Intertape® 4118 is a Kapton® polyimide film electrical adhesive tape. 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. Measured against maximum temperature criteria (VDE 03340, DIN 40633) this tape can withstand high temperatures for limited periods of time (250°C = 1.000 hours, 350°C = 10 hours). Flame retardant according to UL510.
