CARPOL® GSP-520

1 of 41 products in this brand
CARPOL® GSP-520 is a glycerine/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 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 lower degrees of crosslinking.
