Polyimide tape

Polyimide tape

2021-05-12

DescriptionPolyimide tape, also known as Kapton tape, PI tape, gold finger tape, etc. It is made of polyimide film as backing and coated with silicone pressure sensitive adhesive. It features excellent electrical insulation properties, high temperature resistance up to 260℃ (500℉), low electrolysis and solvent resistance. It is widely used in high temperature masking and electrical insulation meeting Class H requirements.



Features

∙ Excellent electrical insulation properties

∙ Wide range of temperature up to 260℃ (500℉) 

∙ Good adhesion, easily peeling off and leaving no residue   

∙ Solvent and corrosion resistance       



Application

∙ Mask for protection gold fingers or edge connectors of PCB during the process of wave solder, solder reflow   or solder dip

∙ Fixing of electrical coils in motors, transformers, capacitors and other electrical components

∙ Other high temperature shielding protection, such as 3D printing bed mask, high temperature powder spray   coating, etc.

∙ Other Class H electrical insulation application on various electronic or electrical components assembly
