PETOL 250-3 is a polyoxypropylene triol, 670-average molecular weight. This polyether triol is used in the manufacture of rigid, semi-rigid and special flexible polyurethane foams. If blended with other PETOL polyols, it can vary physical and mechanical characteristics of semi-rigid and rigid polyurethane foams. The product is also used in blends for applications used in the production of coatings, adhesives and casting elastomers.
