What is a nitrile rubber sheet?
Nitrile rubber board people tend to write Ding rubber sheet, it is commonly known as (Ding Qing rubber board) English name nitrile butadiene rubber abbreviation: NBR nitrile rubber sheet material mainly composed of nitrile rubber
A kind of synthetic rubber by the copolymerization of butadiene and acrylonitrile is prepared. Oil resistant (especially alkane oil) and aging resistant synthetic rubber with good performance. The content of acrylonitrile butadiene rubber (%) in 42 ~ 46, 36 ~ 41, 31 ~ 35, 25 ~ 30, 18 ~ 24 and five. The acrylonitrile content more, better oil resistance, but cold resistance decreased. It can be used for a long time at the temperature of 120 DEG C in the air or at the temperature of 150 DEG C oil. In addition, it has good water resistance, air tightness and excellent bonding properties.
Nitrile rubber plate and polar nitrile rubber is very strong, the compatibility with other polymers is generally not too good, but and chloroprene rubber, phenolic resin, polyvinyl chloride and other polar polymers, especially with chlorine containing polymers and good compatibility, and often used. In addition, in order to improve the processing performance of nitrile rubber, often with natural rubber, styrene butadiene rubber, polybutadiene rubber and other non-polar rubber and use. It should be pointed out that the characteristics of nitrile rubber plate is good oil resistance, and other polymers and use (except PVC outside) exist in the lower oil resistance trend.
Widely used in various kinds of oil resistant rubber, oil resistant gasket, gasket, sleeve, flexible packaging, soft hose, rubber roller, rubber cable printing and dyeing materials, become the indispensable elastic material in automobile, aviation, petroleum, copy and other industries. The basic properties of nitrile rubber plate: nitrile rubber plate has excellent oil resistance. The oil resistance after polysulfide rubber and fluorine rubber, and the wear resistance and air tightness of the NBR. The weaknesses of the board is not resistant to ozone and aromatic, halogenated hydrocarbon, ketone and ester solvents, insulation materials do not.
