PVC plastic granules are granules prepared by mixing, kneading and extrusion with polyvinyl chloride as the base resin, adding stabilizers, plasticizers and inorganic fillers such as calcium carbonate, additives and lubricants. Factors affecting the brightness of PVC plastic pellets cable material: the lower the degree of polymerization of PVC, the brighter the surface; the finer the calcium carbonate particle size, the brighter the surface; plasticizer: the straighter and longer the molecular chain, the brighter; Faster ones are also brighter; technologically, those with high extrusion temperature are brighter than those with low temperature, and those with good mixing effect are brighter than those with poor mixing effect.
