PELLETIZED ADDITIVE BLENDS WITH HIGH EXTRUSION THROUGHPUT RATE

摘要

A melt extrusion process for producing pelletized 100% additive blends using additives with lower Hausner ratio and larger particle size with granular form, compared to powder form of additives; also additive blends produced by such process. Extrusion throughput rate is increased using granular additive particle form with lower Hausner ratio than that of powder form. The productivity and efficiency of the process is enhanced by using a larger particle size of additives. Additive blends and polymer stabilization agent blends can be added in post-polymerization processes in resin manufacturing plants to enhance the processing and performance properties of polymers.
