When using PI tape on curved surfaces, choose thin, conformable films with suitable adhesive types and ensure environmental stability for long-lasting performance.
Surface treatment, such as corona, plasma, or primer coating, boosts PI tape’s adhesive stability, ensuring strong, lasting bonds in high-heat, high-humidity, and high-stress environments.
PI tape can be used for copper coverage during manufacturing but may affect high-frequency signals if left on active RF components. Thin or RF-grade polyimide tape is recommended for minimal impact.
Polyimide (PI) films stand out as exceptional materials, boasting remarkable properties. In terms of heat resistance, they can maintain stability in extreme temperature ranges from -269°C to 280°C for prolonged periods, withstanding short-term temperatures up to 400°C. This unparalleled high- and low-temperature performance makes them indispensable in harsh environments. Electrically, PI films offer top-tier insulation, effectively blocking current flow to ensure equipment safety. Their mechanical strength, featuring high tensile strength and modulus, coupled with abrasion resistance and impact durability, ensures structural integrity in complex conditions. Additionally, their exceptional chemical stability resists most organic solvents, acids, alkalis, and oils, preserving performance in corrosive environments. These attributes position PI films as critical materials across diverse industries.
PI films, known for their exceptional high-temperature resistance, mechanical strength, and electrical insulation, have become indispensable in electronics, aerospace, automotive, and renewable energy sectors. In electronics, PI films serve as substrates for flexible printed circuits (FPCs), enabling devices to withstand bending and twisting while maintaining electrical stability. Aerospace applications leverage their resistance to extreme temperatures (-269°C to +400°C) and radiation, protecting critical components in spacecraft and missiles. Additionally, PI films’ low thermal expansion and excellent chemical resistance make them ideal for motor insulation in electric vehicles and as barriers in solar panels. As a "golden film," PI’s performance has revolutionized high-tech industries, driving innovation and reliability in cutting-edge applications.
