摘要： Processes for recovering natural rubber from an aqueous natural rubber latex that contains extractables and one or more additives and that is essentially free of lignocellulosic plant material are described. Natural rubber in the latex is separated from the water. Preferably, the amount of non-rubber extractables in the natural rubber is reduced by one or more extraction steps yielding a dried natural rubber.

摘要： Provided herein are cured rubber compositions containing guayule natural rubber with 2.5-4 weight % resin and fillers. By the use of a specified cure package that contains increased amounts of sulfur and accelerator, the cured rubber compositions are found to exhibit strain induced crystallization (as can be observed by X-ray diffraction). Also provided are related methods for preparing the rubber compositions.
