What is Rubberwood
Rubber wood is the product of the rubber tree (Hevea brasiliensis), which is grown as a source for natural rubber. Also goes by the name parawood. It’s Mainly grown in Asia. If you look for furniture or other wooden items at large retail outlets, chances are good that you have seen rubber wood.
Wild rubber wood trees can grow to over 100′ but cultivated trees are shorter, with tapered trunks about 20 inches in diameter. The wood is a light-colored, diffuse-porous hardwood with narrow rays. Large vessels (pores) result in a somewhat coarse grain. Rubber wood is not rubbery; in fact it is moderately hard and stiff. It dries and machines rather easily and shrinkage is moderate. Rubber wood has low natural durability and must be treated with preservatives for outdoor use. Small pieces of rubber wood are often finger-jointed and edge-glued to make panels, which are then used for table tops, trays, chair seats, etc. Rubber wood is also called parawood, white teak or Malaysian oak, although its appearance and properties are different than teak or oak.
When the economic life of the rubber tree, usually after 30 years, the latex production become very low, the planters then cut the rubber trees and grow new ones. This eco-friendly wood (Hevea brasiliensis) is an excellent timber to use. The colour of the same is Pale cream to yellowish brown, its uniform in structure with an excellent timber feel.
With trees being chopped and quality of wood being compromised, the easy availability of rubber trees has led to the finding of an alternative to the conventional sources of wood. Currently, people rely on rubber wood as it has the qualities that enable them to cut it easily, sew as per the woodworks and turn screws wherever required. It can withstand robust conditions and provides extreme quality even after several years of usage.
It is a moderately hard and ‘light to moderately heavy’ timber with density ranging from 435 to 626 kg/m3 at 12% moisture content. It is a diffuse porous wood with medium texture and straight grain. Sapwood and heartwood are not distinct. Occurrence of tension in wood is seen as white lustrous zones, when freshly cut is a characteristic feature of rubber wood.
- Rubber wood can be exported to gain large revenue as its market value keeps on increasing. It is seen an alternative source of fuel as well.
- The strength offered by this wood is far better than the ones offered by the traditional wood, which we have known for several years. The finishing that rubber wood offers is smooth and provides the same quality that is offered by teak.
- Rubber wood is easy to work in sawing and machining. Clogging of saw with latex can easily be eliminated by dabbing of saw blade with fuel oil.
- Though the quality and durability of rubber wood is high, one major advantage remains that it is still affordable and is not as expensive as some other woods are. So u get a good quality product and that too at an affordable price.
