EPDM Rubber Flat Washers Galvanized Black Color Steel For Self Drilling Screw

Rubber gasket oil, acid and alkali to cold, heat resistance, aging resistance, can be directly cut into various shapes of sealing gaskets, widely used in medicine, electronics, chemical industry, antistatic, flame retardant, food and other industries.

Rubber gasket rubber gasket in metal flange or other parts of the two static sealing effect between the surface of the chip shape rubber products generally referred to as the rubber gasket.Available compression molding manufacturing, also can use sulfide film system.Can be widely used in various mechanical equipment, gasket, seal, such as buffer role.[1]
Tell from form, commonly used rubber gaskets gasket including: flat washer, rubber o-ring, rubber plastic flat gasket, ptfe gasket, asbestos rubber gasket, metal flat washer, metal profile gasket, metal wrapping washers, wave washers, winding gasket, etc.
(1) rubber flat washer, easy deformation, compression without effort, but the pressure and temperature resistant ability is poor, only for low pressure and temperature is not high.Natural rubber is, to some extent, acid-proof alkaline can use temperature should not be more than 60 ℃;Neoprene also ability some acid and alkali, temperature 80 ℃;Nitrile rubber oil resistant, available to 80 ℃;Fluorine rubber corrosion resistant performance is good, heat resistance performance is better than general rubber, can be used in the 150 ℃ medium.
(2) the rubber sealing gasket: cross section shape is round, there was a self-tightening effect, the sealing effect is better than flat washer, smaller compression force.

Silicone rubber
The high and low temperature resistance, with a prominent - 70 ℃ to + 260 ℃ temperature range to maintain the use of good elasticity, resistance to ozone, weather aging, appropriate for the thermal mechanical seal gasket.Non-toxic can produce thermal insulation, insulation products, and medical rubber products.At the same time has the waterproof, flame retardant, resistance to high temperature, conductive, abrasion resistance, oil resistance and other excellent properties, widely used in mechanical, electrical, plumbing and other industries.
