48mm Koptan High-Temperature Resistant Tape (30 Meter) Nickel Coated The gearbox is completely sealedKoptan 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 48mm wide High Temperature Resistant Tape for 3D Printers is a polyester film
