The availability of scrap poly(ethylene terephthalate) (PET) from post‐consumer bottles is increasing as the post‐consumer collecting systems are becoming more usual in daily life. PET is well known as a high‐performance engineering thermoplastic because of its good thermal stability, chemical resistance, and excellent mechanical properties. Many efforts have been carried out to use this material in housings of electronic applications. However, the flammability of PET is a shortcoming in some of these applications. In this study, our attempt is to incorporate a non‐halogenated flame retardant, in form of a phosphorus‐containing compound, together with a commercial glass fibre grade to achieve UL94 test V‐0 rating for PET. An investigation of thermal stability and flammability (HDT, UL94 V‐test) and mechanical (tensile, flexural and impact tests) properties of glass fibre filled PET samples is reported as a function of fraction of flame retardant. This work shows the influence of the filler content and the interfacial filler/matrix adhesion on the flame retardant and the mechanical properties.
