The Application Of Rubber Gasket
Aug 08, 2017


Rubber gasket:

   Rubber gasket with oil, acid, cold and heat,  anti-aging properties, can be directly cut into various shapes of gaskets,  widely used in medicine, electronics, chemicals, anti-static, fire-retardant,  food and other industries.

Related products and applications:

    Rubber gasket in the metal flange or other  connection between the two stationary surfaces of the seal between the  sheet-shaped rubber products known as rubber gasket. Can be made by molding, vulcanized film can also be  used. Can be widely used in a variety of  machinery and equipment, from the pad, sealing, cushioning and so  on.


  In addition, the commonly used rubber washers  arehers: rubber flat washers, rubber O-rings, plastic flat washers,  polytetrafluoroethylene gaskets, asbestos rubber washers, metal flat washers,  metal shaped washers, metal washers, Winding washers and so on.


(1) rubber flat washers: easy deformation, pressure  when the effort, but the pressure, temperature resistance are poor, only for low  pressure, the temperature is not high place. Natural rubber has a certain acid and alkali  resistance, the use of temperature should not exceed 60 ℃; chloroprene rubber  can also resistance to some acid and alkali, the use of temperature 80 ℃;  nitrile rubber oil, available to 80 ℃; fluorine rubber corrosion resistance is  very good Temperature performance is  also stronger than the general rubber, can be used in the 150 ℃  medium.

(2) rubber sealing  gasket: cross-section shape is round, there is a certain self-tightening effect,  the sealing effect is better than the flat washer, the clamping force is  smaller.

   From the material  point of view, the main products are rubber pad: silicone pad, nitrile rubber  pad, fluorine rubber pad, other rubber pads. Rubber gasket with oil, acid, cold and heat,  anti-aging properties, can be directly cut into various shapes of gaskets,  widely used in medicine, electronics, chemicals, anti-static, fire-retardant,  food and other industries.

Silicone Rubber:

Has a high resistance to high and low temperature  performance, in the -70 ℃ - +260 ℃ temperature range to maintain good use of  elasticity, ozone resistance, weather resistance, should be used in the  thermomechanical seal gasket. Non-toxic  can produce insulation, insulation products and medical rubber products.  At the same time with waterproof, flame  retardant, high temperature, conductive, wear, oil and other excellent  performance, widely used in machinery, electronics, plumbing and other  industries.

Nitrile  rubber:

NBR (Nitrile-Butadiene  Rubber) is a polymer made of butadiene and acrylonitrile by emulsion  copolymerization, and its excellent oil resistance is known, but also has good  wear resistance, aging resistance and air tightness. And thus widely used in the rubber  industry.


fluororubber:

With high temperature resistance, can be -20 ℃ -  +200 ℃ environment, resistant to strong oxidants, oil, acid and alkali.  It is usually used in oil, chemical, aviation,  aerospace and other departments.

other:

Neoprene, natural rubber, EPDM rubber, acrylic  adhesive and other special rubber. With  oil, acid, alkali, wear, high, low temperature and other  characteristics.

  Rubber gasket is widely used in automotive,  electronics, chemical, anti-static, fire-retardant, food, all kinds of machinery  and equipment industries, can play a cushion, sealing, cushioning and so  on.
