Isotropic shrinkage
Polypropylene is a semi-crystalline polymer which shrinks after molding. The nucleator influences the absolute shrinkage and the ratio of machine/mold direction shrinkage to transverse direction shrinkage (MD/TD shrinkage). Our solutions impart excellent isotropy, resulting in reduced warpage and stable dimensions in the end-product. As well as enhancing quality, they help to reduce waste and make production more efficient.
