CHEMICAL RESISTANCE GUIDE FOR THORDON ELASTOMERS XL, SXL, COMPAC, Composite (GM2401), RiverTough, HPSXL, Thorseal

Updated: January 19, 2021

Thordon elastomers possess excellent corrosion resistance and are resistant to oil, water and most chemicals. They are not affected by lubricants normally used with sleeve bearings. Thordon elastomers are unaffected by mild acid or caustic baths (pH 5-10) or other chemical environments which would be harmful to metallic bearings. The following list shows a selected group of chemicals and their effect on Thordon elastomers. However, it should be used as a guide only. Results can change depending on concentration, temperature, aeration, velocity of flow, duration of exposure, stability of the fluid, degree of contact, and pressure, etc. For critical applications it is recommended that an immersion test be performed to determine whether or not Thordon elastomers will be safe to use. Significant softening or dimensional changes after twenty- four hours of immersion at application temperatures will indicate that a Thordon elastomer is unsuitable for that application.
