H 458P

Technical DataSheet | Supplied by Nanjing Hongbaoli

Blended polyol. It is a light yellow, transparent viscous liquid composed of fine cells and high closed cell content. Exhibits flame retardance, short demold time, good flowability, homogeneous density distribution, high compressive strength and good dimensional stability at both high & low temperature. Used in conjunction with MDI (methylene diphenyl diisocyanate) in HCFC-141b blowing systems and rigid polyurethane fomas. Recommended formulation is 100 pbw (parts by weight) for H 458P and 135-145 pbw for MDI.
