Systems and preparations for bio-based polyurethane foams

Abstract

The present invention consists of a series of bio-based polyurethane foams related to the use of such polyurethane foams for use in residential and commercial insulation industries, packaging industries and molding industries and in particular the invention includes systems and methods of manufacture and application of such bio-based polyurethane foams. The bio-based polyurethane foams are derived from castor oils, soybean oils and are not dependant on hydrocarbons, thus they are made from annually renewable natural resources.
