NINGBO INNO PHARMCHEM CO.,LTD. is pleased to highlight the benefits of its ACR-401 processing aid, a high-quality solution designed to significantly enhance the processing performance of polyvinyl chloride (PVC) resins. ACR-401 is a new generation acrylate macromolecule copolymer produced using advanced polymerization techniques. As a white, fine powder, it serves as an essential auxiliary raw material in the manufacturing of a wide range of PVC products.

The primary function of ACR-401 is to act as an effective plastic modifier and processing aid for PVC. It is composed mainly of methyl methacrylate (MMA) and butyl acrylate monomers, polymerized through a seed emulsion process. This specific composition and manufacturing method result in a product with a special structure that is non-toxic, non-corrosive, has low dust content, and exhibits excellent fluidity. It is also insoluble in water, making it an ideal additive for various PVC applications.

ACR-401 provides numerous advantages during the PVC processing stage. It actively promotes the melting of PVC compounds, leading to a more homogeneous melt. This improved melting efficiency directly contributes to better surface finish and gloss in the final products. Furthermore, ACR-401 enhances the elasticity and strength of the melt, increasing its elongation and overall melt strength. This is particularly beneficial in applications requiring precise shaping and structural integrity.

A key feature of ACR-401 is its ability to improve the cell structure in foamed PVC products. Its ultra-high molecular weight and strong melt strength help to cover bubbles effectively and prevent cell collapse, resulting in a more uniform and fine cell structure. This leads to products with lower density while maintaining excellent physical properties, making ACR-401 especially suitable for PVC foamed thick boards.

The excellent plasticizing ability and melt fluidity of ACR-401 ensure good compatibility with PVC resins, leading to enhanced processing performance and dimensional stability of the final products. Products manufactured using ACR-401 exhibit improved appearance, better mechanical properties, and increased durability.

ACR-401 is widely applicable in various PVC product categories, including rigid, semi-rigid, and even soft PVC formulations, although its primary use is in opaque hard PVC products that benefit from good weather resistance. Typical applications include PVC pipes, profiles, panels, cable sheaths, SPC or WPC flooring, and various building materials such as wall panels, door and window profiles, shutters, and rain gutters. It is also effective in injection molding and blow molding processes.

Technical specifications for ACR-401 include its appearance as a white powder, apparent density typically between 0.3-0.5g/cm³, and a high passing rate through a 40-mesh sieve (≥98%). The volatile component is typically less than 1%, and it boasts high purity. The CAS number for this polymer is 25852-37-3.
