Polyimide Film Adhesive Tape

NAME:Polyimide Film Adhesive Tapes  ID:Polyimide Film Series Supplier
DETAILS:

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 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;
* 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.

Storage:
Packed in cartons and sealed in plastic film bag; Keep dry at room temperature.
The shelf life is 12 months.
Applications:
PSA tape is widely used in ground, phase, layer insulation, and coils wrapping for class-H electrical machines and
 transformers, wrapping of coils end for common electrical machines and appliance and other sticking insulation in high
 temperature condition; also in PCB wave soldering, protection cover of hot air leveling and other  bonding wrapping
under high temperature and corrosion conditions.
