Specialized high-temperature adhesive rolls, fiberglass reinforcement, and copper EMI shielding solutions ready for global distribution.
Polyimide (PI) film tapes—commonly termed Wide Kapton Tape when converted to widths exceeding 500mm up to 1000mm—represent the pinnacle of dielectric insulation, mechanical endurance, and thermal endurance. Manufactured through polycondensation of aromatic dianhydrides and diamines, our high-precision polyimide films maintain molecular stability across thermal extremes from -269°C to 260°C (with transient spikes to 400°C).
Wide-format polyimide substrates shield silicon wafers during photolithography, wet etching, and physical vapor deposition (PVD). Zero ionic contamination and non-outgassing silicone matrices protect sensitive die regions against ionic penetration.
Critical inter-cell insulation within high-voltage prismatic and cylindrical lithium-ion packs. Wide rolls allow automated wrapping of aluminum cold plates and cell enclosures, preventing dielectric arc transfer up to 7,500V.
Engineered for Multi-Layer Insulation (MLI) blankets across satellite payloads and aerospace harness assemblies. Wide Kapton films exhibit outstanding radiation tolerance, low volatile condensable materials (CVCM), and low total mass loss (TML).
