teflon PFA film for PCB

teflon PFA film: 1.material:3M 2.Resistant to all solvent 3.max stand 260deg.C 4.high diaphaneity

teflon PFA  film,

Use:

AdhesiveF4 cloth belts, conveyor belts, tents, take the first adhesiveF4 plate membrane fusion weldingDielectricProduction of high-temperature adhesive tape substrateAnti-corrosion lining

Characteristics

And F4 excellent adhesion and sealing of suchBelow the melting point, wetting is not with any object. Above the melting point, and F4, metal has good adhesion. And self-adhesive (seal).High and low temperature-200 ~ 260 °CNot sticky, water fight, fight oilWater contact angle: θ = 115 °CElectricity reliability, high insulation60HZ-60MHZ both high and low temperature dielectric constant 2.1.Even the surface due to flash over and the damage it does not produce conductive tracks.Volume resistance> 1018ΩmSurface resistance> 2 X 1013ΩArc> 165 seconds without leakageHigh diaphaneityGood penetrability in ultraviolet radiation,and lowest refraction coefficientWeather resistanceCan be prolonged exposure to ozone, the sun
