Engineering Thermoplastics
PPO/PPE Standard — Polyphenylene Oxide / Polyphenylene Ether Standard
PPO/PPE is amorphous and typically supplied as blends with polystyrene or other polymers to improve processability. It offers excellent hydrolytic stability, good dimensional stability, low creep, and outstanding electrical insulation properties over a wide range of temperatures and frequencies.
