Flooring product having regions of different recycle or renewable content
View Patent ↗A flooring product comprises a heterogeneous design layer having multiple regions wherein two regions comprise compositions having different recycle content or renewable content. The thickness of the design layer may be greater than the dimensions of the regions or the regions may extending from the top surface of the layer to the bottom surface of the design layer. The heterogeneous layer may be composed of consolidated particles/chips which may contain a polyester binder system with a renewable component. Additionally, a method for making a heterogeneous layer having a target wt % recycle content or renewable content is also disclosed.
1. A flooring product comprising a heterogeneous layer having at least a first region and a second region comprising consolidated chips or particles, the consolidated chips or particles comprising a polymer binder and a filler, the filler including renewable content portion or recycle content portion that imparts a color to the consolidated chips or particles, wherein a resulting first concentration of the renewable content or the recycle content of the consolidated chips or particles of the first region is different from a resulting second concentration of the renewable content or the recycle content of the consolidated chips or particles of the second region such that the color of the consolidated chips or particles of the first region is different from the second region, and
wherein the heterogeneous layer includes at least a first percentage by weight of the first region and a second percentage by weight of the second region, resulting in at least a first region renewable content or recycle content concentration and a second region renewable content or recycle content concentration such that the summation of at least the first region renewable content or recycle content concentration and the second region renewable content or recycle content concentration results in a total renewable content or recycle content of approximately 15 percent or greater by weight and the first percentage differs from the second percentage;
wherein at least one of the first region and the second region comprises a Biobased content of at least 5% by weight.
2. The flooring product of claim 1 , wherein the thickness of the heterogeneous layer is greater than the dimensions of the first region and the second region.

5. The flooring product of claim 1 , wherein the weight percent of the renewable content or the recycle content of the first region is different than the weight percent of the renewable content or the recycle content of the second region.
6. The flooring product of claim 1 , further comprising a third region having zero renewable content or recycle content.
7. The flooring product of claim 1 , wherein the first region is darker in color than the color of the second region and has a higher renewable content or recycle content than the renewable content or the recycle content of the second region.
8. The flooring product of claim 1 , wherein the polymer binder comprises a polyester resin, the polyester resin is a high molecular weight polyester resin, and the polyester resin comprises a renewable component.
9. The flooring product of claim 1 , wherein the first region and the second region extends from a top surface of the heterogeneous layer to a bottom surface of the heterogeneous layer.
10. The flooring product of claim 1 , wherein the recycle content portion of the filler includes fly ash.
11. The flooring product of claim 1 , wherein the high molecular weight polyester comprises at least one of polyethylene terephthalate, polybutylene terephthalate, and polypropylene terephthalate.
12. The flooring product of claim 1 , wherein the consolidated chips are throughout the flooring product.
13. The method of imparting the color to the consolidated chips of the flooring product of claim 1 .
14. The flooring product of claim 1 , wherein the filler of at least one of the first region and the second region further comprises a non-renewable or non-recycle filler.
15. The flooring product of claim 14 , wherein the non-renewable or non-recycle filler is titanium dioxide.
16. The flooring product of claim 1 , wherein the binder comprises a renewable component polyester portion and a recycle polyester resin portion, wherein the renewable component polyester portion is approximately 50 percent by weight and the recycle polyester resin portion is approximately 50 percent by weight, and wherein the renewable component polyester portion comprises a high molecular weight polyester with a molecular weight of greater than 5000.
17. The flooring product of claim 16 , wherein the recycle polyester resin portion comprises a recycle PET or PBT type resin.
18. The flooring product of claim 1 , wherein the polymer binder comprises an aliphatic acid.
19. The flooring product of claim 18 , wherein the aliphatic acid comprises at least one of sebacic acid, succinic acid, azelic acid, and citric acid.
