Polyimide Kapton Film | Kapton Polyimide Tape
Kapton® polyimide film is a high-performance insulation film invented and manufactured by DuPont. With its unique chemical structure, it exhibits unparalleled stability under extreme temperature conditions and is widely considered the industry gold standard for flexible insulation materials.
Main Materials: Kapton® polyimide film is primarily synthesized from pyromellitic dianhydride (PMDA) and diaminodiphenyl ether (ODA). The chemical structure of this aromatic polyimide endows it with inherent heat resistance, high strength, and excellent electrical insulation properties.
Functions of Polyimide Kapton Film:
Kapton® Thin films play multiple crucial roles in electronic and electrical systems:
★ Electrical insulation: Serving as a reliable dielectric barrier, isolating conductors and components.
★ Thermal management: Withstanding extreme temperatures, serving as a substrate for heat-resistant layers or thermally conductive interface materials.
★ Mechanical support: Providing a dimensionally stable foundation for flexible printed circuits (FPCs).
★ Physical protection: Protecting sensitive components from chemical, moisture, and abrasion effects.
Key characteristics of Polyimide Kapton Film:
Extreme temperature resistance: Maintaining stable performance over an extremely wide temperature range of -269°C to +400°C, and capable of withstanding short-term temperatures up to 500°C.
Excellent electrical properties: High dielectric strength, low dielectric constant, maintaining good insulation performance even at high temperatures.
Superior mechanical properties: High tensile strength, tear resistance, and flexibility.
Inherent flame retardancy: Meets UL 94 V-0 standards and is non-flammable.
Excellent chemical stability: Resistant to most organic solvents and oils.
Extremely low thermal shrinkage: Maintaining dimensional stability at high temperatures, ensuring long-term component reliability.
Application of Insulation Polyimide Film: PCB Board, SMT Solder Pot,Wave Soldering,Masking for Battery High-Temperature Spray Coating,Insulation Wrapping
