2, the plastic surface treatment to improve the hardness of the exterior of the plastic products, the internal hardness of the products remain unchanged. This modified plastic modification method is mainly used for shells, decorative materials, optical materials and daily necessities. This plastic modification method mainly includes coating, plating and surface treatment of three methods.
2, through the plastic **** mix to improve the overall hardness of modified plastics, common **** mixing resins are: PS, PMMA, ABS and MF, etc., need to modify the resin is mainly for PE, PA, PTFE and PP.
3, through the plastic composite to improve the hardness, that is, in the low hardness of plastic products on the surface of the composite layer of high hardness resin. This method is mainly suitable for extruded products, such as plates, sheets, films and tubes. Commonly used composite resin for PS, PMMA, ABS and so on.
