CARPOL® GSP-355

CARPOL® GSP-355 is a glycerin/sucrose-initiated polyether polyol. The high functionality of the initiators yields a resultant polyol with a nominal functionality of 4.5 and a typical hydroxyl number of 355. Due to this polyol’s high functional nature, it is typically used in rigid foam and its applications. Blending this polyol with other polyether polyols allows for foam systems with high to low degrees of crosslinking. In addition, CARPOL® GSP-355 is a neutral material, which presents the formulator with complete catalytic control over a system.
