Product Description:
Polynylene oxide (PPO) called polynylene ether b. is one of the five generic engineering world. It has a rigid, high heat resistance, flame retardant, high strength and exnt electrical properties, etc.
In addition, PPO also has a wear-resistant, non-ant to pollution. PPO [2] of the dielectric constant and dielectric loss in engineering plastics is one of the smallest breeds, almost independent of temperature, humidity.
