Next-Generation Catalyst and Additive Technologies from W. R. Grace and Milliken Combine to Deliver Exceptional Results to PP Producers


SPARTANBURG, S.C. – W. R. Grace Co. and Milliken Company today announced that their advanced technologies, used synergistically, are enabling polypropylene (PP) manufacturers to develop 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 widely used UNIPOL® PP process, enhances performance and processing of homopolymers, random copolymers and impact copolymers. With random copolymers made from CONSISTA® catalysts combined with Milliken's next-generation Millad® NX™ 8000 clarifier, customers can achieve additional benefits including 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."



Several UNIPOL® PP process licensees are leveraging the Grace and Milliken technologies to produce resins that meet the stringent requirements of their customers.



CONSISTA® C601 catalyst imparts a market-leading balance of impact and stiffness to enable lightweight, thin-wall designs. The technology enables the production of random copolymers with improved taste and odor performance for food contact applications. The CONSISTA® catalyst enables

faster cycle times by increasing melt flow rates, while its broader molecular weight distribution improves the mechanical and processing attributes for a variety of applications.



When new generation Millad NX 8000 clarifier and CONSISTA® catalyst are combined in random copolymers with a high melt flow rate (MFR), they enable up to a 36 percent reduction in haze over previous generations to provide a high transparency, bright appearance and high gloss in molded parts. Simultaneously, the Milliken additive also allows PP to be processed at significantly lower temperatures of 190C to 200C, a reduction of up to 40 degrees compared to less-advanced clarifiers. These cooler temperatures shorten cooling times and increase productivity by facilitating mold release.



Another combined benefit of the Grace and Milliken technologies is enhanced sustainability.



"Grace's technologies set the standard for polypropylene catalyst innovation and we are pleased that our next-generation clarifying agent adds significant value," said Wim Van de Velde, global marketing director, Milliken & Company. "By adding our Millad NX 8000 to resins catalyzed with CONSISTA® catalyst, manufacturers can gain even greater aesthetic, processing and performance advantages."
