Rubber Compounds Used for the Manufacture of Rubber Gaskets


Rubber gaskets are commonly used as seals to prevent leaks between two separate substrate sections.  Rubber gaskets are cut or punched to shape from rubber sheets. Here are some of the rubber compounds that are normally used to manufacture rubber gaskets:

Acrylonitrile-butadiene rubber

This rubber compound can be used in both high and low temperature applications. Acrylonitrile-butadiene rubber has good resistance to hydrocarbons and oil. However, it is not suitable for ketones, esters, chlorinated hydrocarbons and other strong oxidising agents.


Silicone has excellent temperature resistant properties and does not get affected by sunlight and the ozone. However, it is not suitable for many hydrocarbons and steam. Its temperature resistance is 60°C to 200°C.

Chlorbutadiene rubber

Chlorbutadiene rubber is not recommended for strong acids or hydrocarbons. However, it has excellent resistance to oil, the ozone and weathering. It can withstand temperatures of-45° C up to 100°C. It is suitable for moderate acid, alkali, salt solutions, petroleum, solvents and fuel.

Natural rubber

With a temperature resistance of between -60°C to 80°C, natural rubbers have good recovery properties. These rubbers are also resistant to most inorganic salts, mild acids and alkalis. Natural rubber is recommended for applications that involve solvents and oil or exposure to oxygen, the ozone or prominent sunlight.

Ethylene propylene diene rubber

This rubber material is highly resistant to steam, the ozone, alkalis and strong acids. On the other hand, Ethylene propylene diene rubber is not suitable for aromatic hydrocarbons and solvents. This rubber can withstand temperatures from between -50°C to 150°C.

Butyl rubber

Butyl rubber is suitable for mild esters, acids and alkalis. Able to resist temperatures of between 40°C to 150°C, Butyl rubber has little resistance to fuel and oil, although it has good resistance to gas permeation and the ozone.

Styrene butadiene rubber

Styrene butadiene is able to withstand temperatures of between -50°C to 100°C. This rubber compound has little resistance to the ozone or hydrocarbons and strong acids but it is highly suitable for use with moderate chemicals and weak organic acids.


The fluorocarbon-based synthetic rubber is excellent for greases and oil, aromatic hydrocarbons, as well as aliphatics. Its temperature resistance is from 20°C up to 200°C.
