Hevea Brasiliensis Hardwood

Species Identity: Hevea Brasiliensis

Common Names: Rubberwood, Parawood

Compare to: Northern Red Oak

Hevea Brasiliensis is a hardwood from the Maple family of hardwoods & has very little tendancy to warp or crack, is eco-friendly & is often the most misunderstood species of wood in the furniture industry. The name Rubberwood invokes a variety of misconceptions as to it's features and to it's durability. Rubberwood (also called Parawood in Thailand) is the standard common name for the timber of Hevea Brasiliensis.

In fact, Hevea Brasiliensis is one of the more durable lumbers used in the manufacturing of today's home furnishings. As a member of the Maple family, Hevea Brasiliensis has a dense grain character that is easily controlled in the kiln drying process. Hevea Brasiliensis has very little shrinkage making it one of the more stable construction materials availabe for furniture manufacturing.

As a Maple hardwood, Hevea Brasiliensis is a sap producing species. In the case of Maple, it is sap; in the case of Hevea Brasiliensis, it is latex.

There is one more important feature of Hevea Brasiliensis that is very important in today's world. Hevea Brasiliensis is the most ecologically "friendly" lumber used in today's furniture industry. After the economic life of the Rubber tree, which is generally 26-30 years, the latex yields become extremely low and the planters then fell the Hevea Brasiliensis trees and plant new ones. So, unlike other woods that are cut down for the sole purpose of producing furniture, Hevea Brasiliensis is used only after it completes it's latex producing cycle and dies. This wood is therefore eco-friendly in the sense that we are now using what was going as waste.

Do not mistake the name Hevea Brasiliensis when it comes to its quality features.

General Information: The Hevea Brasiliensis tree reaches a height of over 30m, and is from the same family as Maple. They both produce sap. The sap from rubber trees is known as latex. Hevea Brasiliensis trees produce all the latex in the world for all rubber-based products.

The economic life of a Hevea Brasiliensis tree (i.e. number of years it produces latex) is roughly 25 to 30 yrs. After the trees die, they are felled and new ones are planted.

Historically, the felled timber was used as firewood to fuel brick-making and tobacco-curing. The commercial value of Hevea Brasiliensis was negligible till about 15yrs ago. Dramatic changes in world economy plus the occurence of natural disasters in some parts of the world necessitated the need for quality alternative hardwood timbers.
