Fluoroelastomer Chemical Resistance Guide
The following chemical resistance evaluation of fluoroelastomers
This polymer is rated for use in individual chemicals at room temperature. Where multiple chemicals are in use, refer to the rating of the most aggressive fluid when evaluating performance.
The criteria used for the ratings were primarily volume swell resistance, compression set resistance, and in addition, aging resistance. For the most part the ratings were arrived from specific data or general agreement of the above sources. When no data or agreement was found, the ratings were arrived at by theory and analogy. In some cases they are the considered opinion of experienced compounders. We cannot guarantee their accuracy nor assume responsibility for their use. Several factors must always be considered when using a rubber part in service. The most important as we see them are:
Higher temperatures increase the effect of all chemicals on polymers. The increase varies with the polymer and the chemical. A compound quite suitable at room temperature might fail miserably at elevated temperatures.
A compound that swells badly might still function well as a static seal yet fail in a dynamic application.
Fluoroelastomers are available in different grades that vary in chemical resistance. Mission's compound uses a dipolymer, having 66% fluorine, similar to Viton A
Compounds designed for other outstanding properties may be poorer in performance in a chemical than one designed especially for fluid resistance. In light of these factors, it is always best to test.
All Mission Rubber Company's products are manufactured at an ISO 9001 registered facility.
