Abstract

Polyurethane (PU) formulated from natural polyols obtained from Tung oil (TO) have improved hydroxylation of the double bonds in the fatty acid chains of the unsaturated oil followed by the alcoholysis of the hydroxylated oil. The comparative chemical analysis between unmodified and modified TO suggested that the hydroxyl content increased significantly after the hydroxylation and alcoholysis reactions. Incorporated wood flour (WF), microcrystalline cellulose (MCC) or rice husk ash (RHA) as fillers in modified TO imparts between formulation in physical, thermal and mechanical properties of reinforced rigid PUs.
