Pp filler masterbatch is a granular material made of polypropylene (PP) as the carrier resin by adding a certain prcportion of cattium carbonate and other auxiliary additives, through mixing, meltextrusion. pelleting and other processes.

The cost of pp filling masterbatch is much lower than that ofPP resin material, and the amount of pure PP can be reduced by adding masterbatch, which can significantly reduce the cost of raw materials under the premise of ensuring the basic performance of the product. it can also improve the performance of the product, improve the rigidity, hardness and wear resistance; Reduce the shrinkage rate and warpage deformation of the prod- uct and improve dimensional stability. The addition of masterbatch can adjust the fluidity of the PP melt, reduce the internal stress during the mold- ing process, and facilitate processing and molding, such as injection mold- ing, extrusion,etc.

PP filled masterbatch is widely used in the production of polypropylene products, such as turnover boxes,plastic patlers, daily necessities, auto parts,etc.
