Why is NBR resistant to Formaldehyde?

NBR shows good resistance to Formaldehyde 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.
