Rubber Products : It is widely used in industry , agriculture , national defense , transportation , transportation , machinery manufacturing , medicine and health fields and daily life , such as tires used in transportation ; transportation belts , transmission belts , various sealing rings for industrial use ; medical gloves and blood vessels ; rubber shoes , raincoats , warm water bags used in daily life are all made of rubber as the main raw material . Aircraft , cannons , tanks used in national defense, and even rockets , artificial satellites , spacecraft , spacecraft , space shuttles , etc. used in the field of cutting - edge science and technology , require a large number of rubber parts .
O Ring Seal Materials
FKM:FKM has excellent heat resistance, oxidation resistance, oil resistance, corrosion resistance and atmospheric aging resistance. It has been widely used in aerospace, aviation, automotive, petroleum and household appliances, and is an irreplaceable key material in cutting-edge defense industries
FKM advantage:
1 . Excellent stability :FKM has a high degree of chemical stability and is the best medium resistance of all elastomers
2 . high - temperature resistance :The high temperature resistance of fluorine rubber and silicone rubber , can be said to be the best elastomer .
3 . ageing resistance :Fluorine rubber has excellent weathering resistance and ozone resistance.
4 . Excellent vacuum performance.
5 . Excellent physical and mechanical properties
6 . The solubility of the gas is relatively large, but the diffusion speed is relatively small, so the overall performance of the air permeability is also small.
FKM has the characteristics of high temperature resistance, oil resistance, high vacuum resistance, acid and alkali resistance, and a variety of chemical drugs. It has been applied to modern aviation, missile, rocket, space navigation, naval ships, atomic energy and other cutting-edge technologies and automotive, shipbuilding, chemical, petroleum, telecommunications, instruments, machinery and other industrial fields.
NBR:NBR is a copolymer of acrylonitrile and butadiene monomer polymerization, mainly produced by low temperature emulsion polymerization, excellent oil resistance, high wear resistance, good heat resistance, strong adhesion. Its disadvantages are poor low temperature resistance, poor ozone resistance, poor insulation performance, low elasticity.
NBR is mainly used to manufacture oil resistant rubber products. Acrylonitrile content in nitrile butadiene rubber (%) has 42 ~ 46, 36 ~ 41, 31 ~ 35, 25 ~ 30, 18 ~ 24 and other five kinds. The more acrylonitrile content, the better oil resistance, but cold resistance is decreased. It can be used in 120℃ air or 150℃ oil for a long time. In addition, it also has good water resistance, air tightness and excellent bonding properties. It is widely used to produce all kinds of oil-resistant rubber products, a variety of oil-resistant gaskets, gaskets, bushing, flexible packaging, flexible hose, printing and dyeing roller, cable adhesive materials, etc. It has become an indispensable elastic material in automobile, aviation, petroleum, photocopying and other industries.
