2. Blending to improve the hardness of plastics


An improved method of plastic blending is to blend a high hardness resin in a low hardness resin to increase its overall hardness. Common blending resins are: PS, PMMA, ABS and MF, etc. The resins to be modified are mainly PE, PA, PTFE and PP.


3. Composite improved plastic hardness


The method of improving the hardness of the plastic composite is to combine a high hardness resin on the surface of the low hardness plastic product. This method is mainly suitable for extrusion products such as plates, sheets, films and pipes. Commonly used composite resins are PS, PMMA, ABS and MF.


4. Plastic surface hardness improvement


The method refers to only improving the hardness of the appearance of the plastic product, and the hardness inside the product is unchanged. This is a low cost hardness improvement method.


This modification method is mainly used for housings, decorative materials, optical materials, and daily necessities. This modification method mainly includes three methods of coating, plating and surface treatment.
