Abstract
Official abstract text for this publication.
A foam material includes the reaction product of a polyol mixture and an isocyanate mixture and a boron nitride filer in an amount of ≥ 0.01 wt. % to ≤ 0.1 wt. %. In various forms, the boron nitride filer is of nanoparticles, is of hexagonal boron nitride, and/or is treated with a silane coupling agent.
First claim
Opening claim text (preview).
1 . A foam material comprising the reaction product of a polyol mixture and an isocyanate mixture, and a boron nitride filler in an amount from 0.01 wt. % to less than 0.1 wt. %, the polyol mixture being bio-based, wherein a wet compression set of the foam material is less than about 13%. 2 . The foam material according to claim 1 , wherein the boron nitride filler is hexagonal boron nitride. 3 . The foam material according to claim 1 , wherein the boron nitride filler consists of nanoparticles. 4 . The foam material according to claim 1 , wherein the boron nitride filler is treated with a silane coupling agent. 5 . (canceled) 6 . The foam material according to claim 1 , wherein the reaction product is a polyurethane material. 7 . (canceled) 8 . The foam material according to claim 7 , wherein the bio-based polyol mixture comprises 50 wt. % petroleum-based polyol and 50 wt. % bio-based polyol. 9 . The foam material according to claim 6 , wherein the bio-based polyol mixture is 100 wt. % bio-based. 10 . The foam material according to claim 1 , wherein the foam material is flexible. 11 . A part comprising the foam material according to claim 1 . 12 . A foam material comprising the reaction product of a polyol mixture and an isocyanate mixture, and a boron nitride filler in an amount from 0.01 wt. % to about 0.1 wt. %, the boron nitride filler being in the form of nanoparticles, the polyol mixture being bio-based, wherein a wet compression set of the foam material is less than about 13%. 13 . The foam material according to claim 12 , wherein the boron nitride is treated with a silane coupling agent. 14 . The foam material according to claim 12 , wherein the reaction product is a polyurethane material. 15 . (canceled) 16 . The foam material according to claim 15 , wherein the bio-based polyol—is 100 wt. % bio-based. 17 . A foam material comprising: the reaction product of a polyol mixture and an isocyanate mixture; and a boron nitride filler in an amount from 0.01 wt. % to about 0.1 wt. %, the boron nitride filler being in the form of nanoparticles and treated with a silane coupling agent, the polyol mixture being bio-based, wherein a wet compression set of the foam material is less than about 13%. 18 - 19 . (canceled) 20 . The foam material according to claim 17 , wherein the reaction product is a polyurethane material.
