NBR
NBR (Nitrile Rubber)
Cost-effective oil-resistant rubber for general industrial seals, gaskets, and fluid-control components.
Answer-First Summary
- Temperature Range: -30 C to +120 C, compound-dependent
- Media Profile: Petroleum oils, greases, and general industrial fluids
- Engineering Role: Workhorse sealing material for repeatable industrial programs
Good Fit
Best fit when oil resistance, stable molding, and sensible cost matter more than extreme heat or weather exposure.
Typical Application Windows
Hydraulic seals
Oil-contact gaskets
General machinery molded parts
