The modified plastic parts can not only achieve the strength properties of some steels, but also have a series of advantages such as light weight, rich colors, and easy molding. Plastic blending modification refers to a modification method in which one or more other resins (including plastics and rubbers) are added to a resin to change the properties of the original resin. The modified plastics not only have the advantages of traditional plastics, such as low density and corrosion resistance, but also have greatly improved physical and mechanical properties. A stirring device is required during the processing.
