Kinds of Rubber Gaske
Description: Rubber is the most cost-effective material to use where temperatures and pressures are lowand
the chemical environment is mild. Different elastomers offer different mechanical and chemical properties. Cloth
inserted materials are better able to handle movement and high compression loads.
Rubbergasket is cut or molded from NBR, SBR, CR, EPDM. Some rubber gasket have resisttance of oil, Some
rubber gasket is used in cold fever, Some rubber gasket has anti-aging properties.There are various shapes of
rubber gasket. Rubber gaskets are widely used in medicine, electronics, Chemical, anti-static, fire-retardant, food
and other industries.Other rubber gaskets: neoprene rubber gaskets, natural rubber gaskets, EPDM rubber
gaskets, acrylicplastic rubber gaskets and other special rubber gaskets.
SiliconRubber Gasket: Silicon rubber gasket(WMQ) has outstanding low-temperature-resistant high-performance.
BIK-silicon rubber gasket can be used in -70℃ - +260℃ temperature range. Silicon rubber gasket (WMQ) maintain
good use of bombs.
Nitril-butadiene rubber gasket(NBR): It is Nitril butadiene copolymer from the emulsion polymer. Nitril-butadiene
rubber gasket BIK-30207B has excellent oil resistance(but intolerance ketones, esters and chlorinated hydrocarbons,
and other media). It also has a good abrasion resistance, anti-aging and air tightness and therefore the application
of the rubber industry Wide.
Fluorine Rubber Gaskets：Fluorinerubber gaskets can be used in a high temperature from -30℃ to +250℃. It has
the use of the environment, resistant to strong oxidant, oil. And normally, Fluorine rubber gaskets are used for high
temperature, high vacuum and high-pressure environment. Fluorine rubber gaskets is also suitable for oil environment.
As with all high-performance, fluorine rubber is widely used in petroleum, chemical, aviation and aerospace sectors.
Other rubber gasket: Neoprene Rubber Gasket(CR), Natural Rubber Gasket(NR), EPDM Gasket, ect.
