CARPOL® GSP-280

CARPOL® GSP-280 is a glycerin/sucrose-initiated polyether polyol. The high functionality of the initiators yields a resultant polyol with a functionality of seven and a typical hydroxyl value of 280. Due to this polyol’s functionality, its niche is 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-280 is mildly catalytic, which enables the use of less catalyst while still providing the formulator with control over the system’s reactivity.
