CARPOL® GSP-370

CARPOL® GSP-370 is a glycerin/sucrose-initiated polyether polyol. The high functionality of the initiators yields a resultant polyol with a nominal functionality of seven and a typical hydroxyl number of 370. Due to this polyol’s high functionality, it is typically used in rigid foam and its applications. Blending this polyol with other polyether polyols allows for foam systems with high to lower degrees of crosslinking. In addition, CARPOL® GSP-370 is mildly catalytic, which enables the use of less catalyst while still providing the formulator with control over the system’s reactivity.
