Description
Polyimide film tape utilizes a specialized pressure-sensitive adhesive (PSA) and base polyimide film, providing robust thermal stability from –269°C up to 260°C. It boasts superior dielectric strength, ensuring insulation in high-voltage environments. Its resistance to flames and chemicals further enhances its applicability in hostile conditions often encountered in electronics, aerospace, and automotive sectors. Several versions conform to UL 94V-0 flame retardancy and demonstrate low outgassing, supporting use in cleanroom and aerospace environments. This tape consistently withstands thermal cycling and maintains dimensional stability over prolonged periods, making it ideal for modern manufacturing and repair processes.
