CARPOL® GSP-520 is a glycerin/sucrose-initiated polyether polyol. The high functionality of the initiators yields a resultant polyol with a nominal functionality of five and a typical hydroxyl number of 520. Due to this polyol’s high functionality, it is typically used in rigid foam and its applications. Blending CARPOL® GSP-520 with other polyether polyols allows for foam systems with high to lower degrees of crosslinking.
