Product Description
NBR Sealing O-Rings with Superior Wear Resistance
Nitrile butadiene rubber (NBR) black O-rings offering excellent wear resistance and elongation properties. These seals provide reliable performance in various industrial applications with a hardness range of 70-90 Shore.
Material Composition & Properties
NBR is copolymerized from acrylonitrile (18-50%) and butadiene. Higher acrylonitrile content enhances resistance to petrochemical hydrocarbon fuels while maintaining operational capability from -25°C to 100°C.
