4. Fluorine rubber gasket FKM rubber gasket, FPM fluorine rubber sheet, VITION fluorine rubber gasket, 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 manufacture cylinders according to the standards HG/T20606-1997, HG20606-2009, HG20627-1997, HG20627-2009
GB/T9126-2003 Application: hot oil, aromatic solvent, chemicals, vegetable oil and grease, natural gas, fuel, ozone, steam, hot water, air, dilute acid, etc. The recommended working temperature is -40℃~232℃.
5. Silicone Rubber Gasket Silicone rubber has outstanding resistance to high and low temperature, and can be used for a long time at 150°C without performance changes; it can be used continuously for 10,000 hours at 200°C, and can maintain its performance in the operating temperature range of -70 to 210°C. It has the unique advantages of flexibility, ozone resistance, weather resistance, etc., suitable for making gaskets required in thermal mechanisms, such as gaskets, valve gaskets, oil seals (applicable to water media), etc. Special silicone rubber can be used to make oil seals. Executive standard HG/T20606-1997, HG20606-2009, HG20627-1997, HG20627-2009
GB/T9126-2003 Application: Hot air, oxygen, water, machinery and transmission oil, animal and vegetable oil and lubricating grease, non-petroleum brake oil, fire-resistant hydraulic fluid, diluted hydrochloric acid solution, ozone, etc.
6. EPDM rubber gasket has good corrosion resistance to acid, alkali, salt and chloride solution. But it does not apply to oils, solvents, aromatic hydrocarbons and hydrocarbons. The recommended working temperature is -57℃~150. Executive standard HG/T20606-1997, HG20606-2009, HG20627-1997, HG20627-2009GB/T9126-2003 Application: water, alcohol, glycol, ketone, silicone oil and grease, weak acid, etc.
