Processing Aids

Processing aids are standard to high molecular weight acrylic copolymers which are very compatible with PVC. Added to the PVC compound in small quantities, they efficiently improve the PVC gelation from a slow, inhomogeneous melting process to a fast, homogeneous one. Furthermore, its addition remarkably enhances the melt strength and extensibility of PVC compounds required in production processes such as blow molding, film blowing, and thermoforming. Next to the improved processing, they upgrade the PVC surface quality from matt to the desired gloss level.
