Polyethylene, or PE for short, is a thermoplastic resin made by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of alpha-olefin. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance (the lowest use temperature can reach -100 ~ -70 ° C, good chemical stability, can resist the erosion of most acids and bases, insoluble in general solvents at room temperature, small water absorption, excellent electrical insulation.1681721406229536.jpg

Acid and alkali-resistant timing belts are designed to withstand harsh chemical environments while maintaining their functionality and mechanical properties. They are often used in industries such as chemical processing, wastewater treatment, and food processing. Some excellent characteristics of acid and alkali-resistant timing belts include:

(1) Excellent aging resistance, weathering resistance, ozone resistance, sunlight resistance, heat resistance, water resistance, water vapor resistance, UV resistance, radiation resistance and other aging properties, when used with other unsaturated diene rubber such as NR, SBR, BR, NBR, and CR, it can play the role of polymer antioxidant or antioxidant.

 (2) Excellent chemical resistance, resistance to acids, alkalis, detergents, animal and vegetable oils, alcohols, ketones, etc.; outstanding resistance to water, superheated water, water vapor; resistance to polar oils.

 (3) Excellent insulation properties, volume resistivity 1016Q-cm, breakdown voltage 30-40MV/m, dielectric constant (1kHz, 20℃) 2.27.

 (4) Wide operating temperature range, low operating temperature -100~-70°C
