SELF-FUSING SILICONE TAPE
Chemical Resistance Report
Includes Black, Clear, and Colors
Silicone rubber has good resistance to many chemicals, fluids and oils
encountered in extreme environments.
Dilute Acids, Alkalis and Aquous Salt Solutions:
Whether hot or cold, these solutions have a negligible effect on silicones.
Concentrated Acids and Alkalis:
Silicones are attacked by concentrated acids and alkalis, especially oxidizing acids such as
sulphuric acid.
Polar Liquids:
Short chain alcohols and acetone cause very little swelling and can be used in appropriate
applications.
Nonpolar Liquids:
Linear or cyclic hydrocarbons, aliphatic or aromatic mineral oils, gasoline etc. cause severe
swelling. They can only be used to a very limited extent.
The following table lists the effect of various chemicals on silicone rubber when
fully immersed for 336 hours at room temperature and 120 °F.
