40μm CPI Film Heat Resistant

Product Description
40μm CPI Film Heat Resistant
Heat-Resistant Transparent Colorless Polyimide Film CPI Film



Product Description

Polyimide Film is excellent insulation material.The color is yellow and
transparent,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.

Polyimide 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.





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.
