Description
A thermoplastic polymer made by the oxidative condensation of 2,6-dimethyl phenol. Polyphenylene oxide, PPO, is a good electrical insulator. It is a noncrystalline polymer that can crack when exposed to UV light or halogenated solvents. Modified PPO is made by blending PPO with 50% by weight polystyrene. Modified PPO is used as a structural foam in appliances and electrical housings.
