Rubber Wood - Tech & Spec Detas

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 cut the rubber trees and plant new ones.

This eco-friendly Rubber wood (Hevea Brasiliensis) is an excellent timber to use and its various attributes are outlined here.

APPEARANCE:

Color:

Pale cream to yellowish brown. Oxidative discoloration can be limited by rapid production sequence and vacuum drying.

Grain pattern:

Mostly straight. A cross section of Rubber wood 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 Rubber wood are similar to Ramin wood.

Structure:

Uniform in structure with an excellent Timber feel.
