Product Advantages
It is a linear aliphatic polyester diol polymerized from 1,4-butylene glycol and adipic acid. It features regular molecular chains and good crystallinity, with stable terminal hydroxyl groups and moderate reactivity with isocyanates such as MDI. PU materials made from PBA deliver superior tensile strength, tear strength, outstanding abrasion resistance and excellent mineral oil resistance, along with great resilience.
