The subject wants to ask, "can pet and pvc be combined into granulation formula?" ? Of course. According to the query of China Chemical Network, from the perspective of preparing PP alloy, ternary * * * mixed alloy can be prepared with high-density polyethylene and low-density polyethylene and PP. On the joint surface of pvc and pet, the surface properties can be changed by fire, flame spraying, plasma treatment and other methods to synthesize granulation formula and increase adhesion, so PET and PVC can synthesize granulation formula.
