HRN-13 PTFE Rolling Equipment HRN-13
ETFE (F-40) is formed by copolymerizing tetrafluoroethylene and ethylene in the ratio of 1:1 and is made by DuPont Co., Ltd. and Asahi Glass Co., Ltd. ETFE (F-40) is mainly applied to anti-corrosion liners. The material has the corrosion resistance of polytetrafluoroethylene and a peculiar high property of adhesion to metal and overcomes the defect that tetrafluoroethylene does not adhere to metal, and the average linear expansion coefficient of ETFE (F-40) is approximate to the linear expansion coefficient of carbon steel. Therefore, the material become an ideal material compounded with metal, and has extremely high negative pressure resistance.
Fluorine plastic and metal composite technology is DuPont’s R&d results,this is a new technology. Using reasonable formula and the best thickness to sinter the plastic and carbon steel together. It’s characteristic is the plastic can combined with carbon steel effectively,can be synchronized expansion coefficient,don’t need to welding,without air bubbles,well permeability resistance,small coefficient of friction etc.
