Processing Aid ACR401

About Processing Aid ACR401

Processing Aid ACR401is a processing aid based on a high molecular weight acrylic copolymer,the industry standard for foamed PVC, efficiently improving the quality and processability of cellular PVCproducts by reducing foam density and increasing impact strength, surface quality, and uniformity. ACR-401modifier promotes a wideprocessing window, providing the flexibility to limit the number of processingaids for various applications.Physicochemical PropertiesACR-401is White free-flowing powder, bulk density: 0.40-0.55g/cm3, can not be dissolved in water, ethanol, can be dissolved in chloroform. Index/Product Name ACR-401 Appearance White free-flowingpowder Particle size 40mesh(%) 98 volatiles(%) 1.0 Viscosity ()(Ubbelohde Viscometer) 6.0-8.5 Product Benefitsand ApplicationPromote gelation of PVC, Improve hot-melt strength and viscoelasticity, stabilize the microcells generated by blowing agents to achieve the low density and high strength of the foam. Increase the surface quality of PVC products.Better dispersion of additives into PVC, more homogenous melt of PVC, etc.ACR-401has been used in weatherable applications and is widely used in PVC building products.ACR-401ismainly used in PVC profiles, foam pipes, foam profiles, foam sheets, wood-plastic composites, etc.
