Related Products And Applications Of Rubber Gaskets

Rubber gaskets are sheet-shaped rubber products that seal between two stationary surfaces of metal flanges or other connecting parts, collectively referred to as rubber gaskets. It can be manufactured by the molding method, and can also be processed by the vulcanized film. It can be widely used in all kinds of mechanical equipment, playing the role of lining, sealing, buffering, and so on.

In terms of form, commonly used rubber gaskets include: rubber flat gaskets, rubber O-rings, plastic flat gaskets, PTFE-covered gaskets, asbestos rubber gaskets, metal flat gaskets, metal special-shaped gaskets, metal-sheathed gaskets, wave gaskets, Wound washers, etc.

1. Rubber flat washer: easy to deform, easy to press, but poor pressure and temperature resistance, only used in places with low pressure and low temperature. The natural rubber has a certain acid and alkali resistance, and the operating temperature should not exceed 60 °C; neoprene rubber is also resistant to some acids and alkalis, and the operating temperature is 80 °C; nitrile rubber is oil-resistant and can be used up to 80 °C; Fluorine rubber has good corrosion resistance and is resistant to The temperature performance is also stronger than that of general rubber, and it can be used in a medium of 150 °C.

2. Rubber sealing washer: The cross-sectional shape is a perfect circle, and it has a certain self-tightening effect. The sealing effect is better than that of the flat washer, and the pressing force is smaller.

In terms of material, the main products of rubber pads are silicone pads, nitrile rubber pads, fluororubber pads, and other rubber pads. Rubber gaskets have the properties of oil resistance, acid and alkali resistance, cold and heat resistance, aging resistance, etc., and can be directly cut into various shapes of sealing gaskets, which are widely used in medicine, electronics, chemical industry, antistatic, flame retardant, food, and other industries.

Silicone Rubber

It has outstanding high and low-temperature resistance, maintains good elasticity in the temperature range of -70°C to +260°C, is resistant to ozone and weathering, and is suitable for sealing gaskets in thermal machinery. It is non-toxic and can be used to make thermal insulation, insulation products, and medical rubber products. At the same time, it has excellent properties such as waterproof, flame retardant, high-temperature resistance, electrical conductivity, wear resistance, oil resistance, etc. It is widely used in machinery, electronics, plumbing, and other industries.

Nitrile rubber

NBR (Nitrile-Butadiene Rubber) is a polymer formed by emulsion copolymerization of butadiene and acrylonitrile. It is famous for its excellent oil resistance, as well as good wear resistance, aging resistance, and airtightness. Therefore, it is widely used in the rubber industry.

fluororubber

It has high-temperature resistance, can be used in an environment of -20℃-+200℃, and is resistant to strong oxidants, oil, acid, and alkali. Usually used in high temperature, high vacuum, and high-pressure environments, but also suitable for oil environment, widely used in petroleum, chemical, aviation, aerospace, and other departments.

other

Neoprene, natural rubber, EPDM, acrylate, and other specialty rubbers. It has the characteristics of oil, acid, alkali, wear resistance, and high and low-temperature resistance.
