Milliken Chemical: Eco-responsible polypropylene (PP) additives
Milliken’s Hyperform® HPN-68L hyper-nucleating agent enhances process stability and part quality to simplify PP recycling while Millad® clarifying additives enable PP to be substituted for clear materials such as PET, PVC, PC, PS, SAN, acrylic and glass.
When added to recycled PP, Hyperform HPN-68L increases and levels the Tc of incoming recycle streams. Hyperform also promotes isotropic shrinkage, which is the key to reduced warpage and increased part quality. Hyperform HPN-68L can be added at any point throughout the compounding process. It also accelerates throughput by avoiding the need to constantly recalibrate machine settings for different material properties.
