PTFE sewing thread 600D_ environmental Hao Yun (certified) _PTFE sewing thread by Jiang 苏皓润 Environmental Technology Limited. Jiang Su Haorun Environmental Protection Technology Co., Ltd. (www.jshrhb.com) is specialized in the "steel cable bridge, fire-retardant aluminum tray, glass fiber reinforced epoxy composite bridge, Busway" enterprise, the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Wuji Bing. Teflon is not a replacement for summarized under what circumstances can be replaced, asbestos, graphite, rubber, nylon, PTFE seals, etc. may be used instead. If you need to corrosion, high temperature, such as overall performance and PTFE materials have, poly FEP, PTFE, but the temperature is not so high temperatures. Poly FEP referred FEP (F46) of the material and polytetrafluoroethylene (F4) almost wholesale PTFE sewing thread, mostly fluorine plastic, high temperature resistance, self-lubricating, resistant to chemical corrosion. Poly FEP can also injection molding, recycling is easy, comprehensive performance of Wu had less, but the price is much higher than polytetrafluoroethylene (F4). If you suspect Teflon PTFE sewing thread performance is not enough, consider PTFE PTFE sewing thread 600D, where you can fill in some Teflon carbon fiber, copper powder, polyphenylene ester reinforced materials, raising his performance and life. Teflon FEP: FEP or F46 (fluorinated ethylene propylene copolymer) nonstick coatings melt flow during baking to form a non-porous film with excellent chemical stability, excellent non-stick properties of PTFE sewing thread filament The maximum use temperature of 200 ℃, melting point of 270 ℃, can injection molding, extrusion molding. Teflon PFA: PFA (perfluoroalkyl compounds) non-stick coating and FEP melt flow during baking to form a non-porous film. PFA has the advantage of a higher continuous use temperature of 260 ℃, more just toughness, particularly suitable for use in the release and chemical resistance under high temperature conditions used in the field. Can fit any process.
