Hydrophilic Polyester Polyol LDMPA J5804 Widely used in various applications synthetic leather water-based polyurethane water-based resins
LDMPA is a hydroxyl-containing polycaprolactone obtained through the ring-opening of DMPA to form E-caprolactone. It retains the excellent properties of both hydroxyl and neopentyl structures while featuring a low melting point and excellent compatibility with polyester diols. As a polyester-type diol, LDMPA offers superior weather resistance and heat resistance compared to polyether polyols, along with enhanced hydrolysis resistance over adipic acid esters. It improves strength and abrasion res
