HALOGEN FREE POLYMER COMPOSITIONS AND TAPES AND METHOD OF MAKING SAME.

摘要

Provided is a composition having a halogen-free polymeric material, a halogen-freeflame retardant, and a coupling agent. Also provided is a method of making a tapecontaining 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 tapeis 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 10.34Mpa (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 least90% of an original average dielectric strength after the tape is conditionedfor 96 hours in air with a temperature of 23.0 C and a relative humidity of96%.
