Hevea - the wood from the rubber tree


Rubber trees are not just ornamental trees for our living rooms. Some types of rubber trees (which are not related to the native rubber tree) also provide an interesting and durable wood, which is used more and more often. Find out more about Hevea wood in this post.

other names

The wood of latex trees) is also called "rubberwood". The term "rubber tree wood" is misleading insofar as the rubber tree from the domestic living room with the latex trees is not directly related botanically. Scientifically, the latex trees are called Hevea, while the rubber tree is called Ficus elastica.

DIN designation

The DIN designation for the wood of the rubber trees is HVBR.

Appearance

Grain

Hevea is medium to coarse-pored, the pores are irregularly scattered, but mostly arranged in groups. Very often you can see just running pore grooves.

colour

Hevea only consists of sapwood - there is no heartwood in this species. Accordingly, the color of the whole wood is the same color as the sapwood - yellowish white. Over time, however, the wood may turn yellow, and then assume a yellowish-brown hue, which has a distinct yellowing effect.

properties

The properties of Hevea wood are very similar to those of Ramin wood, only the weight of Hevea wood is about one tenth higher. The workability is usually quite good, but tools can resinify again and again when editing. Hevea wood is relatively hard: its hardness is well above that of oak wood. While oak wood only has a Brinell hardness of 4.3 (Beech about 4.1), Hevea has a value of around 6.2.

Shrinkage and drying

Hevea can only be used very well dried, the wood moisture should be below 10% in any case. The drying is fast, the shrinkage is moderate.

resistance

Hevea wood is hardly resistant to fungus and insects, and not weatherproof. A use can therefore only be made indoors. According to the DIN Hevea wood is classified in the resistance class 5 ("not permanent).

use

Hevea can be used in furniture as well as parquet as solid wood, as it is visually very appealing. In many countries of South America it is already the most common furniture wood, with us the use increases only slowly. Occasionally it is also used for the production of doors and for musical instrument making.

ancestry

Of course, Hevea is native to many South American areas. However, the wood used today often comes from South Asian areas where the Hevea trees are planted for plantation-based rubber production (so-called "rubber belt"). If they no longer deliver rubber, they are felled and used for timber extraction.

Tips & Tricks

Due to the increase in rubber production and the increased reuse of the rubber trees, Hevea will probably gain more and more importance in the future as wood for interior construction.
