Because additives such as colorants and nucleators in mixed batches of
polypropylene can cause processing issues including shrinkage and
warpage, Milliken developed Hyperform HPN-68L hyper-nucleating agent
to enhance process stability and part quality. When added to recycled
PP, Hyperform allows quick and consistent processing. Hyperform also
promotes isotropic shrinkage, which is the key to reduced warpage and
increased part quality.
