Is Natural Rubber White?

Published in Rubber Properties 1 min read

Yes, natural rubber in its initial form is white.

Understanding Natural Rubber's Color

Natural rubber originates from the rubber tree (Hevea brasiliensis) as a milky liquid called latex. This latex is harvested by making incisions in the tree bark, a process known as tapping.

The Color of Latex

According to the provided reference, natural rubber exits the tree as a white, milky latex. The reference explicitly states, "Unless the latex is contaminated, that means the natural color of rubber straight from the tree is white."

  • Initial Form: White, milky liquid (latex)
  • Harvesting: Tapped from rubber trees
  • Natural State: White, assuming no contamination

This means that the raw material, the latex drawn directly from the tree, has a white appearance.

While processed rubber products can come in various colors due to added pigments, the natural state of the raw rubber material is white.
