FLAME-RETARDANT, GLYCOL-MODIFIED POLYETHYLENE TEREPHTHALATE FILM

摘要

The present invention relates to a synthetic resin film having excellent flame retardancy, and more particularly to a glycol-modified polyethylene terephthalate (PET-G) film having excellent flameproof and low-smoke-emission properties, which is molded from a PET-G composition containing glycol-modified polyethylene terephthalate (PET-G) as a main component, a flame retardant, a lubricant and a processing aid. The resin composition contains the flame retardant, the processing aid and the lubricant in amounts of 20-35 parts by weight, 0.5-5 parts by weight and 0.1-1.5 parts by weight, respectively, based on 100 parts by weight of the PET-G. The film having flameproof and low-smoke-emission properties has a char area smaller than 30 D, which is a proposed standard for thin sheets in the KOFEIS 1001 standards. Also, it has an excellent smoke density suppression effect. The PET-G film is useful for building interior/exterior materials, flooring materials, adverting materials, car/aircraft interior materials, other decorative materials, etc.
