PFA Teflon plate welding welding film

Soluble Teflon PFA film, PFA welding film, PFA welding rod use adhesive F4 cloth belts, conveyor belts, head tent melt adhesive bonding film F4 board dielectric substrate adhesive tape making high soluble anti-corrosion lining PTFE PFA utilization characteristics vinyl film resistant to high temperature: -200--200 ℃, high temperature strength two times greater than the F4 and F4 excellent adhesion and heat sealing properties: melting point, non-wetting with any object. Above the melting point, and F4, the metal has a good adhesion. And self adhesive (heat seal) is not sticky, water fight, fight oil: water contact angle θ = 115о electrical reliability, high insulation 60HZ-60MHZ high and low dielectric constant viscosity at 2.1. www.ptfessd.com even surface due to diving and damage, it does not produce conductive tracks. Volume resistivity> 1018ΩM surface resistance> 2 * 1013Ω arc resistance> 165 seconds without leakage weather resistance: prolonged exposure to ozone can, corrosion resistance under the sun: only the high temperature element fluorine, alkali metals and it works on all other concentrated, dilute mineral acids, bases, esters had no effect
