Special material for automotive air conditioning O-rings
First, the classification of rubber
1, according to sources of raw materials and Method: rubber can be divided into natural rubber and synthetic rubber two categories. Wherein the consumption of natural rubber 1/3, 2/3 synthetic rubber consumption.
2, according to the morphology of rubber: rubber can be divided into solid rubber (also known as adhesive), emulsion rubber (referred to latex), liquid rubber and powder rubber four categories.
3, the rubber properties and applications: In addition to natural rubber, the synthetic rubbers can be divided into general synthetic rubber, synthetic rubber, semi-universal, dedicated special synthetic rubber and synthetic rubber.
4, according to the physical form of rubber: rubber can be divided into soft and hard plastic, raw rubber and rubber compounds and the like.
Hydrogenated nitrile rubber O-ring wear corrosion resistance to compression variant
Hydrogenated nitrile rubber (HNBR) air-conditioning for O-rings
Has excellent corrosion resistance, tear and compression set properties, resistance to ozone, sunlight, weather resistance is better. There is a better abrasion resistance than nitrile rubber. Suitable for washing machines, car engine system and the use of new environmentally friendly refrigerant R134a refrigeration systems. Not recommended for use in alcohols, esters, or aromatic solution. General temperature range of -40 ~ 150 ?.
