The difference between natural rubber and neoprene

May 29, 2018

The comprehensive performance of neoprene is good, and natural rubber and other synthetic rubbers are incomparable. Neoprene rubber has been widely used in various fields such as transportation, construction, light industry and military industry.

Nitrile rubber is produced by emulsion polymerization of butadiene and acrylonitrile. Nitrile rubber is mainly produced by low-temperature emulsion polymerization. It has excellent oil resistance, high wear resistance, good heat resistance, and strong adhesion. . The disadvantages are poor low temperature resistance, poor ozone resistance, poor insulation performance, and low elasticity. Nitrile rubber is mainly used for manufacturing oil-resistant rubber products. Referred to as NBR, a synthetic rubber obtained by copolymerizing butadiene and acrylonitrile. It is a synthetic rubber with good oil resistance (especially paraffin oil) and good aging resistance. The content of acrylonitrile in nitrile rubber (%) includes five types such as 42-46, 36-41, 31-35, 25-30, and 18-24. The more acrylonitrile content, the better the oil resistance, but the cold resistance is reduced accordingly. It can be used long-term in air at 120°C or in oil at 150°C. In addition, it also has good water resistance, airtightness and excellent adhesive properties. Widely used in the manufacture of various oil-resistant rubber products, a variety of oil-resistant gaskets, gaskets, casing, flexible packaging, soft hoses, printing and dyeing rollers, cable adhesive materials, etc., which are essential in the automotive, aviation, petroleum, and photocopying industries. Elastic material.
