Factory overview of NBR NBR joint use of the advantage.
Nitrile rubber joint is also called diene ethylene-propylene rare nitrile rubber, NBR for short, average molecular weight of 700000 or so, nitrile rubber with good oil resistance, the oil resistance after thiokol and fluorine rubber, and the abrasion resistance and air tightness, thermal stability is better than that of styrene-butadiene rubber, neoprene, medium and long term working in 120 degrees, air tightness after butyl rubber, nitrile rubber performance is affected by the acrylonitrile content, the propylene content increase tensile length, heat resistance, oil resistance, air tightness, hardness increased, but elastic, cold resistance is reduced, NBR ozone resistance and electrical insulation, good resistance to water.
