Abstract
Provided herein are conglomerate resin compositions, methods for the creation of conglomerate resins made from waste stream materials, and incorporation of conglomerate resins in the construction of sporting goods equipment, including, for example, alpine skis, touring skis, cross country skis, approach skis, split boards, snowboards, and water skis.
Claims22
A conglomerate resin, comprising:
- a) a waste stream material, wherein the waste stream material comprises a polyurethane, wherein the polyurethane is formulated with a biobased polyol derived from a microbial oil, wherein the waste stream material is from about 50% to about 90% weight-by-weight (w/w) of the conglomerate resin;
- b) an epoxy resin, wherein the epoxy resin is from about 1% to about 25% w/w of the conglomerate resin;
- and
- c) a hardener, wherein the hardener is from about 1% to about 25% w/w of the conglomerate resin.
1 more element
A conglomerate resin, comprising:
- a) a waste stream material, wherein the waste stream material comprises a polyurethane, wherein the polyurethane is formulated with a biobased polyol, wherein the biobased polyol has a C18:1 content of at least 60%, wherein the waste stream material is from about 50% to about 90% weight-by-weight (w/w) of the conglomerate resin;
- b) an epoxy resin, wherein the epoxy resin is from about 1% to about 25% w/w of the conglomerate resin;
- and
- c) a hardener, wherein the hardener is from about 1% to about 25% w/w of the conglomerate resin.
