Acrylic Processing Aid or called ACR, It is a thermoplastic graft polymer born from the emulsion polymerization of methyl methacrylate and butyl acrylate. Characterized by its core-shell structure, ACR boasts a molecular weight typically ranging from 1 to 8 million (weight average molecular weight) and a density between 1.05 and 1.20 g/cm³.
Key Benefits of Acrylic Processing Aid
ACR used in pvc products to promote faster fusion, increases melt strength, enhances extensibility and improves melt homogeneity.
Significantly increases the surface quality of PVC products,offering excellent wall-thickness control and good thermoforming capabilities .Accelerate fusion rate, increase productivity and decrease processing temperature.
Excellent clarity and surface quality for end-use products, superior fusion promotion for rigid and soft PVC.Increased output rates and improved production efficiency.
Selection of different molecular weights
Low Molecular Weight: Ideal for applications requiring transparency, such as transparent films and sheets.
Medium Molecular Weight: Suited for general PVC products, including pipes, fittings, and profiles.
High Molecular Weight: Designed for foam products like PVC foam boards, sheets, and Wood-Plastic Composites (WPC).
