Kapton Tape, a polyimide film adhesive tape, is a critical material in industries requiring extreme thermal and electrical stability. Kapton Tape is a heat-resistant adhesive tape made from polyimide film, renowned for its ability to withstand temperatures ranging from -269 °C to +400°C (-452°F to +752°F). Its unique molecular structure ensures minimal thermal expansion, excellent dielectric strength, and resistance to chemicals, radiation, and abrasion. Developed in the 1960s, this high-performance tape has become indispensable for aerospace, electronics, and manufacturing sectors.
Key Properties:
Ultra-thin yet durable (typical thickness: 0.03–0.13 mm).
Flame-retardant and UL-listed.
Conforms to irregular surfaces without losing adhesion.
