The Bridgestone Group has been conducting integrated R&D activities from cultivation technology, natural rubber extraction process to application to tires toward practical use of guayule. Tire made from guayule-derived natural rubber In 2015, the Bridgestone Group produced the first tire made from guayule...
At factory level, the biorefiner needs to sell water-extracted rubber as latex. By adding solvent extraction, it is possible to extract the remaining percentage of total rubber and the resin. In such case, the biorefiner's profits rises to 鈧 691 ton1 of extracted rubber, making guayule ...

The quality of the rubber polymers in the latex fraction was investigated using size exclusion chromatography/multiangle laser light scattering detection. Polymer molecular weight and molecular radius declined in parallel, but both declined faster in the dilute homogenate generated from the second grind ...
some microbes are highly associated with other microbes in either competitive or cooperative microbe-microbe associations. Here, we aimed to determine whether there is overlap between critical microbes in plant-microbe and microbe-microbe associations by using guayule (a rubber-producing crop) as a mod...
This procedure would avoid the compacting of the shrub bed experienced with solvent percolation to recover rubber. This procedure is commonly called an immersion process. U.S. Pat. No. 2,390,860 relates to using for extraction a resin solvent as a resin solvent with a small amount of a ...

Extraction of latex rubber from Guayule has previously been described by Cornish in U.S. Pat. No. 5,590,942 (1996) and U.S. Pat. No. 5,717,050 (1998), both entitled Hypoallergenic Natural Rubber Products from Parthenium argentatum (Gray) and other non-Hevea brasiliensis Species. These ...
In the dried or conditioned state, the liquid rubber as laid down by the rubber-bearing cells has lost its characteristic Brownian movement and is considered to be coagulated. To be in "prime condition" as to moisture content for the extraction by the usual method of comminuting and/or mill...
