Chemical Resistance Chart - Elastomers

Elastomer	Acid Resistance	Alkali Resistance	Oil Resistance	Solvent Resistance
Natural Rubber	Poor	Fair	Poor	Poor
Butyl Rubber (Buna-N)	Excellent	Good	Excellent	Good
EPDM (Ethylene Propylene Diene Monomer)	Fair	Fair	Poor	Good
Nitrile Rubber (NBR)	Good	Fair	Excellent	Excellent
Fluorocarbon (FKM)	Excellent	Fair	Excellent	Excellent
Silicone (VMQ)	Poor	Poor	Poor	Good

It’s important to note that the resistance of an elastomer to a specific chemical can depend on factors such as concentration, temperature, and exposure time. Therefore, it’s always best to consult with a materials expert to select the best elastomer for your specific chemical exposure requirements.
