Cooling masterbatch can reduce the molecular weight of PP, thereby reducing the processing temperature of PP. Its main component is peroxide.At present, the application scope of cooling masterbatch has been expanded, and it has become a commonly used additive for some PP modification production companies, especially in the production of high-flow PP (such as large thin-walled storage barrels in supermarkets).

Cooling masterbatch is mainly used to reduce the processing temperature in the production of PP (polypropylene) spinning and plastic products, to improve the fluidity of polypropylene, so as to improve the processability and reduce energy consumption.

The best effect is achieved during the spinning process of PP long and short yarns. It is also widely used in the production of PP blown film, textile bags, monofilament, injection molding, PP pipe and other products.
