Product Description
BPTW Series Brittleness Temperature Tester | Low Temperature Testing Bath for Plastics is a compressor refrigeration instrument developed by BuenoBiotech according to the requirements for GB1682 national standard. The maximum temperature at which the sample is damaged by impact under the specified conditions, that is, the brittleness temperature, can be used to comparatively evaluate the performance of plastics and other elastic materials under low temperature conditions. The brittle temperature and low temperature properties of vulcanized rubbers of different rubber materials or different formulations can be determined. Therefore, it is indispensable in the quality inspection of scientific research materials and their products, and the control of production processes. The instrument is designed according to GB1682 national standard, and the technical indicators meet the requirements of HG 2-162-1965 plastic low temperature impact compression test method and GB5470-2008 plastic impact embrittlement temperature test method.
Product Features
1. Adopt imported compressor, cascade refrigeration technology, large cooling capacity, fast cooling.
2. High precision temperature control system adopts PID temperature control technology, precision can reach 0.5 ℃.
3. Super stainless steel low-temperature box: 150×150×240 mm, can hold 60 ~ 120 samples.
4. Stainless steel liner corrosion resistanc, with three sample baskets.
5. Beautiful and exquisite appearance design, simple and convenient operation.
6. Metal shell durable, side into the wind, side exhaust, good heat dissipation performance.
7. With casters, it is more convenient to move.
Application
BPTW Series Brittleness Temperature Tester | Low Temperature Testing Bath for Plastics can measure the brittleness temperature and low temperature performance of vulcanized rubber of different rubber and plastic materials or different formulations, so it is indispensable in the quality inspection of scientific research materials and their products, and control in production process.
