Cooling masterbatch also known as molecular weight distribution regulation masterbatch, it can adjust the size of the molecular weight of polypropylene (that is, can adjust the melt flow index of polypropylene), but also can adjust the molecular weight distribution of polypropylene, so that the molecular weight distribution of polypropylene narrower, foreign polypropylene manufacturers, in the process of polypropylene production selectively add cooling masterbatch, and domestic manufacturers, in order to reduce production costs, Without cooling masterbatch, the method of hydrogen partial pressure is used to adjust the melt index. This method cannot remove the high molecular weight end of polypropylene, which is why the processing performance and product quality of imported and domestic polypropylene with the same brand and melt index are very different. The cooling masterbatch provided by our company can greatly improve the deficiency in this respect.
PP cooling masterbatch, mainly used to reduce the processing temperature of PP(polypropylene) spinning and plastic products production, improve the flow performance of melt, also has plasticizing and antistatic properties, but also widely used in PP material blown film, textile bags, polypropylene coarse, fine denser length, short filament, monofilm, injection molding, pipe, plate, home appliances and auto parts and other products production, It is an ideal functional addition masterbatch in PP processing.
