During the manufacturing process, modified plastic particles may contain a variety of additives, such as fillers, plasticizers, stabilizers, colorants, etc. These additives can improve the mechanical properties, thermal stability, electrical insulation and appearance of plastics. The production process of modified plastic particles involves a series of steps such as mixing, melting, extrusion and granulation of the selected plastic resin with various additives. These particles can be customized according to different application requirements to meet specific performance standards;
