Polyimide Tape 0.05mm x 20mm
Polyimide Tape 0.05mm x 20mm is a high temperature PI film adhesive tape designed for battery insulation, PCB protection, electronics assembly, and temporary masking in heat-resistant industrial processes. It combines stable handling, silicone adhesive performance, dielectric insulation, and controlled clean removal in suitable masking applications. In the market, this type of product is also commonly searched as Kapton tape for battery insulation and electronics protection.
What is Polyimide Tape 0.05mm x 20mm?
Polyimide Tape 0.05mm x 20mm is a pressure-sensitive tape made from polyimide (PI) film backing coated with silicone adhesive for demanding industrial and electronic applications. It is commonly used where high temperature resistance, electrical insulation, medium-width masking, and process stability are required. Compared with thinner masking tapes, this 0.05 mm PI film adhesive tape provides more stable handling for battery insulation, PCB masking, electronics protection, and elevated-temperature assembly processes. Many buyers also search for this type of material as Kapton tape when sourcing battery insulation tape or high temperature PI tape.
