The kapton tape, also known as polyimide tape or gold finger tape, is a high-temperature tape made from a polyimide film base coated with high-temperature-resistant silicone. It offers excellent heat resistance, insulation, chemical resistance, and mechanical strength, making it widely used in electronics, electrical appliances, aerospace, and other fields.
Features:
High-Temperature Resistance:
PI tape can withstand extended use in high-temperature environments ranging from 200°C to 300°C, with some grades even capable of withstanding higher temperatures. It is an ideal choice for insulation and protection in high-temperature environments.
Insulation:
It offers excellent electrical insulation properties and is commonly used for electronic circuit protection in applications such as FPC (flexible printed circuit) manufacturing and motor winding.
Chemical Resistance:
It withstands most chemical reagents and solvents, ensuring reliability in challenging environments.
High Strength:
It exhibits excellent toughness and tear resistance, making it less susceptible to breakage in automated production lines or during high-speed lamination processes, improving production efficiency.
Applications:
Electronic and electrical industry: PI tape is used as a backing material for FPC and TAB (pressure-sensitive adhesive tape), protecting circuits and providing insulation.
Aerospace: Used in the manufacturing and maintenance of spacecraft and aircraft components.
Automotive: Used for insulation and securing automotive electronic equipment and wiring harnesses.
Other Industries: Used in motors, transformers, audio equipment, mobile phones, computers, etc.
