Rubber gaskets cut from the industrial rubber sheets Silicone EPDM VTION NBR ect which is produced by FEITE sealing sheets.
DESCRIPTION: FEITESEAL G163 Rubber Gasket
The main products of rubber gaskets are silicone gasket, nitrile-butadiene rubber gasket (NBR), fluorine rubber gasket (VITON) and others. Silicone rubber has outstanding resistance to high and low temperature, and it can remain good flexibility at -70°C~+260°C temperature range. It is ozone-resistant, resistance to weather aging, and can be gasket in hot machines. Silicone rubber is nontoxic and can be made of insulation products and medical rubber products. Also it has waterproof, flame retardant, high-temperature resistance, conductive, abrasion resistance, oil resistance and other excellent performance. It is widely used in machinery, electronics, hot-water heating and other industries. Our silicone rubber gasket products all comply with EU environmental standards and EU food standard.
Nitrile-Butadiene rubber is a emulsion polymer of butadiene and acrylonitrile. It is known for excellent oil resistance, but also has good abrasion resistance, aging resistance and gas confidentiality. It is widely used in rubber industry
Fluorine rubber has a high temperature resistance, can be used at -20°C~+200°Cenvironments. It is resistant to strong oxidizing agent, oil, acid and alkali and commonly used in high temperature, high vacuum and high pressure environment, and also suitable for oil environment. It is widely used in petroleum, chemical industry, aviation, aerospace and other departments.
Neoprene, natural rubber, EPDM rubber, acrylic plastic and other special rubbers all has high resistance to oil, acid and alkali and with abrasion resistance, high and low temperature resistance and other characteristics.
Rubber gasket like NBR, SBR, CR, EPDM all with resistance to oil, acid, cold and heat, and anti-aging properties, can be directly cut into various shapes of sealing gasket. They are widely used in medicine, electronics, chemicals, antistatic, flame retardant, food and other industries.

The sheet-shaped rubber products which are in the metal flange or other connecting parts between two stationary surfaces playing the role of sealing are all called rubber gasket. It is manufactured by molding or vulcanized film punching. It is widely used in various mechanical equipment, sealing and buffering.
