coil insulation Insulating Circuit Board black Kapton Tape double sided polyimide high temp tape

Insulating Circuit Board black Kapton Tape Polyimide Tape double sided polyimide tape

Product introduction

Polyimide tape ,commonly known as high temperature tape and gold finger tape, is made of polyimide film coated by pressure sensitive adhesive. Polyimide tape is divided as PI silicone tape and PI acrylic tape by the type of adhesive. In general PI tape is in black and tawny colors.

Product features

With the backing of soft polyimide film, PI tape is excellent in electrical insulation and heat resistance. Generally, the polyimide film

can withstand temperatures above 400 ℃. If coated with silicone pressure sensitive adhesive, the overall tape temperature resistance is up to 280 ℃.When coated with acrylic pressure sensitive adhesive, the tape is characterized in excellent viscosity and weatherability.

Product application

PI silicone tape is mainly used in resisting high temperature or applications that require high initial adhesion, such as H class motor and wrapping transformer coil insulation, fixing the ends of heat-resistance coil, the protection of thermal resistance, capacitors and wire tangles, bonding insulation under high temperature, temperature resistance protection of gold finger PCB board and electronic components during SMT and external wrapping of polymer lithium batteries. PI acrylic tape is often used for PCB board insulation, fixing and binding up the wiring harness , wrapping within the transformer coil layer and the outer layer as well as lithium batteries external insulation.
