What is the import of seal imports Dêngqên Dingqing rubber o-rings? Nitrile butadiene rubber is a butadiene and propylene by emulsion polymerization of green, Ding Qing rubber mainly low temperature emulsion polymerization process to produce excellent oil resistance, high abrasion resistance, good heat resistance, adhesive power . The disadvantage is poor low-temperature resistance, ozone resistance poor, poor electrical properties, elastic lower. Nitrile butadiene rubber is mainly used to produce oil and rubber products. Nitrile butadiene rubber o-ring Description: English name: nitrile butadiene rubber which is also known as NBR. Green copolymer of butadiene and propylene prepared a synthetic rubber. Is oil (especially paraffin oil), anti-aging better performance synthetic rubber. Ding Qing Qing propylene rubber content (%) 42 ~ 46,36 ~ 41,31 ~ 35,25 ~ 30, 18 ~ 24 and so on five. Green propylene content, the more oil the better, but the cold is correspondingly reduced. It can be used in an oil or long-term 150 ℃ at 120 ℃ in air. In addition, it has good water resistance, air tightness and excellent bonding properties. Widely used in making a variety of oil and rubber products, a variety of oil washers, gaskets, sleeves, flexible packaging, soft tube, printing rollers, cables and other plastic materials, in the automotive, aviation, petroleum, copying and other industries to become indispensable The elastic material.
