Emulsion polymerization of perfluoro(methyl vinyl) ether, tetrafluoroethylene and a small amount of perfluoroalkene ether with peroctanoic acid saddle as dispersant and ferric persulfate-sodium sul...

It has the thermal and chemical stability of elasticity and polytetrafluoroethylene.

Oxygen in the rubber undergoes a free radical chain reaction with the rubber molecules, and the molecular chains are broken or excessively cross-linked, causing changes in the properties of the rub...

During the processing, storage and use of rubber and its products, due to the comprehensive action of internal and external factors, the physical and chemical properties and mechanical properties o...

Fluorosilicone oil can be chemically adsorbed on the surface of the substrate to form a molecular assembly film with the outer chemical composition of -CF3 and high hydrophobicity and oleophobicity...

O-ring seals are suitable for installation on various mechanical equipment, and play a sealing role in static or moving states under specified temperature, pressure, and different liquid and gas me...

There are three main preparation methods of HNBR: ethylene-acrylonitrile copolymerization method, NBR solution hydrogenation method and NBR emulsion hydrogenation method.

The high temperature resistance of HNBR is 130～180℃, the cold resistance is -55～-38℃ and the mechanical properties are excellent.

Hydrogenated nitrile rubber is widely used in oil fields, automobile industry and so on.

Hydrogenated nitrile rubber is a product obtained by hydrogenation of carbon-carbon double bonds in the molecular chain of nitrile rubber, so it is also called highly saturated nitrile rubber.

In the 1930s, developed countries successively developed organosilicon and organofluorine materials.

Fluorosilicone compounds are mainly used in the fields of aerospace, vehicles and ships, electronic communications, precision instruments, petrochemicals, and medical care, but the rocket, satellit...
