Fast crystallizing polyethylene terephthalate compositions

摘要

Polyethylene terephthalate molding compositions characterized by rapid crystallization are provided by combining polyethylene terephthalate and a filler or reinforcing agent with a crystallization-rate promoter comprising sodium benzoate and a poly-alpha-olefin such as low density polyethylene. A flame retardant material is provided by the addition of flame retardant additives.
