PPO Chinese name is also called polyphenyl ether b, is one of the world's five general engineering plastics. It has the advantages of large rigidity, high heat resistance, flame resistance, high strength and excellent electrical performance. In addition, PPO also has the advantages of wear-resistant, non-toxic, and pollution resistance.
Characteristic：
Good dimensional stability, high rigidity, solubility resistance, good electrical properties, high heat resistance, low shrinkage.
