Production and characterization of polyurethane castor oil (Ricinus communis) foam for nautical fender
(2019-02-01)
Due to the fact that in South America old tires have been usually tied to vessels and convoys for the purpose of their lateral protection, this study was designed to address a contribution to the replacement of such material, ...
Polyurethane foams obtained from castor oil-based polyol and filled with wood flour
(Sage Publications Ltd, 2009-12)
A natural polyol was prepared from castor oil by alcoholysis with triethanolamine. The oil and the oil-based polyol were characterized by infrared spectroscopy and through the analytical determination of their functional ...
Efficiency of castor oil–based polyurethane foams for oil sorption S10 and S500: Influence of porous size and statistical analysis
(2021-01-01)
This study evaluates the efficiency of castor oil–based polyurethane foams for oil sorption S10 and S500, focusing on the influence of the pores’ size. Different foams were produced by varying the polyol: isocyanate ratio ...
