In the manufacture of rigid polyurethane foam having a low road surface abrasion useful, there is provided a polyol formulation comprising a specific type of polyester polyol. In one embodiment, the reaction system is provided for the production of rigid foams. The reaction system includes a polyester polyol and at least one polyisocyanate and a polyester polyol and a polyisocyanate are mixed in an amount sufficient to provide a rigid polyurethane foam. Polyester polyol is an aromatic component comprising at least 80 mole% of terephthalic acid 20 to 60% by weight, 150 to 1,000 can be a polyethylene glycol having an average molecular weight of from 20 to 60% by weight, a glycol having a molecular weight of bifunctional and 60 to 250 5 to 20% by weight and comprises three or more functional and of 60 to 250 glycol 5 to 20% by weight of the reaction product has a molecular weight of.
