Is NBR compatible with Sodium Hydroxide (Caustic Soda)? See the chemical resistance rating below.

Compatibility Rating

At 20°C (68°F)
C
Fair
Limited resistance - short-term exposure only
At 50°C (122°F)
D
Poor
Not recommended - significant degradation expected

Why is NBR rated this way to Sodium Hydroxide Caustic Soda?

NBR has limited resistance to Sodium Hydroxide Caustic Soda. Short-term exposure may be acceptable, but prolonged contact is not recommended.

⚠️ When NOT to use NBR

Avoid using Nitrile Rubber (Buna-N) with strong oxidizers, ketones, chlorinated solvents, and ozone. Not suitable for polar solvents.
