Natural rubber
Natural rubber is a stretchy, waterproof polymer from tree latex.
Natural rubber, also called India rubber, latex, Amazonian rubber, caucho, or caoutchouc, consists of polymers of the organic compound isoprene with minor impurities. It is harvested mainly as latex from the Pará rubber tree (Hevea brasiliensis) or other plants, and is classified as an elastomer. Natural rubber is used extensively in many applications and products, either alone or in combination with other materials, and is noted for its large stretch ratio, high resilience, buoyancy, and waterproofness.

Lore & Background
The first use of rubber was by the indigenous cultures of Mesoamerica, with the earliest archeological evidence from the Olmec culture, who used it for balls in the Mesoamerican ballgame. The Maya and Aztec also used rubber for balls, containers, and waterproofing textiles.
Reader's Guide
Natural rubber has been a critical material for millennia, from its origins in Mesoamerican ballgames to its modern role in tires, gloves, and countless industrial products. The demand for rubber drove colonial exploitation, notably the atrocities in the Congo Free State under King Leopold II and the Putumayo genocide in South America, where forced labor and violence were used to collect latex. Today, Thailand, Malaysia, Indonesia, and Cambodia are leading producers, and research continues on alternative sources such as the Kazakh dandelion.
Did You Know?
- The earliest archeological evidence of natural rubber use comes from the Olmec culture, who made balls for the Mesoamerican ballgame.
- In Nazi Germany, research projects tried to use dandelions as a base for rubber production but failed.
Frequently Asked Questions
Who is Natural rubber?
Natural rubber (also called India rubber, latex, caucho, or caoutchouc) is an elastomeric polymer built from isoprene chains, harvested primarily as latex sap from the Pará rubber tree (Hevea brasiliensis). It is the stretchy, waterproof material behind everything from tires to rubber bands.
What are Natural rubber's key abilities?
Its standout traits include an exceptionally high stretch ratio, strong resilience after deformation, natural buoyancy, and waterproofness. These properties make it ideal for industrial seals, consumer goods, and countless other applications, either on its own or blended with other materials.
Why is Natural rubber important to the materials canon?
It was one of the first widely used elastomers in human history, bridging ancient Mesoamerican craftsmanship to modern industrial manufacturing. Its unique blend of stretch, resilience, and waterproofing still gives it applications that many synthetic alternatives struggle to fully replicate.
