ABSTRACT

A preliminary study was made on the effect of castor oil on the properties of polyether based polyurethane foam such as rising time, density, hardness tensile strength, compression, elongation and heat aging. The castor oil was introduced into the polyurethane foam by partially substituting it for silicone oil through seven experimental set up, based on the laboratory mix formulation on 5OOg polyether based polyol with 0%, 20%, 40%, 50%, 60%, 80% and IOO% castor oil substitutions.
