What are the materials of commonly used sealing gaskets and rubber gaskets?
Apr 24, 2018
The main products of rubber gaskets are: O-ring gaskets, silicone gaskets, butadiene [nitrile] rubber gaskets, neoprene gaskets, EPDM rubber gaskets, fluororubber gaskets and other rubber gaskets.
Commonly used materials are neoprene rubber, natural rubber, EPDM rubber, acrylate rubber and other special rubber gaskets, and the physical properties are resistant to oil, acid, alkali, abrasion, high temperature and low temperature.
In terms of use, there are EPDM rubber (mainly required for gaskets with water resistance, water vapor resistance, and aging resistance), natural rubber (mainly used for gaskets that generally only require elasticity), and butyl rubber (gaskets requiring good sealing performance) , nitrile (requires oil-resistant gaskets), silica gel (food-grade gaskets); gaskets and rubber gaskets are widely used in antistatic, flame retardant, electronics, chemical, pharmaceutical, food and other industries.
There are also special fluorine rubber and silicone rubber gaskets with wear resistance, pressure resistance and high temperature resistance. Rubber gaskets made of NBR, SBR, CR, EPDM...etc materials have two states: elastic (foamed air cell structure) and solid type, which can meet different sealing, heat insulation, sound insulation, cushioning, waterproof and gas Confidentiality [function] and so on. With oil resistance, acid and alkali resistance, cold and heat resistance, aging resistance, etc., rubber gasket manufacturers can make rubber gaskets into various shapes of sealing gaskets in terms of customization.
