         fluorine ethylene propylene copolymer (full fluorine ethylene propylene copolymer), 英文名Fluorinated Ethylene Propylene, 简称FEP, 俗称F46. FEP is fluorine ethylene (TPFE) and fluorine propylene copolymer formed. FEP crystallization 熔化点 is 304℃, density is 2.15g/CC(克/立方 cm).

        FEP can application to soft property plastics, its tensile strength, wear resistance, resistant creep property low many engineering plastics. it tool relatively good chemical inert property, relatively wide temperature degree and frequency rate scope/range, and relatively low dielectric constant. therefore FEP film by by widely used in chemical and product 密封层, electrical container 介质, specialty cable insulation 层, insulation, electrical appliances table/sheet insulation and 密封衬垫. in 5G通讯时代, FEP film by research used for FCCL insulation 层.

        如 lower is certain Brand FEP resin film property can

         insulation property can

        FEP材 material electrical insulation property can and PTFE (TPFE)十 separation versus 近. it electrical from deep cold to most high as temperature degree, from 100Hz to 1MHz ultra-high frequency vast scope/range inner 几乎不变, and very low, upper in FEP film dielectric constant 变化. loss consumption positive frequency rate 变化则 has 变化, temperature degree 变化不 large, upper parameters in consumption dispersion factors related parameters.

        FEP resin volume resistivity very high, to 1018Ω·m, temperature degree 变化甚 micro, 也不受 water and gas effect/influence. resistant electrical large 于165s, FEP 击穿场随 thick degree decrease/reduce improve/increase, thick degree large 于1mm时, 击穿场 strong/high in 30kV/mm above, 但不随 temperature degree 变化而变化.

         chemical resistant stability property

        FEP resin chemical resistant stability property and poly fluorine ethylene versus 似, tool has excellent chemical resistant stability property. remove and high temperature lower fluorine 元素, melt alkali metal and fluorine chlorine and other reaction outer, and other chemical product 接触时均不 by 腐蚀.

         force property can

        FEP resin and PTFE versus ratio, hardness and resistant strong/high degree has improve/increase, friction coefficient ratio PTFE large. normal temperature lower, FEP tool has relatively good creep resistance can;但当 temperature degree high 于100℃时, creep resistance can 反而不 and PTFE.

         in addition, is FEP良 good property can, currently in electronics industry, 也广泛 and PI film, LCP film and other composite/compounding, improve/increase product comprehensive property can.
