The transition to more sustainable materials is a must for the polyurethane industry. Oleon offers polyester polyols based on dimer acid technology to substitute petrochemical polyols without compromising the quality and performance. Our dimer acid polyester polyols provide specific enhanced properties to the final polyurethane, like water repellency and hydrolytic resistance, flexibility and elongation to make them the perfect building block for your C.A.S.E. (coating, adhesive, sealant, elastomer) and flexible foam applications.
