Product Name:(Factory Supply Free Sample)Kapton Polyimide stretch film(Transparent Amber,gold,brown)

BOPI Polyimide film Kapton film(similar to Kapton HN) is achieved by polycondensation of PMDA and ODA in strong polar solvents, through the process of film forming, and then being stretched and Oriented by biaxial during the course of imine at high temperature. BOPI film is a special kind of polyimide film. Because of biaxial orientation process, BOPI film possesses higher physical, chemical, and electrical properties. It is widely used as insulation material in F~H class electric motors, electric locomotive, high temperature cables, backing or cover film of FPCB (flexible printed circuit) applications, aerospace industries and so on.

 

Characters:

* Higher mechanical strength, better dielectric strength with thinner insulation ply;

* Excellent heat resistance ,used as class- H insulation and can work for a long term at

180°C but short time at 260°C;

* Good flexibility, better tear resistance and excellent workability, and can be glued on the

different-sized workpieces;

* Self-sticking and good bonding strength , no removal after stripping off;

* Different thickness and width to meet customers’ specific requirements;
