Silicone rubber and natural rubber as biomaterials
Medical & Biological Engineering & Computing, 1980The roles of silicone rubber and natural rubber as biomaterials are contrasted, with silicone rubber being widely used and natural rubber having, as yet, found limited application. Relevant properties of both elastomers are described, applications are discussed and possible future developments are considered.

Natural rubber blends with epoxidized natural rubber
Journal of Macromolecular Science, Part B, 1997Abstract Blends of NR with ENR have been prepared in full composition following the polymer blend technique. Basic properties (mastication behavior and thermal degradation of each rubber and Mooney viscosity, Flory-Huggins interaction parameters, and cure characteristics of the blends) of the uncured blends were determined, in addition to the reversion,

Natural rubber, India rubber and caoutchouc are all names for the solid elastic material isolated, one way or another, from the ‘milk’ or latex of Hevea brasiliensis, and various other tropical plants like Castilloa elastica. Natural rubber and natural rubber products have been known to the ancient cultures of Amazonia and Mesoamerica since time ...

Infrared studies on natural rubber and aged natural rubber
Journal of Polymer Science, 1955AbstractIn the infrared absorption spectra of solutions of natural rubber in carbon tetrachloride, two new absorptions are observed, one at 6.52 μ and another at 8.2 μ. These bands disappear when films from the solution are examined. Possible origins of these bands are discussed and it is suggested that the absorption at 6.52 μ may be due to a ...

Biodegradation of natural rubber and deproteinized natural rubber by enrichment bacterial consortia
Biodegradation, 2020This study examined the biodegradation of natural rubber (NR) and deproteinized natural rubber (DPNR) by bacterial consortia enriched from a rubber-processing factory's waste in Vietnam. The results reveal the degradation in both NR and DPNR, and the DPNR was degraded easier than NR.

NATURAL AND SYNTHETIC RUBBER. I. PRODUCTS OF THE DESTRUCTIVE DISTILLATION OF NATURAL RUBBER
Journal of the American Chemical Society, 1929Abstract Two hundred pounds of pale crepe rubber have been destructively-distilled at atmospheric pressure. The distillate was fractionated and its components identified from C5 to C10, as shown in the table. Assuming that the Staudinger formula is correct, that the single bonds furthest from the double bonds are the weaker spots and that the ...
