W. R. Grace and Milliken combine catalyst and additive technologies

12/10/2014

W. R. Grace & Co. and Milliken & Co. have teamed up to offer polypropylene (PP) manufacturers new and differentiated resin portfolios featuring enhanced clarity, cleanliness, processability and mechanical performance.

Grace's CONSISTA C601 PP catalyst, the first sixth-generation non-phthalate-based catalyst and a drop-in solution for the UNIPOL PP process, reportedly enhances performance and processing of homopolymers, random copolymers and impact copolymers. With random copolymers made from CONSISTA catalysts combined with Milliken's Millad NX 8000 clarifier, customers can achieve additional benefits such as glass-like transparency and faster cycle times.

"Combining our CONSISTA catalyst with Milliken's innovative additives yields results that are much more than the sum of these two technologies," said Ella Chen, UNIPOL PP Licensing global market director. "Together, our solutions address a broad spectrum of resin manufacturers' requirements, from higher melt flow to lower-temperature processing for cycle time reduction. Major manufacturers are already taking full advantage of the synergies between our two offerings to produce new polypropylene grades that target consumer demand for clarity, safety and sustainability. This collaboration is another example of our longstanding, successful partnership with Milliken."
