Historical results include the Resin and Specialty Coatings businesses within the Performance Products and Solutions segment.

CORE™ Vinyl Powder Coatings are dry blends of suspension PVC resins that are plasticized for flexibility

Avient’s portfolio of healthcare colorants includes standard and customized color solutions for a variety of polymers, from polyolefins, PC, PEBA, ABS, and styrenics to high temperature polysulfone resins.

Based in polysulfone resins, these sophisticated options are well-suited for demanding and reusable applications subject to multiple sterilization cycles and harsh cleaning agents.

Monomers make up the majority of the variable cost of manufacturing the base resin. The distribution of polymer resin is also highly competitive. Most of the chlorine manufactured by SunBelt is used to produce PVC resin.
