Rubber Gasket Material Selection Guide

1. The main products of Rubber Sealing Gasket are: silicone pad, nitrile rubber cushion, fluorine-rubber pad, other rubber gasket.

Rubber Gaskets are made of a variety of different materials.Today, we would like to introduce you some main rubber gasket material.

Rubber Molding Compounds Materials

  • Neoprene®, Chloroprene (CR)                                                                                           

  •  Nitrile, Buna-N (NBR)

  • Hydrogenated Acrylonitrile (HNBR)

  • Epichlorohydrin (EPI)

  • Ethylene-Propylene (EPDM, EP, EPT)

  • Viton®, Fluorocarbon (FKM)

  • Silicone (VMQ)

  • Fluorosilicone (FVMQ, FMQ)

rubber gasket

-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 make adiabatic, insulation products and medical rubber products.With waterproof, flame retardant, 

high temperature, conductive resistance, abrasion resistance, oil resistance and other excellent performance, 

widely used in mechanical, electrical, plumbing and other industries, the company produces silica gel pad is in line 

with eu environmental standards and the eu food grade standard.

Rubber gasket for short WMQ, silicone rubber has the outstanding resistance to high and low temperature performance, in - 70 ℃ to + 260 ℃ temperature range to maintain good flexibility, and has the advantages of resistance to ozone, weather aging, appropriate for the thermal mechanical seal gasket.There is no toxicity to make adiabatic, insulating products and medical rubber products.At the same time, it is waterproof, flame retardant, high temperature resistant, conductive, wear-resistant, oil resistant and other excellent properties, widely used in machinery, electronics, water and other industries.

-Nitrile rubber

NBR (Nitrile - Butadiene Rubber) is composed of Butadiene and acrylonitrile by emulsion copolymerization of polymers, renowned for its excellent oil resistance, but also has good abrasion resistance, aging resistance and air tightness, which are widely used in Rubber industry.

-Fluorine rubber

With high temperature resistance, can be in - 20 ℃ to + 200 ℃ environment, strong oxidant, oil resistant, resistant to acid and alkali resistance.Generally used for high temperature, high vacuum and high pressure environment, it is also suitable for oil environment, widely used in oil, chemical, aviation, aerospace and other departments.


-Chloroprene rubber, natural rubber, triglyceride, acrylate and other special rubber.It has the characteristics of oil resistance, acid, alkali, abrasion resistance, high and low temperature.

Main parameters of rubber gasket material

The product name USES the temperature to use the pressure commonly used specifications

-Nitrile rubber gasket - 20 ℃ ~ 110 ℃ PN < = 16 mpa DN15 ~ DN400

-Fluorine rubber gasket - 20 ℃ ~ 200 ℃ PN < = 16 mpa DN15 ~ DN400

-Natural rubber gasket - 50 ℃ ~ 80 ℃ PN < = 16 mpa DN15 ~ DN400

-Neoprene gasket - 20 ℃ ~ 100 ℃ PN < = 16 mpa DN15 ~ DN400

-EPDM  gaskets - 57 ℃ ~ < 176 pressure 2.5 MPa DN15 ~ DN400

-Rubber gasket - < 100 ℃ ~ 300 ℃ pressure 3.0 MPa DN15 ~ DN400

3. Application field:

Rubber Gasket material has the properties of oil resistance, acid and alkali resistance, cold resistance and aging. It is widely used in automobile, electronics, chemical industry, anti-static, flame retardant, food and other industries.
