But PPO molecule chain rigiditys are larger, and notch shock is very sensitive, simultaneously because its melt viscosity higher, prevents it from being molded
Shaping, therefore significantly limit its application.
Because polyphenylene oxide is armorphous and nonpolar resin, nylon is crystal type and polar resin, while the two has breach
Sensitivity, the poor defect of impact property, therefore, how to produce one kind can either comprehensive polyphenylene oxide and semi-aromatic nylon each
Advantage can overcome the alloy material of the poor defect of the shock resistance of the two just to turn into problem demanding prompt solution again.
