PSA Adhesive Tape is a pressure- sensitive tape made of heat- resisting polyimide (PI) film coated by silicone adhesive. Due to excellent mechanical, dielectric strength and heat resistance in PI film and reliable heat-resistance in silicon glue , AI adhesive tape has become perfect class- H insulating material

* 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℃ but short time at 260℃;

* Good flexibility, better tear resistance and excellent workability, and can be glued on the different-sized workpieces;
