Webformulation involves three major components: (1) poly/diisocyanates, (2) polyols, and (3) chain extenders [1]. Chain extenders are usually aliphatic or aromatic diols and diamines employed to build up the polymer molecular weight and increase the block length of hard segments by reacting with the isocyanate compounds [2].
