natural rubber
Noun: An elastic, polymeric material derived from the coagulated, milky sap (latex) of certain tropical plants, most notably the Hevea brasiliensis (rubber tree). This raw material can be processed, vulcanized (chemically treated with sulfur to increase strength and elasticity), and manufactured into a wide array of commercial products.
The term "natural rubber" is used to specify the raw, plant-based elastomer, distinguishing it from synthetic rubber made from petroleum. It is a mass noun, typically used without a plural form when referring to the substance itself. - The primary source of natural rubber is the rubber tree. - Tires were originally made from natural rubber. - Natural rubber has different elastic properties than its synthetic counterparts.
- The plantation specializes in harvesting latex for natural rubber.
- This surgical glove is made from high-quality natural rubber.
- Before the invention of vulcanization, natural rubber would become sticky in heat and brittle in cold.
- Technical/Industrial Context: In materials science and manufacturing, "natural rubber" refers specifically to , its primary chemical component, which gives it its unique elastic properties.
- Economic/Agricultural Context: The term is used in discussions about global commodities, supply chains, and the economies of producing countries.
- Rubber (noun): A broader term that can refer to both natural and synthetic elastomers, as well as erasers or specific items (e.g., a rubber tire). Context is needed to determine if it means natural rubber specifically.
- Latex (noun): The milky fluid tapped from the tree, which is the raw, uncoagulated form of natural rubber.
- Caoutchouc (noun): An older, technical term for raw, unvulcanized natural rubber.
- India rubber (noun): A historical term for natural rubber.
- Gum elastic (archaic)
- Para rubber (refers to rubber from the Brazilian region of Pará)
- Natural rubber latex: Emphasizes the liquid, pre-coagulated form, often relevant for allergy discussions.
- Natural rubber compound: Refers to natural rubber mixed with other ingredients (e.g., carbon black, antioxidants) for specific product manufacturing.
- Cultivated rubber: Specifies rubber from plantation trees, as opposed to wild sources.
- an elastic material obtained from the latex sap of trees (especially trees of the genera Hevea and Ficus) that can be vulcanized and finished into a variety of products
