Milliken and LCY collaborate to launch high-performance polypropylene grade 737U

New grade offers exceptional impact strength, high gloss, and compatibility with in-mold labeling for demanding applications

TAIPEI, Jan. 7, 2026 /PRNewswire/ -- LCY, a leading polypropylene manufacturer and supplier, and diversified global manufacturer Milliken & Company have partnered to introduce 737U, a new high-performance polypropylene grade enhanced with Milliken's DeltaMax™ 5000a additive technology.

737U is designed for injection molding applications such as paint containers, automotive parts, furniture, outdoor gear, and high weight-loading containers. The grade offers excellent rigidity and impact strength, making it suitable for demanding environments and heavy-duty use.

"The launch of 737U marks a significant milestone for LCY and our customers," said Lachosi Lin, Marketing and Sales Executive at LCY. "By working closely with Milliken, we are able to deliver a polypropylene grade that combines outstanding impact strength, high gloss, and efficient processing. This innovation enables us to meet the evolving needs of industries that demand both durability and design flexibility."

737U has been approved by a leading paint brand for use in 3–20L packaging and has demonstrated strong performance in falling and stacking tests. It also supports in-mold labeling, enabling seamless integration of design elements into molded products. Compared to traditional impact polypropylene, 737U offers higher gloss, making it ideal for exterior components in consumer products.

"LCY's 737U grade exemplifies how collaboration and innovation can deliver real-world performance," said Min Shun Cheng, Technical Manager at Milliken. "By leveraging our DeltaMax™ technology, we're helping LCY meet the technical aspects and growing demand for durable, high-gloss polypropylene solutions that also support efficient processing."

LCY was the first customer in Taiwan to adopt DeltaMax™, creating the region's first such commercial grade in 2020. Milliken's DeltaMax™ additive enhances the grade's processing efficiency, enabling faster cycle times and improved moldability.
