Durability evaluation method of flame retardant recycled materials using polypropylene parts collected from waste home appliances

Abstract

We are promoting technological development of “highly functional” recycled material as an initiative to increase usage of recycled materials using plastic parts collected from waste home appliencies.

Among them, we developed a new durability evaluation method of frame retardant polypropylene recycled materials because the conventional method of measuring Oxidation Induction Time could not be applied.

This study is concerned with recycled polypropylene materials using collected parts from waste home appliencies that satisfy both the performance required for home appliencies and flame retardancy.

Among the developed technologies, an overview is reported especially on the durability evaluation method that takes into account the amount of additives that accelerate oxidative degradation of polypropylene and variations of waste materials.
