As it is often impossible to preserve the latex sufficiently to get it to a factory that processes latex in time for it to be used to make high quality products, and as the latex would anyway have coagulated by the time it reached the factory, the smallholder will coagulate it by any means available, in any container available. 3. After 90 days, the packaged membranes showed satisfactory antioxidant activity. After mechanical forces stretch a rubber membrane (yellow), the compliant electrodes (gray) on opposing faces of the stretched membrane receive charges of opposite polarities from an external source. The restoring force is due to the preponderance of wrinkled conformations over more linear ones. The biomembrane is held tightly to the rubber core by the high negative charge along the double bonds of the rubber polymer backbone. Natural rubber is not cultivated widely in its native continent of South America because of the South American leaf blight, and other . [22][23] When latex concentrate is produced from rubber, sulfuric acid is used for coagulation. Smallholders' lump is produced by smallholders, who collect rubber from trees far from the nearest factory. For this reason, tapping cuts usually ascend to the left to cut more tubes.
