Rubber is a very common industrial raw material, rubber products are widely used in medical, machinery, chemical, hardware, automotive and other fields.
Rubber products have a lot of material classification, different materials will also correspond to different use scenarios
·Nitrile rubber
Nitrile rubber is mainly used in the manufacture of oil-resistant rubber products. Acrylonitrile content (%) in nitrile rubber is 42 ~ 46, 36 ~ 41, 31 ~ 35, 25 ~ 30, 18 ~ 24 and other five kinds. The more acrylonitrile content, the better the oil resistance, but the cold resistance is decreased accordingly. It can be used in air at 120 ° C or oil at 150 ° C for a long time. In addition, it also has good water resistance, air tightness and excellent bonding properties. Widely used in the production of a variety of oil-resistant rubber products, a variety of oil-resistant gaskets, gaskets, bushings, flexible packaging, soft hose, printing and dyeing roller, cable rubber materials, etc., in the automotive, aviation, petroleum, copying and other industries to become an essential elastic material.
·Fluorine rubber
Fluorine rubber has a high degree of chemical stability and is the best medium resistance of all elastomers at present.In addition to good oil resistance and high temperature resistance, as well as good corrosion resistance, in addition to common areas, fluorine rubber products also have good application prospects in the field of chemistry
·Silicone
Silicone has better safety, is the most widely used in the food field, and has the function of waterproof, cups, pressure cookers and other items need food-grade silicone materials, in addition, in the medical field, silicone also plays a huge role
