Formatted abstract
A model rigid polyurethane foam has been enhanced in compressive strength and thermal conductivity by substituting up to 30 % of the polyether polyol with palm kernel oil polyester polyol. The optimal compressive strength at 20 % substitution was attributed to the formation of nanoscale hard segment domains in the cell walls/struts which compensates for the loss in compressive strength associated with the overall lower crosslink density. Attempts to use this phenomena to reduce the density (and thus cost) of the 20 % substituted foam, while maintaining compressive strength similar to the formulation based solely on polyether polyol, have been unsuccessful. The secondary structure disappeared in the low density foam. It was conjectured that at this lower density formulation provides insufficient secondary hard phase structure in the cell walls/struts to allow the hard segments to segregate into discrete rigid domains.
