Processing Aid Acr401 Application: Plastic

Processing Aid ACR401 is 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 PVC products by reducing foam density and increasing impact strength, surface quality, and uniformity. ACR-401 modifier promotes a wide processing window, providing the flexibility to limit the number of processing aids for various applications.

Product Benefits and Application
Promote 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-401 has been used in weatherable applications and is widely used in PVC building products.
ACR-401 is mainly used in PVC profiles, foam pipes, foam profiles, foam sheets, wood-plastic composites, etc.
