2. Natural rubber - Wikipedia

   en.wikipedia.org/wiki/Natural_rubber

   Torn latex rubber dry suit wrist seal. Natural rubber is reactive and vulnerable to oxidization, but it can be stabilized through a heating process called vulcanization. Vulcanization is a process by which the rubber is heated and sulfur, peroxide, or bisphenol are added to improve resistance and elasticity and to prevent it from oxidizing.

3. Latex allergy - Wikipedia

   en.wikipedia.org/wiki/Latex_allergy

   Latex allergy is a medical term encompassing a range of allergic reactions to the proteins present in natural rubber latex. [1] It generally develops after repeated exposure to products containing natural rubber latex. When latex-containing medical devices or supplies come in contact with mucous membranes, the membranes may absorb latex proteins.

4. Vytex Natural Rubber Latex - Wikipedia

   en.wikipedia.org/wiki/Vytex_Natural_Rubber_Latex

   Vytex Natural Rubber Latex comes from the Hevea brasiliensis rubber tree, which is primarily cultivated in Southeast Asia. Natural rubber latex is a cloudy white liquid collected by cutting a thin strip of bark from the tree and allowing the latex to be secreted into a collection cup over a period of several hours.

5. Rubber tapping - Wikipedia

   en.wikipedia.org/wiki/Rubber_tapping

   Rubber tapping is the process by which latex is collected from a rubber tree. The latex is harvested by slicing a groove into the bark of the tree at a depth of one-quarter inch (6.4 mm) with a hooked knife and peeling back the bark. Trees must be approximately six years old and six inches (150 mm) in diameter in order to be tapped for latex.

6. Crepe rubber - Wikipedia

   en.wikipedia.org/wiki/Crepe_rubber

   Pale latex crepe (PLC) is a premium grade, made from raw field latex. Estate brown crepe (EBC) is made from "cup lump" (raw, naturally coagulated rubber from the collection cup) and other coagula. Re-milled crepe is made from "wet slab coagulum" (cured latex, still wet from the coagulation tanks), latex sheets (unsmoked) and cup lump.

7. Rubber elasticity - Wikipedia

   en.wikipedia.org/wiki/Rubber_elasticity

   A rubber band is a single molecule, as is a latex glove. The sections of polyisoprene between two adjacent cross-links are called network chains and can contain up to several hundred isoprene units. In natural rubber, each cross-link produces a network node with four chains emanating from it.
