Abstract: Provided is a tape that includes a halogen-free backing comprising a polymeric material; a flame retardant; and a coupling agent; and an adhesive layer located on a surface of the backing. The tape is flame retardant when tested according to Section 4 of Underwriters Laboratories UL 510, Seventh Edition.

Abstract: Provided is a composition having a halogen-free polymeric material, a halogen-free flame retardant, and a coupling agent. Also provided is a method of making a tape containing the steps of forming the previously recited composition into a backing; and applying an adhesive to a surface of the backing to form the tape. When the tape is tested using UL 510 (7th Ed.), it has at least one of the physical properties: an elongation at break of at least 60%; a tensile strength at break of at least 1500 psi; a dielectric strength of at least 1,000 V per mil of tape thickness; an average adhesion strength of at least 0.175 N/mm; and a retention of at least 90% of an original average dielectric strength after the tape is conditioned for 96 hours in air with a temperature of 23.0° C. and a relative humidity of 96%.

Abstract: Disclosed is a multi-layer insulated wire comprising a conductor and one or more insulating layers covering the conductor, wherein the one or more insulating layers are prepared from a composition comprising: (A) 100 parts by weight of a thermoplastic polyester-series resin, and (B) from 1 to 70 parts by weight of an ethylene-series polymer having epoxy and acrylate groups. Also disclosed are a process for preparing the multi-layer insulated wire and electronic devices, such as transformers, comprising the multi-layer insulated wire.
