Material plastic PPS+PPO/GF is a kind of special engineering plastics, known as the "new plastics for the jet age", with excellent heat resistance, corrosion resistance and self-extinguishing and mechanical stability, is the sixth engineering plastics, the amount of special engineering plastics is the most extensive. PPS/PPO alloy has the advantages of PPS and PPO, such as high temperature resistance, chemical corrosion resistance and high mechanical and electrical properties. It also overcomes the shortcomings of PPS, such as brittle melt, low melt viscosity, difficult injection molding flash overflow, and PPO's resistance to solvents and high melt viscosity.
