URL: https://www.tsrchem.com/something-you-need-to-know-about-1-4-butanediol.html With its reactive primary hydroxyl functionality and linear structure, 1,4-butanediol (BDO) is a flexible liquid diol intermediate that makes it easy to create polyurethane elastomers with the best possible balance of characteristics and price. BDO is a preferred chain extender for Polyurethane Elastomers. Most processors use 1,4-BDO as their preferred chain extender for MDI or H12MDI systems. When acting in this capacity, BDO effectively produces crystalline "hard segment" domains that effectively microphase separate when it combines with MDI, H12MDI, and other aliphatic isocyanates or prepolymers. Numerous investigations have demonstrated that the degree and accuracy of this hard-block phase separation strongly influence the characteristics of polyurethane. BDO, a urethane chain extender, produces polyurethane elastomers that are hard, strong, long-lasting, and thermally sta...
