FEP, PFA Heat Shrink Tube
【 特 征 Features】
耐高低温：FEP-200 - 200°C，PFA -200 - 260°C
不粘性，拼水、拼油：水接触角θ=114°
不燃性：空气中不会燃烧（氧气指数>95vol%）
耐蚀性：只有高温下元素氟，碱金属与他起作用，对其他所有的浓、稀无机有机酸、碱、酯均无作用。
电可靠性，高绝缘性：60Hz-60MNz高温下介电常数均为2.1，即使表面因跳火而受到伤害，也不会产生导电轨道。
体积电阻：>1018Ωm
表面电阻：>1013Ω
耐电弧>165秒，不漏
低磨擦：动磨擦系数：0.2-0.3
A wide range of practicable temperature
FEP-200 - 200°C，PFA -200 - 260°C
Not adhesive, working together with water and oil
Water contact angleθ=114°
Not flammable
It won't inflame in the air. (Index of Oxygen>95vol%)
Corrosive resistance
Element F only acts on alkali metals in high temperature. It doesn't work with other thick or thin acid, alkali and ester.
Dielectric Property, High Insulated
60Hz-60MNz dielectric constant is 2.1, No matter in high or low temperature.
There won't bu electric conduction even though the surface which is damaged by flashowe.
Volume resistance>1018Ωm
Sheet resistance >1013Ω
Arc resistance >165 seconds leadproof
Low friction
Coefficient of Dynamic friction:0.2-0.3
