Chemical Resistance Guide
Elastomer Chemical Compatibility Guide
Resistance ratings for common seal elastomers — including NBR, FKM, EPDM, silicone and more — across hundreds of chemicals, fuels and process media. Engineers use it to match a compound to the fluids, temperatures and exposure a part will see, then ARC molds that compound to your exact spec.

This elastomer chemical resistance chart pairs common seal compounds — NBR (Buna), FKM (Viton-type), EPDM, silicone, HNBR, neoprene and more — against hundreds of chemicals, fuels, oils and process media. When engineers search for an o-ring chemical compatibility chart or a rubber material resistance guide, they use it the same way: find each fluid your part contacts, read the resistance rating for every candidate elastomer, then narrow to the compounds that hold up against your full media list, service temperature and exposure time. It is the fastest way to rule out a material that will swell, harden or degrade before you commit to tooling.
Once you have a shortlist, ARC molds it to spec. We supply custom seals, o-rings and molded rubber parts in the compound and durometer your application needs, backed by ISO 9001:2015 and IATF 16949:2016 quality systems and 20 years of US manufacturing. Send your media, temperature range and drawing or dash number and our engineers confirm the compound, hardness and a fast quote to production.
Chemical Compatibility Guide for Material Selection
Our engineers spec the right elastomer for your chemical environment — including temperatures, concentrations, and cycle requirements not captured in this reference table. ISO 9001:2015 + IATF 16949 certified.
