タイトルまたは説明

Hydroxyapatite, as an inorganic dispersant, is mainly used in suspension polymerization of polystyrene (PS), expandable polystyrene (EPS) and SAN beads in ABS. The polymerization temperature and pressure change smoothly, and the materials are not easy to touch the kettle, which can prolong the kettle cleaning cycle and improve the appearance quality and transparency of the product. At the same time, the particle size distribution of polymerization products is also relatively concentrated, especially in the manufacture of coarse resin products, which has greater advantages over organic dispersants such as hydroxyethyl cellulose (HEC), polyvinyl alcohol (PVA), gelatin, and sodium carboxymethyl cellulose.
