Polyimide Tape 0.12mm x 50mm
Polyimide Tape 0.12mm x 50mm is a high temperature PI film adhesive tape designed for electrical insulation, heavy-duty masking, industrial protection, and high temperature process support. It combines a thicker structure, 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 electrical insulation and high temperature industrial use.
What is Polyimide Tape 0.12mm x 50mm?
Polyimide Tape 0.12mm x 50mm is a pressure-sensitive tape made from polyimide (PI) film backing coated with silicone adhesive for demanding industrial and electrical applications. It is commonly used where thicker insulation support, high temperature resistance, wider coverage, and process stability are required. Compared with thinner PI tapes, this 0.12 mm polyimide film tape provides a stronger structure suitable for electrical insulation, heavy-duty masking, converted protection parts, and elevated-temperature manufacturing. Buyers also search for this material as Kapton tape when sourcing thick high temperature insulation tape.
