  • Patent number: 10889680
    Abstract: A method of making flexible polyurethane foams mixes a polyol (a hydroxyl group containing compound) with a cesium and/or rubidium fluoride catalyst, and reacts such mixture with at least one isocyanate. The cesium and/or rubidium fluoride may be used as the sole catalyst, replacing the blowing and gelling catalysts, such as amines, and metallic catalysts, such as a tin catalyst. Or, the cesium and/or rubidium fluoride may be used as a catalyst promoter in combination with traditional amine blowing and gelling catalysts and tin catalysts. The resulting flexible polyurethane foams exhibit increased thermal conductivity and lower levels of volatile organic compound emissions.

  • Patent number: 10843508
    Abstract: A tire tread composition includes a quantity of an elastomer including guayule natural rubber, and a quantity of a hydrocarbon resin substantially evenly distributed throughout the elastomer. The elastomer of the tire tread composition may consist entirely of guayule natural rubber. The hydrocarbon resin may be selected to have a predetermined miscibility in the guayule natural rubber. The predetermined miscibility is measured by a deviation of actual Tg from predicted Tg for either the tire tread composition or an elastomer-resin mixture consistent with the elastomer and resin used in the tire tread composition. In particular, the predetermined miscibility in the guayule natural rubber is less than about six percent (6%) deviation in the actual Tg from the predicted Tg at a 20 phr loading.
