PLURACOL 220
PLURACOL 220
PLURACOL® 220 polyol (Specialty Polyol) is a high molecular weight, primary hydroxyl terminated polyol used in polyurethane elastomer and sealant formulations.
PLURACOL® is a diverse range of polyether polyols including conventional and graft polyols. The PLURACOL graft series are polyether products containing dispersed particles of co-polymerized styrene and acrylonitrile, or SAN particles. These products offer property improvements for certain applications such as flexible foam and urethane elastomers.
