ACR Impact Modifier Processing Aid is multi-functional acrylic copolymer designed for rigid PVC. It combines impact modification and processing aid performance in one powder. It boosts low-temperature impact strength of PVC, meanwhile accelerates resin fusion, raises melt strength and stabilizes extrusion process. This dual-function additive reduces formulation complexity, suitable for PVC window profile and PVC pipe fitting. It maintains good weather resistance and dimensional stability for out
Product DetailsChemical IdentityProduct Name: ACR Impact Modifier Processing Aid Chemical Type: Acrylic copolymer dual-functional impact & processing additive Physical Form: White free-flowing powder Core Feature: Acrylic copolymer with impact modification and processing promotion for PVC window profile and pipe fitting
Key Performance & TDSThis dual-purpose acrylic copolymer improves not only melt fusion and melt elasticity like standard ACR processing aids, but also enhances the impact toughness of rigid PVC. It prevents brittle fracture of PVC window profile and pipe fitting under impact and low temperature conditions. It optimizes melt flow behavior during extrusion and injection molding, reducing surface defects and improving product gloss. It has excellent compatibility with PVC resin, CaZn / tin stabilizers, lubricants and calcium carbonate fillers. It retains outstanding weather resistance, resisting aging and yellowing for long-term outdoor service. Fine powder achieves uniform dispersion in high-speed mixing, avoiding agglomerates and product defects. It simplifies formula design by combining impact modification and processing aid into a single additive.
