NBR
- Acrylonitrile Butadiene Rubber
-
KUMHO KNB is a synthetic rubber product manufactured by emulsion-polymerizing acrylonitrile and butadiene in low temperature and has great oil and chemical resistance. Our NBR product is easy to process because of its good usability such as roll winding property, mixing dispersibility, and extrudability and of proper vulcanization characteristic. It can be used for packings requiring oil resistance, gaskets, hoses, rolls, shoes, and electronic parts.
Usage
- Fuel hoses
- Oil hoses
- Seals
- Gaskets
- Print rollers
- Foam insulation for construction
Features
- Excellent oil resistance and electrical conductivity
- Great of processability and mechanical property
