Intertape® – Electrical adhesive tapes Intertape® 4118
Intertape® 4118 is a Kapton® tape with silicone adhesive.
DuPont™ Kapton® polyimide backing and silicone adhesive offers outstanding thermal resistance and excellent electrical insulating properties. This tape is used where toughness, puncture resistance, extreme resistance to heat, and flame retardance are required. Operating temperature range is -60 °C (-76 °F) to +260 °C (500 °F).
Application
Used on gold fingers for protection in wave soldering. Is being used as ground barrier and phase insulation in high performance torroidal coils. Also used as an outer wrap on small bobbin wound coils and on form wound coils for traction motors.
