Rubberwood — Hevea brasiliensis
Medium; the pale color, diffuse-porous structure visible under magnification, and characteristic diffuse growth rings point strongly towards Rubberwood, though similar plantation hardwoods share visual traits. confidence

Grain Pattern

Straight to shallowly interlocked with a medium to coarse texture and a subtle cathedral pattern on flat-sawn surfaces.

Color & Appearance

Light blonde to medium tan with a slight pinkish or yellowish tint; little distinction between heartwood and sapwood; darkens slightly with age and light exposure.

Hardness (Janka)

955 lbf (Medium)

Durability & Decay Resistance

Non-durable; susceptible to fungal decay, powderpost beetles, and termite attacks if untreated.

Value & Sustainability

Estimated Market Value
Moderately low, approximately $2.00 to $4.00 per board foot.
Wood Age Estimate
Estimated to be relatively recent, between 5 to 15 years old based on modern milling marks and uniform surface treatment.
Sustainability Status
Highly sustainable; harvested from plantation trees at the end of their latex-producing lifecycle, often certified by FSC.

Common Uses

Furniture, cabinetry, flooring, cutting boards, and interior joinery.

Geographic Origin

Native to the Amazon Basin in South America, but commercially cultivated extensively across Southeast Asia (particularly Malaysia, Thailand, and Indonesia).

Workability

Generally easy to work with both hand and machine tools, though it can occasionally tear out during planing of interlocked grain. Glues and finishes well.

Finish Recommendations

Takes stains, paints, and clear finishes (polyurethane, lacquer, oil) very well with minimal special preparation.

Notable Features

High dimensional stability after kiln drying; absorbs stains and finishes exceptionally evenly; requires chemical treatment after harvesting to prevent insect and fungal attack.
