PVC Acrylic Processing Aids HR Series

Product Description

HR-23 is a general purpose processing aid based on medium-high molecular weight. It is an acrylic copolymer that improves the processability and the performances of rigid PVC formulations . LP-21,B-23 is also extremely cost-effective, requiring only very low addition levels for high-quality results.
1) Promotes faster fusion, increases melt strength, enhances extensibility and improves melt homogeneity of the compounds.
2) Increases the surface quality of PVC products. Offers excellent wall-thickness control and good thermoforming capabilities
