- product description
1. Natural rubber NR
It has good corrosion resistance to weak acids and alkalis, salts and chloride solutions, and has poor corrosion resistance to oils and solvents. It is not recommended for ozone media. Recommended working temperature: -57 ℃ ~ 93 ℃.
2. Neoprene CR
Neoprene is a synthetic rubber that is resistant to moderate corrosive acids, alkalis and salt solutions. Good corrosion resistance for commercial oils and fuels. However, its corrosion resistance is poor in strongly oxidizing acids, aromatic hydrocarbons and chlorinated hydrocarbons. Recommended working temperature -51 ℃ ~ 121 ℃.
Butadiene rubber is a synthetic rubber, suitable for a wide range of temperature with good resistance to oil, solvents, aromatic hydrocarbons, basic hydrocarbons, petroleum and natural gas corrosion performance. Good corrosion resistance to hydroxides, salts and near neutral acids. However, in strong oxidizing media, chlorinated hydrocarbons, ketones and lipids, their corrosion resistance is poor. The recommended operating temperature is 51 ° C to 121 ° C.
Fluorine rubber compound is made by mixing binary and ternary fluorine rubber with compounding agent and vulcanizing agent. In addition to excellent heat resistance, medium resistance, and good physical and mechanical properties, it also has low compression set, good elasticity and long service life. Fluorine rubber has outstanding heat resistance (200 ~ 250 ℃) and oil resistance. It can be used to make cylinder liner seals, rubber bowls and rotating lip seals, which can significantly improve the service life. Recommended working temperature: -40 ℃ ~ 232 ℃.
5． Silicone Rubber
Silicone rubber has outstanding resistance to high and low temperatures, and can be used at 150 ° C for a long time without change in performance; it can be continuously used for 10,000 hours at 200 ° C, and its unique use elasticity can be maintained in the working temperature range of -70 to 260 ° C. And ozone resistance, weather resistance and other advantages, suitable for the production of gaskets required in thermal institutions, such as sealing gaskets, valve gaskets, oil seals (suitable for aqueous media), etc., special silicone rubber can be used to make oil seals.
6. EPDM rubber
Good corrosion resistance to strong acids, strong bases, salts and chloride solutions. It does not apply to oils, solvents, aromatics and hydrocarbons. Recommended working temperature -57 ℃ ~ 176.
