Rubberwood--The Eco-friendly Timber

  

TreesWhat is Rubberwood?

Rubber plantations have existed for hundreds of years in tropical countries. These plantations have been used mainly for the production of latex. After the economic life of the rubber tree, which is generally 30 years, the latex yields become extremely low and the planters then fell the rubber trees and plant new ones. This eco-friendly Rubberwood (Hevea brasiliensis) is an excellent timber to use and its various attributes are outlined here:

  

APPEARANCE
A piece of Plywood Colour Pale cream to yellowish brown. Oxidative discolouration can be limited by rapid production sequence and vacuum drying
Grain pattern Mostly straight. A cross section of Rubberwood shows few concentric markings reminiscent of growth rings. These markings combined with the large vessels in structure give an attractive appearance with clear patterns on the longitudinal surface. Many characteristics of Rubberwood are similar to Ramin wood.
Structure Uniform in structure with an excellent 'Timber' feel.
