PSA 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 silicone glue. PSA adhesive tape has become perfect class- H insulating material.

NOTE: PSA is abbr. of polyimide film silicone adhesive

Characters:

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

* Excellent heat resistance,used as class-H insulation and can work for 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;

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

* Different thickness and width to meet customers' specific requirements.

NOTE: normal color of this material is amber. Please contact us for color requests of: black,green,red,transparent,etc.
