Heat Resistant Insulation Kapton PI Polymide Film
Descprintion
Heat Resistant Insulation Kapton PI Polymide Film is excellent insulation material.The color is yellow/amber/gold and transparent/colorless, Matte black/glossy black ect. The density is 1.39-1.45, Polyimide Film has excellent resistance to high and low temperature, electrical insulation, adhesion, radiation resistance, resistance to medium, It can be used in the temperature range of -269℃ ~ 280℃ for a long time, can reach 400℃ in a short time.The tensile strength is 200MPa at 20℃ and greater than 100MPa at 200℃.Especially suitable for flexible printed circuit board substrate and various kinds of high temperature electrical insulation materials.
PI Film advantages:
(1) excellent heat resistance.2) excellent mechanical properties.(3) good chemical stability and moisture and heat resistance.(4) good radiation resistance.(5) good dielectric performance.
These properties are stable over a wide range of temperatures and frequencies.In addition, polyimide also has the characteristics of low temperature resistance, low expansion coefficient, flame retardant and good biocompatibility.Polyimide can be widely used in many fields due to its excellent comprehensive properties and diversity in synthetic chemistry.
Application industry：
Heat Resistance Pi Film is widely used in space technology, F motor, H motor, electrical insulation, FPC (flexible printed circuit board), PTC electrothermal film, TAB (pressure sensitive adhesive tape base material), aerospace, aviation, computer, electromagnetic wire, transformer, audio, mobile phone, computer, metallurgical, mining the electronic components industry, automobile, transportation, atomic energy industry and electronic industry, etc.
