Chemical Resistance Chart
This guide is intended to provide assistance in determining the suitability of commercially available Elastomers, Engineering Plastics and Ferrous and Non-Ferrous Metal for service in over 1,600 chemicals and fluids for ultimate temperature and chemical resistance. The criteria used for these ratings included volume swell resistance based on laboratory immersion testing, actual field experience and based on experience in similar chemical groups.
The ratings are based on published literature and are offered for general comparative purposes only. We cannot guarantee their accuracy and it is the ultimate responsibility of the end user to determine the compatibility of the chemical being used in his or her particular application.
We have made it much easier by transferring all this information onto our website.
Rating System
- A - Elastomer shows little or no effect (generally less than 10% swell) after exposure to the chemical
- B - Moderate swelling and change in physical properties, good 10–20%. May be suitable for static applications
- C - Significant swelling and noticeable change, doubtful 20–40%, in physical properties.
- D - Elastomer is not suitable, 40%, for service in the chemical.
- N - No Data
