Presentation at UTECH Conference Maastrich, the Netherlands, April 17-19, 2012
At the international UTECH Exhibition and Conference in Maastrich, Holland, in April 2012, Green Urethanes confirmed the success of its latest work in increasing the viability of producing flexible foam containing natural oil polyols (NOPs), whilst safeguarding or improving the foams’ properties. High levels of renewable polyols (50 to 100 php) of all types can now be confidently used.
Green Urethanes also confirms development of a new series of High NOP Polymer Dispersions (HNPDs) for use in urethane foams. New research reveals in detail polymer dispersions based on GU prepolymers containing 50 php of a natural oil polyol. From this, a new classification of polymer dispersions has been established, based on high levels of NOP in combination with Polymer Polyol (PHD or PIPA) technologies.
Paper Abstract – Jeff Rowlands – Director
The desire to substitute the use of synthetic polyols, made from crude oil sources, with natural oil polyols, made from animal and vegetable sources, has always been frustrated by insurmountable processing or foam quality problems. This paper will present recent advances that enable up to 100% of the synthetic polyol in urethane formulations to be replaced by natural oil polyols of various kinds. New work also describes the development of novel, stable and foam-creating polymer dispersions based on a polyol containing at least 50% of a natural oil polyol.
