Product Information

PUMP rubber gasket has good corrosion resistance and is resistant to seawater, grease, acid, alkali and other chemicals. At the same time, it is also antibacterial, non-toxic, tasteless and pollution-free. The gasket has good elasticity, abrasion resistance and air tightness, and is harmless to human body. The rubber gasket has water resistance, and the closed bubble structure can prevent water absorption and moisture. It is easy for hot pressing, cutting, gluing, fitting and other processing.

Non-metallic gasket material

1. Natural rubber NR

It has good corrosion resistance to weak acid and alkali, salt and chloride solution, but poor corrosion resistance to oil and solvent, so it is not recommended to be used in ozone medium. The recommended operating temperature is -57 ° C to 93 ° C.

2. Neoprene CR

Neoprene is a synthetic rubber that is resistant to moderately corrosive acid, alkali and salt solutions. Good corrosion resistance to commercial oils and fuels. However, the corrosion resistance of strong oxidizing acids, aromatic hydrocarbons and chlorinated hydrocarbons is poor. Recommended operating temperature -51 ° C to 121 ° C.

3. Butadiene rubber NBR

Cyanobutadiene rubber is a synthetic rubber suitable for a wide temperature range with good corrosion resistance to oils, solvents, aromatic hydrocarbons, basic hydrocarbons, petroleum and natural gas. It has good corrosion resistance to hydroxides, salts and near neutral acids. However, its corrosion resistance is poor in strong oxidizing media, chlorinated hydrocarbons, ketones and lipids, and the recommended operating temperature is 51℃~121℃.
