Origin of Natural Rubber Latex

Rubber trees – unique beauty containing industrial necessity.

Asia produces nearly 72 percent of the world’s natural rubber latex, with Thailand, Indonesia and Malaysia as its major exporters.

Though it’s sometimes mistaken as the sap of the Hevea tree, latex actuality runs through ducts in a layer just outside the cambium below the tree’s bark.

With a sharp knife, a tree tapper shaves off the thinnest layer from a section of the bark. This gets the latex flowing, and the tapper will leave a small cup underneath the cut to collect the latex. At the end of the day, the tapper will empty the cups into containers and deliver it to a processing station.

There, the latex is strained and concentrated. It then goes into a centrifuge to remove some of the water and increase the rubber content. After the centrifuging process, the material is known as latex concentrate and contains roughly 60 percent solid rubber.

We use this latex concentrate in our dipping process.
