Bio-based polyurethane foam formulation and method thereof

Abstract

A bio-based polyurethane foam formulation, comprising a polyol component having 50-90% by weight of one or more bio-based polyols derived from renewable resources, an isocyanate component comprising 40-70% by weight of one or more isocyanates, one or more additives, optionally present, selected from nucleating agents, surfactants, pore-opening stabilizers, chain extenders, crosslinking agents, and bio-fillers, a catalyst system having a gelling catalyst and/or a blowing catalyst, a blowing agent system comprising a chemical blowing agent and/or a physical blowing agent. All weight percentages are based on the total formulation. The bio-based polyurethane foam has a predetermined thermal decomposition temperature, a predetermined tensile strength, and a predetermined elongation at break.
