New application of guayule resin in controlled release formulations

Industrial Crops and Products, 2013
Abstract Guayule resin is a by-product of the rubber extraction process from Parthenium argentatum Gray shrubs. When guayule is cultivated to a large extent, it is possible to achieve a production of 200–2000 kg/ha of resin in addition to the commercial natural rubber production that is sought for use as hypoallergenic latex.

Biomass, rubber, and resin yield potentials of new guayule germplasm

Bioresource Technology, 1991
Abstract Substantial improvement in rubber yield must be made in order to establish guayule as a reliable source of natural rubber. Selection among heterogeneous apomictic polyploids was used to improve rubber yield in a relatively short period of time.

Effect of Resin Components on the Reversion Process of Sulfur-Vulcanized Guayule Rubber

Rubber Chemistry and Technology, 1986
Abstract An effort to characterize the reversion process of guayule rubber when naturally-occurring guayule resin components are present has shown that these components act as a reversion-retarding material. The amount of reversion resistance varies as a function of temperature, concentration, and type of fatty acid.

Extraction of natural rubber and resin from guayule using an accelerated solvent extractor

Industrial Crops and Products, 2013
Abstract Accelerated solvent extraction is a relatively rapid automated method for extracting compounds of interest from plant materials. We have developed a sequential solvent extraction method that can be used to accurately quantify the rubber and resin in samples of guayule ( Parthenium argentatum Gray), a new industrial crop now in commercial ...

Conversion of guayule resin to C1-C10 hydrocarbons on zeolite based catalysts

Fuel, 1992
Abstract The conversion of guayule resin to C 1 -C 10 hydrocarbons, using different zeolite based catalysts, has been studied. HY, CaHX and HZSM-5 zeolites and a silica-alumina amorphous matrix were tested. The best results were obtained with a physical mixture of 70 wt% HZSM-5 zeolite ( Si Al = 13 ) and 30 wt% silica-alumina amorphous ...

Post-harvest storage effects on guayule latex, rubber, and resin contents and yields

Industrial Crops and Products, 2009
Guayule is a new crop being commercialized for hypoallergenic latex production. Because natural processes that occur in the plant following harvest, notably dehydration, result in rapid loss of latex and immediate processing of guayule shrub for latex on a commercial scale is not feasible, storage conditions that maintain latex concentration and yield ...

Intensification of the aqueous phase extraction process (without solvent) of guayule resin

L'un des défis du XXIe siècle est l'accès limité aux ressources, notamment aux matériaux, utilisés dans tous les domaines de la vie quotidienne. En 2020, le caoutchouc naturel (matériau obtenu par la transformation du latex) est intégré à la liste des ...
