1. Enhance melt strength

High molecular weight ACR processing aids have long molecular chains, which can significantly improve the strength and elasticity of PVC melt. This helps to avoid melt fracture and deformation during the processing, especially under high shear stress conditions. For example, enhanced melt strength during extrusion and injection molding processes can ensure the uniformity and stability of the product.

2. Improve impact resistance performance

High molecular weight ACR processing aids can improve the impact resistance of PVC products, making them less prone to breakage or damage when subjected to external impact. This is particularly important for applications that require high impact resistance, such as PVC pipes and profiles. Enhanced impact resistance can prolong the service life of products and improve their reliability.

3. Improve the rheological properties of the melt

High molecular weight ACR processing aids can adjust the rheological properties of PVC melt, allowing the melt to exhibit better fluidity and stability during the processing. This improvement helps to reduce flow marks and surface defects during the processing, producing products with a smooth and uniform surface.

4. Promote uniform dispersion

High molecular weight ACR processing aids can promote the uniform dispersion of fillers and other additives in the PVC matrix, preventing the aggregation or layering of fillers during the processing. Uniformly dispersed fillers help improve the mechanical and physical properties of products, such as enhancing their strength and durability.
