PVC Foam Regulator
Acrylic foam regulators are a special class of high molecular weight processing aids, specifically designed for foamed PVC formulations. These additives enhance melt strength, control gas distribution, and stabilize bubbles, ultimately leading to the formation of a fine and uniform cell structure. This coherent morphology not only improves surface quality but also ensures weight reduction and achieves low product density.
The key role of foam regulators in preventing cell collapse or rupture during processing has made them an essential component in the production of foamed sheets, lightweight profiles, and extruded parts widely used in construction and decorative industries. Compared to conventional processing aids, which primarily influence fusion and melt flow, foam regulators provide significantly higher melt strength, making them an indispensable choice for manufacturing foamed PVC products.
