Wood Technical Fact Sheet
East African Satinwood
Other Common Names: Olon dur (Gabon), Munyenye (Uganda).
Distribution: Widely distributed in the equatorial forests, occurring up to elevations of 8,000 ft.
The Tree: Very variable, depending on site, may reach a height of 95 to 115 ft and more; bole usually straight and cylindrical; trunk diameters 2 to 5 ft.
General Characteristics: Heartwood bright or pale yellow darkening slightly on exposure; sapwood narrow, somewhat lighter, barely distinguishable. Grain interlocked giving a stripe figure; texture medium to fairly coarse; luster rather high; has a sweet scent when freshly sawn that does not persist.
Weight: Basic specific gravity (ovendry weight/green volume) very variable 0.55 to 0.83; air-dry density 42 to 64 pcf.
Mechanical Properties: (First set of data based on the 2-in. standard; second and
third sets on the 2-cm standard.)

Drying and Shrinkage: Air-seasons rapidly with little degrade, some tendency, though, to warp. Kiln schedule T3-C2 is suggested for 4/4 stock and T3-C1 for 8/4. Volumetric shrinkage green to ovendry about 11.5%.
Working Properties: Working characteristics variable, difficult to hand plane, high feed speeds in power sawing are suggested, can be dressed to a good finish, difficult to glue, has good steam-bending properties.
Durability: Not durable, sapwood liable to borer attack.
Preservation: Heartwood is rated as resistant to preservative treatments; sapwood permeable.
Uses: Fine furniture and cabinetwork, flooring, paneling, veneer, turnery.
