Why is NBR resistant to Citric Acid?
NBR shows excellent resistance to Citric Acid due to its acrylonitrile content providing resistance to oils, fuels, and many industrial chemicals.
⚠️ When NOT to use NBR
Avoid using Nitrile Rubber (Buna-N) with strong oxidizers, ketones, chlorinated solvents, and ozone. Not suitable for polar solvents.
