Abstract

The invention discloses a PET electrical insulating adhesive tape, and relates to the field of adhesive tapes. The PET electrical insulating adhesive tape comprises: a base material layer which is arranged to be high-insulation PET; an adhesive layer which is adhered to the upper surface of the base material layer, wherein the adhesive layer is arranged to be acrylics; and release paper which is adhered to the upper surface of the adhesive layer. The PET electrical insulating adhesive tape has a smooth and flat adhesive surface, and the adhesive tape passes environmental certification; imported materials are adopted for production, so that the attaching property and the insulating property are excellent; the permanent adhesion is high, and the anti-warping property is good; and temperature resistance, water resistance and chemical resistance are excellent, the high-insulativity PET material of the base material layer is set to be black and is light-proof, so that the shading adhesive tape is suitable for pasting with shading requirements in the industries of electronics and electric appliances.

Description

technical field [0001] The invention relates to the technical field of tapes, in particular to a PET electrical insulating tape. Background technique [0002] Electrical insulation adhesive tape, with good insulation, flame resistance, voltage resistance, cold resistance and other characteristics, suitable for automotive wiring, wire winding, insulation protection, etc. [0003] Most of the existing electrical insulating tapes are made of soft polyvinyl chloride (PVC) film as the base material and coated with rubber-type pressure-sensitive adhesive.
