Rubber antiskid gasket rubber and plastic products with sealing effect between two stationary surfaces of metal flange or other connection positions are generally called rubber gasket. It can be manufactured by die pressing method and cold extrusion with vulcanized rubber film. Can be widely used in a variety of industrial equipment, gasket, sealing, buffer effect.

In terms of mode, the common rubber gasket seal ring includes: vulcanized rubber flat washer, vulcanized rubber O-ring, plastic flat washer, polytetrafluoroethylene wrapped seal ring, stone wool rubber gasket, metal material flat washer, metal material special-shaped seal ring, metal material clad washer, corrugated seal ring, coil seal ring, etc.

(1) Vulcanized rubber flat washer: deformation is very easy, clamping is not hard, but the compression resistance and high temperature resistance are weak, only used in areas with low working pressure and low temperature. Natural rubber has certain corrosion resistance characteristics, and the application temperature is not suitable to exceed 60 ℃; chloroprene rubber can also withstand some strong acids and alkali, with the application temperature of 80 ℃; nitrile rubber is resistant to acid and alkali, and can be used up to 80 ℃; fluorine rubber has very good corrosion resistance and heat resistance than ordinary vulcanized rubber, and can be used in materials at 150 ℃.

(2) Vulcanized rubber gasket: the cross section is round, with certain self tightening effect. The actual sealing effect is better than that of flat washer, and the clamping force is smaller.

From the material point of view, the key products of rubber plate are: silica gel pad, nitrile rubber pad, fluororubber pad, other rubber plate. Rubber gaskets have the characteristics of acid and alkali resistance, corrosion resistance, low temperature resistance and aging resistance. They can be cut into various shapes of sealing washers immediately. They are widely used in pharmaceutical, electronic devices, chemical plants, antistatic, flame retardancy, food and other manufacturing industries.

silica gel

It has outstanding high and low temperature resistance test characteristics, stable application ductility in the temperature range of - 70 ℃ - + 260 ℃. It is resistant to active oxygen and weather embrittlement. It is suitable for sealing gasket in thermal mechanical equipment. Non toxic, it can be used to make heat insulation, insulating layer handicrafts and medical equipment rubber and plastic products. In addition, it has moisture-proof, flame retardant, heat-resistant, conductive, wear-resistant, acid and alkali resistance and other high-quality characteristics, widely used in mechanical equipment, electronic devices, plumbing installation and other manufacturing industries.

Nitrile rubber

NBR (Nitrile-ButadieneRubber) is a high polymer made of butadiene and acrylonitrile mixed with moisturizing emulsion. It is famous for its excellent wear resistance, and also has excellent wear resistance, anti-aging and sealing properties. Therefore, it is widely used in the production of vulcanized rubber.

Fluorine glue

It has heat resistance and can be used in natural environment from - 20 ℃ - + 200 ℃. It is resistant to oxidant, acid and alkali, and corrosion. It is generally used in high temperature, high vacuum pump and high pressure natural environment, and also suitable for the natural environment of raw oil. It is widely used in crude oil, chemical plants, airlines, aerospace and other units.

other

Chloroprene rubber, [1] natural rubber, ethylene propylene diene monomer, acrylate rubber and other special rubber. With acid and alkali resistance, acid, alkali, wear resistance, high temperature, ultra-low temperature and other characteristics.
