Common Name(s): Rubberwood, plantation hardwood, parawood, Malaysian oak
Scientific Name: Hevea brasiliensis
Distribution: Native to Brazil, but extensively cultivated in tropical regions, especially in Asia
Tree Size: 75-100 ft (23-30 m) tall, 1-3 ft (.3-1 m) trunk diameter
Average Dried Weight: 595 kg/m3 MC12%
Shrinkage: Radial: 2.3%, Tangential: 5.1%, Volumetric: 7.5%, T/R Ratio: 2.2
Color/Appearance: Heartwood naturally a light blonde to medium tan color, sometimes with medium brown streaks. Sapwood not distinct from heartwood. Color tends to darken slightly with age. Frequently colored or stained when used in furniture construction.
Grain/Texture: Grain is straight, with a somewhat coarse, open texture. Low natural luster.
Rot Resistance: Rubberwood is perishable, and has very little natural resistance to decay. It is also susceptible to fungal staining and insect attacks.
Workability: Easy to work with both hand and machine tools. Rubberwood tends to warp and twist in drying, though it is fairly stable in service once seasoned. Glues, stains, and finishes well.
Odor: Rubberwood has an unpleasant sour odor while being worked, especially when green, which subsides upon drying.
Common Uses: Furniture, cabinetry, interior millwork, kitchen woodenware (cutting boards, knife blocks, etc.), and other small, specialty wood items.
Comments: Despite its common name, rubberwood isn’t any more elastic or soft than comparable hardwoods of similar density/weight—the name is derived from its use on rubber plantations, where the sap is harvested as a natural source of latex. Rubberwood, The Wood Database, 2024
