperature Brittleness Tester

The low temperature brittleness tester for rubber and plastic adopts compressor refrigeration. It is used to measure the highest temperature when the sample is damaged by impact under specified conditions, that is, the brittle temperature. It can make comparative identification of the performance of plastics and other elastic materials under low temperature conditions. It can measure the brittle temperature and low temperature performance of different rubber materials or vulcanized rubber with different formulas. Therefore, it is indispensable in scientific research materials and product quality inspection, production process control and other aspects. This machine meets the requirements of GB/T 1682, GB/T15256 ,GB/T5470, ISO 812,ASTM D3418,ASTM D2137,ISO 974,ASTM D746,ASTM D1790 and with novel design, unique structure, advanced technology, stable performance and high automation level.

Technical parameters:

1. Test temperature and time: -70 degrees (normally more than 1 hour) cooling time is short, no water cooling is required, more environmentally friendly;

2. Cooling speed: 0℃ ~ -30℃ 1.2℃/min

-30℃ ~ -40℃ 1℃/min

-40℃ ~ -70℃ 0.7℃/min;

3. Impact speed: 2m/s±0.2m/s;

4. After constant temperature, temperature fluctuation <±0.5℃, small fluctuation, more accurate temperature control;

5. Distance from the center of the impactor to the lower end of the clamp: 11±0.5mm;

6. Maximum dimensions: 900×505×950mm (length×height×width);

7. Effective space of the studio: 160×140×100mm (length×height×width);

8. Power: 800W, the power is smaller, and the compressor will automatically stop after reaching the temperature, which is more environmentally friendly and energy-saving.
