8mm Koptan High-Temperature Resistant Tape (30 Meter) red digital display 30ms/115VAC at full load HoldKoptan tape is a polyimide film first developed by DuPont in the 1960s. It remains stable at an extremely wide range of temperatures from 269C to 260C and has been an industry standard due to its excellent electrical, thermal, chemical and mechanical properties. This enables the film to withstand extreme temperatures, vibration, and other demanding environments. This Koptan 8mm wide High Temperature Resistant Tape for 3D Printers is a polyester film
