Abstract
A bio-based polyol-containing polymer foam material, which includes a bio-based polyol-containing polymer foam present in a bulk concentration of the bio-based polymer foam material of 99% by weight or greater; and a graphite material present in a bulk concentration of the bio-based polyol-containing polymer foam material of 1% by weight or less. The bio-based polyol-containing polymer foam material is especially suitable for automotive components having deadening and vibration management features.

A bio-based polyol-containing polymer foam material comprising:
- a bio-based polyol-containing polymer foam present in a bulk concentration of the bio-based polymer foam material of 99% by weight or greater;
- and
- a graphite nano-platelet (GNP) material present in a bulk concentration of the bio-based polyol-containing polymer foam material of 1% by weight or less and having a surface area of 120 to 150 m2/g.
A bio-based polyurethane foam comprising the reaction product of:
- a bio-based containing polyol;
- an isocyanate-containing compound;
- and
- a graphite nano-platelet (GNP) material present in a bulk concentration of 1% by weight or less and having a surface area of 120 to 150 m2/g,
- the bio-based polyurethane foam having a density in the range of 20-95 kg/m3, a wet compression set in the range of 5-50%, a tear resistance 200-350 N/m, and/or a tensile modulus in the range of 50-120 kPa.
A method for forming a bio-based polyurethane foam comprising the steps of:
- mixing a bio-based polyol with a petroleum-based polyol to obtain a bio-based polyol mixture;
- adding a graphite nano-platelet (GNP) material having a surface area of 120 to 150 m2/g to the bio-based polyol mixture to obtain a bio-based polyol-graphite mixture;
- and
- adding an isocyanate containing material to the bio-based polyol-graphite mixture to obtain a bio-based polyurethane foam mixture.
