High molecular weight ACR (Acrylic Processing Aid) is a specialized additive designed to enhance the processing and performance of PVC foam boards. This additive is based on acrylic polymers with a high molecular weight, making it particularly effective in applications where superior mechanical properties and surface quality are essential.

Improved Melt Strength High molecular weight ACR significantly increases the melt strength of PVC during the extrusion process. This is crucial for PVC foam boards, as it ensures the stability of the foam structure, preventing collapse and achieving uniform cell distribution. The result is a consistent and high-quality foam board with excellent dimensional stability.

Enhanced Surface Finish The use of high molecular weight ACR in PVC foam boards leads to a smoother, more uniform surface finish. This improves the aesthetic appeal of the boards and enhances their suitability for applications requiring a high-quality surface, such as in signage, furniture, and construction materials.

Superior Mechanical Properties High molecular weight ACR enhances the mechanical properties of PVC foam boards, including impact resistance and tensile strength. This makes the boards more durable and resistant to damage, extending their service life in various applications.
