POLY(BUTYLENE TEREPHTHALATE) BASED COMPOSITION WITH IMPROVED ELECTRICAL TRACKING RESISTANCE

Abstract: the present invention relates to a thermoplastic polymer composition with a comparative tracking index (cti) rating of 600 v or higher comprising. between 54-96 wt. % of a poly(butylene terephthalate); between 0.5-5.0 wt. % of a pyro/polyphosphate: between 0.5-5.0 wt. % of an alkyl acrylate based copolymer: between 0.5-5.0 wt. % of a polyethylene: between 2.5-30 wt. % of a glass fibre and between 0-1.0 wt. % of a mineral filler: wherein the weight percentages are based on the total weight of the thermoplastic polymer composition. it also relates to the articles formed from the thermoplastic polymer composition, and their methods of manufacture.
