Problems solved by technology

[0002] PPO (polyphenylene ether) resin is an amorphous material with excellent heat resistance, good dimensional stability, excellent electrical insulation and excellent creep resistance. It is one of the most important engineering plastics, but its impact performance is relatively low. Poor, and poor fluidity is difficult to process, which greatly limits its application in some fields
PA66 resin is a crystalline material with good fluidity and easy processing, but it is easy to absorb water, has poor dimensional stability and poor heat resistance
