Through the interaction between the components, the polyphenylene ether composite material ...
Embodiment 1
[0062] 65 parts of polyphenylene ether, 5 parts of wholly aromatic liquid crystal polyester resin (Jiangsu Water Special Material Manufacturing Co., Ltd.), and 30 parts of glass fiber were dried at 130° C. for 6 hours. Put the dried polyphenylene ether, liquid crystal polyester resin and glass fiber into an automatic mixer to mix evenly, then put them into a twin-screw extruder for melting and mixing, and then produce polyphenylene ether through extrusion, drawing, cooling, and granulation Composite material.
