    Abstract: A method of producing a polyurethane based foam that includes providing a ground crop residue having an average particle size of less than 10 mm and that is prepared by grinding crop residues, providing a polyurethane system that includes an isocyanate component and an isocyanate-reactive component, of which the polyurethane system has an isocyanate index from 70 to 350, forming a modified polyurethane system by adding the ground crop residue to the polyurethane system in a range from 1.0 wt % to 20.0 wt %, based on a total weight of the modified polyurethane system, and forming the polyurethane based foam so as to have an applied density from 30 kg/m3 to 75 kg/m3, according to ASTM D-1622, and to have the ground crop residue embedded within polyurethane polymers that are a reaction product of the isocyanate component and the isocyanate-reactive component of the polyurethane system.

    Abstract: Embodiments of the present disclosure provide for a composition for forming a polyurethane foam and a method of forming the polyurethane foam using the composition. The polyurethane foam includes a formulated polyol, an isocyanate and a blowing agent. The formulated polyol includes 60 weight percent (wt. %) to 80 wt. % of a polyether polyol and 10 wt. % to 25 wt. % of an aromatic polyester polyol, where the wt. % are based on a total weight of the formulated polyol, and where the formulated polyol has a polyol mixture functionality of 3.8 to 5.5.

    Abstract translation: 本公开的实施方案提供了用于形成聚氨酯泡沫的组合物和使用该组合物形成聚氨酯泡沫的方法。 聚氨酯泡沫包括配制的多元醇，异氰酸酯和发泡剂。 配制的多元醇包括60重量％（wt。％）至80wt。 ％的聚醚多元醇和10wt。 ％至25wt。 ％的芳族聚酯多元醇，其中wt。 ％是基于所配制的多元醇的总重量，并且其中配制的多元醇具有3.8至5.5的多元醇混合物官能度。
