Guayule-type resins are chemically treated with a reactive phenolic resin and a polyether such as an amine terminated polyether. The treated guayule resin has improved physical properties such as higher softening points. The resulting composition is suitable as a rubber additive since it improves various physical properties such as building tack, tear strength hysteresis loss, and the like.
Disclosed herein is a packaging system comprising predispersed chemicals in preweighed quantities embedded in multiple separated compartments of a masterbatch.
The present application relates to a thermally expandable composition containing an endothermic chemical blowing agent, to shaped bodies containing said composition and to a method for sealing and filling cavities in components, for strengthening or reinforcing components, in particular hollow components, and for bonding movable components using shaped bodies of this type.
