PERFLUOROELASTOMERS
Perfluoroelastomers (FFKM) are mainly synthesized from tetrafluoroethylene, perfluoromethyl vinyl ether，and vulcanization point monomers, and have excellent resistance to chemical, heat, extrusion, and high-temperature compression deformation. Except for certain high fluorocarbon solvents,they are not affected by any medium，including ethers, ketones, esters, amides,nitriles, strong oxidizing agents, fuels, acids, alkalis, etc. It has low permeability to chemicals and gases, and good electrical properties.

Main applications
1.This product is a triazine vulcanized perfluoroelastomer,used at temperatures ranging from 275℃ to 300℃. It can be used for short periods of time at high temperatures up to 315℃. Perfluoroelastomers are used as a rubber seal and product that is resistant to high temperature.strong corrosive media, and most solvents, such as diaphragms, sealing rings, V-shaped sealing rings, O-rings, packers, solid balls, gaskets,sheaths,cups,pipes,and valves.
2.Mainly used in aviation,aerospace,chemical industry,petroleum.atomic energy, semiconductor and other felds.
Application
1.When raw perfluoroelastomers encounter fire,it will release toxic hydrogen fluoride and fluorocarbon organic compound.
2.Perfluoroelastomers cannot be mixed with metal powder such as aluminum and magnesium powder,or over 10% amine compound,if that happens, temperature will arise and several element will react with perfluoroelastomers,which will damage the equipment and operators
Package, Transportation and Storage
1.Perfluoroelastomers are packaged in PE plastic bags and then packed in cardboard boxes.Net weight is 20Kg per box.
2.Perfluoroelastomers are transported according to non-hazardous chemicals. 3.Perfluoroelastomers are stored in dean,dry and cool warehouse,and should keep away from pollution source,sunshine and water during transportation.
