cooling masterbatch

In the past, the cooling masterbatch was mainly used in the spinning of polypropylene. Because the molecular weight and viscosity of the polypropylene resin used at that time were higher, the spinning temperature could reach more than 300 ° C before normal production, it is easy to make additives, pigments and other decomposition (currently there is a production of high melt index polypropylene resin for spinning)
