Hyperform® HPN® 20E by Milliken is a high performance nucleating agent for polypropylene. It offers excellent stiffness/impact balance, unique isotropic shrinkage and superior CLTE performance. It has excellent nucleation performance to maximize processing speed, consistent processing, cycle time reduction (more caps/minute) as well as improved quality-less defects such as sink marks. Exhibits better dimensional stability. It is used in automotive, appliances, pipe extrusion and closures. Hyperform® HPN® 20E is suitable for processing by injection molding, thermoforming, extrusion blow molding, rotomolding and blown film extrusion.

BRUGGOLEN® TP-P1401 by Brüggemann acts as a highly effective nucleating agent for polyamides. It can be processed at elevated temperatures, enables reduced overall cycle time and consequent higher production rates. It supports the formation of morphology with very small, homogeneously distributed spherulites. It provides improved mold release and dimensional stability of the finished product. It improves the mechanical properties (increased tensile strength and stiffness) and significantly enhances the surface appearance of reinforced polyamides. Suitable for injection molding and compounding on twin screw extrusion machines. BRUGGOLEN® TP-P1401 is easy to dose and disperse. Recommended dosage level is 1.0 to 2.0% depending on the polyamide and the desired properties of the finished parts. The shelf life of the grade is at least 12 months under (closed, dry, 25°C) standard conditions.

Hyperform® HPN® 900ei by Milliken is a high-performance additive designed for thin-wall injection molding in polypropylene homopolymers and mini-randoms. It exhibits an excellent balance of physical properties with good stiffness (flexural modulus) and impressive impact performance. It provides a higher heat deflection temperature and an increase in crystallization temperature. Its unique isotropic shrinkage behavior allow dimensionally stable, non-warping PP parts. It reduces haze and the yellowness index, yielding final parts that are cleaner, clearer and more transparent, which can further enhance sustainability by allowing for more inter-material replacement. Hyperform® HPN® 900ei ?is suitable for packaging applications.
