tetrafluoroethlene - Ethylene Copolymer ETFE (F-40)-lined pipe

 

 

 

 

 

ETFE (F-40) is a kind of semicrystalline and semitransparent polymer, which is made by ethylene and tetrafluoroethlene through copolymerization with equal mol ratio. It keeps the good anticorrosion property of polytetrafluoroethylene, and has good heat resistance, wear resistance, radiation resistance and impact resistance and electrical insulation properties. It can apply the forming method of general thermoplastics to carry out machining, without surface self-lubricating ability, and the coefficient of friction is large, the tensile strength can be up to 500MPa. With long-term application temperature of -60~150°C, and thermal decomposition temperature of above 300°C, it almost proofs against all chemical substances.
