Description:Rubber
is the most cost-effective material to use where temperatures and
pressures are low and 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.
Rubber gasket 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 gaske.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,acrylic plastic rubber gaskets and other special rubber
gaskets.
Silicon Rubber 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.
Acrylonitrile-butadiene rubber gasket(NBR):It is acrylonitrile butadiene copolymer from the emulsion
polymer.Acrylonitrile-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：Fluorine rubber gaskets can be used in a high temperature from -30℃ to +250℃.It
has the use of the environment, resistant to strong oxidant, oil.
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.

Warning: Gasket materials should
never be recommended when both the
temperature and the pressure are at
the maximums listed. Properties and
applications shown are typical. No
application should be undertaken by
anyone without independent study and
evaluation for suitability. Never
use more than one gasket in one
flange joint, and never reuse a
gasket. Improper use or gasket
selection could cause property
damage and/or serious personal
injury. The data reported is a
compilation of field testing, field
service reports and/or in-house
testing. While the utmost care has
gone into publishing the information
contained herein, we assume no
