Copolymers for Injection Molding
Milliken & Company has announced that it will launch two performance-enhancing new materials at NPE 2018, held May 7-11 in Orlando, Fla. The first material is a unique performance modifier for injection-molded polypropylene (PP) impact copolymers (ICPs). The second is a new member of Milliken’s Hyperform® HPN family of nucleating agents, which is specifically designed to maximize stiffness in PP ICPs. Both of these novel technologies will significantly change the way PP ICPs perform, particularly regarding impact strength, stiffness and melt flow. By improving the physical properties of post-consumer recycled resins, the new performance modifier allows converters to take greater advantage of their cost and sustainability benefits.

Clearer, Better, Faster
Milliken offers advanced technologies that address the plastics industry’s need for improvements in material clarity, performance and processing.
- Clearer: NX™ UltraClear PP, which is polypropylene clarified with Milliken’s Millad® NX™ 8000 clarifier, enhances the aesthetics, clarity and quality of PP applications. This high-performance technology encourages the broader use of PP, which combines high temperature resistance with glass-like transparency, light weight and easy recyclability. Milliken’s ClearTint® colorants, also to be featured at the booth, are FDA compliant and provide bright, rich and transparent colors to PP applications.
- Better: The new performance modifier improves the impact resistance and melt flow properties of PP ICPs, enhancing their strength and support for cost-effective downgauging, respectively. The new Hyperform HPN nucleator maximizes stiffness, which also enables thinner gauges. Milliken’s other Hyperform HPN nucleating agents for PP and polyethylene (PE) will also be showcased at the event. These materials provide an excellent balance of impact resistance and stiffness performance, as well as improved shrinkage control to reduce warpage. Also on display, ClearShield® UV absorbers for polyethylene terephthalate (PET) provide exceptional UV protection and improved color stability to extend the shelf life of foods and beverages, personal care products and household cleaners.
- Faster: Millad NX 8000 clarifier enhances productivity by enabling broader use of PP, whose lower processing temperatures increase production speeds in injection molding. Similarly, Hyperform HPN nucleating agents’ ability to create a unique crystal orientation in PP and PE shortens cooling times and contributes to higher productivity. Both of these technologies and the new performance modifier are suitable for PP grades with high melt flow, which also facilitates faster cycle times.
Milliken’s expanding array of products add significant value to PP, PE and other popular materials used in the packaging, housewares, furniture, industrial, automotive and appliance industries. Representative applications from these sectors will be on display, demonstrating the benefits of Milliken’s technologies.
