Introduction of FEP Pellet Low Speed Process DS602

Based on its good heat resistance, corrosion resistance, oxidation resistance, non-aging, high mechanical strength, good processability and long service life, FEP resin is widely used in anticorrosive engineering industry as pipes, pipe fittings, valves, pumps, towers, etc. Lining and valves, pumps and instruments for reactors and various containers; also used in the equipment of the engineering industry to make packing, filter plates, seals, gears, bearings, bolts, nuts and corrosion-resistant fans, agitators, tanks, towers, etc. Coating of piping, piping and other products.


Composition and structure of polyperfluoroethylene propylene (FEP Resin) Perfluorinated ethylene propylene (F46) is a copolymer of tetrafluoroethylene and hexafluoropropylene. The content of hexafluoropropylene is about 18%, and it is polytetrafluoroethylene. Modified materials of Polytetrafluoroethylene; PTFE. FEP, like PTFE, is a completely fluorinated structure, except that some of the fluorine atoms in the FEP main chain are replaced by trifluoromethyl-CF3).

Main Applications

FEP Resin DS602: The low melting index resin and heat stress cracking resistant moulding plastic,used for stress cracking resistant requiring and low or medium speed processing,mainly for heat shrinkable tubes,pumps,valves,piping and lining,wire insulation layer.


Extrusion molding: generally using small diameter screw, screw diameter fan in 15mm, aspect ratio greater than 15, compression ratio of 3. The temperature of extrusion molding is usually controlled in the range of 315 ℃ to 375 ℃. Hard tubes, hoses, wire cladding and other products that can be extruded to form small straight diameters.


Instead of PTFE, FEP can be used in petroleum, chemical, electronic, electrical, mechanical industry and various advanced scientific and technical fields, such as components or coatings, etc. Electronic computers, aircraft; can also be used to manufacture various electronic components, precision instruments and instrument object parts; make anticorrosive equipment lining and surface anti-corrosion coating; make printed circuit boards, hoses, pipes, etc. It can be used to make various kinds of tube film of heat shrinkage, which is used on anti-stick and anticorrosive drum or other equipment, and its suspension can be used to impregnate glass cloth, stone cotton cloth, rope and so on as special composite material. The thin film can be used as the outer window material of solar energy collector.
