%X the production of rigid polyurethane foams is made varying the soy-based polyol percentage between 20 and 30% into the formulation. four blocks of foam are obtained using two oleochemicals polyols from ethanol and ethylenglycol (with funcionalities of 2 and 6, respectively). the foams were characterized by thermal and mechanic tests finding a conductivity value between 0.022-0.026 w/mk and a compressive strength of 15-20 psi, comparables with the commercial specifications and showing the obtained product as appropriate pu foam for industrial applications.
