Brief analysis: Alcohol chain extenders and cross-linking agents_Kain Industrial Additives

The influence of chain extenders and cross-linking agents For chemical cross-linking of polyurethane foam, the main way to achieve it is covalent bonding. Reactive isocyanates can react with many functional groups. Generally speaking, small molecule substances with two such functional groups are called chain extenders, while small molecule substances with more than two such functional…
