Fluorine rubber has better comprehensive heat and solvent resistance than other elastomers, and the vulcanizates show excellent resistance to oxidation, corrosion, weather, ozone, and flame. Fluorine rubber can be used in molding products, such as "O" rings, various seal joints, and hoses, and it is widely used in the automotive, aviation and aerospace, petroleum, and E&E industries. These excellent properties complement each other, making fluorine rubber a new type of synthetic polymer material that can not be replaced by general rubber in many application fields.
