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.
