  • Publication number: 20250066530
    Abstract: There is described a foamed isocyanate-based polymer derived from a reaction mixture comprising: an isocyanate; a polyol composition comprising a first prescribed amount of polymer particles dispersed in a base polyol; a second prescribed amount of biomass-based carbonaceous particulate material; and a blowing agent. In one embodiement, the foamed isocyanate-based polymer having an Indentation Force Deflection when measured pursuant to ASTM D3574-11 which is within about 15% as that of a reference foam produced by omitting the biomass-based carbonaceous particulate material from the reaction mixture and increasing the amount of polymer particles in the polymer polyol composition to equal the sum of the first prescribed amount and the second prescribed amount.
