What is the chemical compatibility of rubber?

The chemical compatibility of rubber is extremely important as the rubber can degrade rapidly if the rubber material is not compatible with the environment or media that it comes into contact with. Shell 3XF Mine Fluid (Fire resist hydr.) This is page 5 of our chemical compatibility and resistance chart of all popular rubber or elastomer materials.

How do I know if a rubber elastomer or O-ring seal is compatible?

Use this rubber chemical resistance chart to make sure that the elastomer or O-ring seal you choose will be compatible with the particular environment. The chemical compatibility of rubber is extremely important as the rubber can degrade rapidly if the rubber material is not compatible with the environment or media that it comes into contact with.

How do you know if a rubber is good?

The Durometer / Hardness of the Rubber. Generally speaking, the harder the rubber material, the greater its chemical resistance. Conditions of Service. A rubber that swells when used in conjunction with a particular fluid may be perfectly fine for sealing in a static application yet fail in a dynamic sealing environment.

What factors should be considered when selecting a rubber sealing material?

In addition to chemical resistance, many other factors must be considered when selecting a rubber sealing material. These include: The Grade of the Elastomer. There are many, many different rubber manufactuers. All use slightly different formulas and variable amounts of filler compounds.

Why do rubber seals fail at room temperature?

The degree of the increase will vary depending on the particular type of rubber and the chemical. As a result, a rubber that might seal a particular chemical perfectly well at room temperature could fail if subjected to higher temperature conditions. The Durometer / Hardness of the Rubber.
