The Introduction of FEP Powder Thermoplastic processing DS605

There are many kinds of fluorine resin, according to the number of fluorine atoms in the molecule, there are the following varieties: polyfluoroethylene (PVFN), referred to as F1; polyvinylidene fluoride (PVDF), referred to as F2; polytrifluoroethylene chloride (PCTFEN), referred to as F3; polytetrafluoroethylene (PTFE), abbreviated as F4; polyhexafluoropropylene, abbreviated as F6. The copolymers of fluorinated plastics have the following varieties: soluble polytetrafluoroethylene (PFA) is composed of polytetrafluoroethylene (PTFE) and perfluoroalkylvinyl ether (PFE); It is the copolymer of tetrafluoroethylene and hexafluoroethylene, the copolymer of tetrafluoroethylene and vinylidene fluoride, the copolymer of tetrafluoroethylene and ethylene for short, the copolymer of tetrafluoroethylene and ethylene, and the copolymerization of trifluoroethylene and ethylene. F 23 (3 M) is a copolymer of vinylidene fluoride and trifluoroethylene.

FEP (Fluorinated Ethylene Propylene) is another melt-processable Fluoropolymer. It does not have the almost universal chemical resistance of PTFE and PFA and its maximum operating temperature in service is 150oC. CRP uses the material occasionally for the manufacture of "sheet lined products". This is essentially a lining made up of sheet and tube elements of FEP welded together in situ. Sheet lining allows one to line complex articles without the use of expensive moulding tools, to cope with the inevitable tolerance errors of welded fabricated steelwork and with the use of bonded linings to provide a degree of vacuum performance. Where the chemical performance and temperature duty are not an issue, the material provides a less expensive alternative to PFA. Flowserve manufacture the Atomac range of valves lined in FEP.

Main Applications

Lining valve is the product of the development stage of modern science and technology. Fluoroplastic lining valve is a high-tech product with the appearance of fluoroplastics and social demand. A series of fluoroplastic lining valves have been developed according to the above properties and forming process characteristics and methods of fluorine plastics. Fluoroplastic lining valves have their own characteristics, both in material selection and manufacturing process, compared with conventional universal valves. Fluoroplastic lining valve structure length and flange end dimensions, according to steel valve standards and industry standards. If the structural length according to the GB/T 12221 standard, the structural length includes flange sealing face lining fluorine plastic thickness.
