Anionic surface sizing agent for linerboard

摘要

Recently, research, development and application specialists at BASF jointly completed work on a new product in the polymeric surface sizing agents (PSA) family that allows papermakers to significantly improve on sizing costs. Traditionally, PSA for the liner segment used cationic polymers. This however limited the coloration to certain product ranges. With Basoplast~? 450 P, BASF introduces a new and cost-efficient PSA for the packaging segment. The product is suited for linerboard grades.
