Identification of natural rubber samples for high-voltage
The natural latex from which the samples analyzed in this work were prepared, is a colloidal suspension, which was doubly centrifuged to rise the concentration of rubber particles. It was bought from diverse suppliers, mainly from Malaysia and Brazil, and was applied as received.

Identification of Natural Rubber and Characterization
Natural rubber is a polymer composed of 320 to 35,000 isoprene molecules. Among the natural rubber producing plant species, the Brazilian rubber tree (Hevea brasiliensis) is the only commercial source at present, due to its high rubber content and quality (Backhaus, 1985). However, diminishing acreage of rubber plantations and life-threatening allergies to the latex based products of rubber tree, coupled with increasing demand for high quality rubber, point to a need for alternative natural ...

Natural rubber
Hevea brasiliensis. The major commercial source of natural rubber latex is the Pará rubber tree ( Hevea brasiliensis ), a member of the spurge family, Euphorbiaceae. This species is preferred because it grows well under cultivation. A properly managed tree responds to wounding by producing more latex for several years.

Natural Rubber as Electrical Insulator: A Review
Natural Rubber as Electrical Insulator: A Review. It is almost the only commercial rubber from a natural source. Natural rubber-based insulations for electrical wire dates from the earliest days of the electrical industry. It was the only polymeric material used as a wire and cable dielectric up to the 1930s, when the first suitable synthetics became...
