Kapur
Species profile
The wood varies from red brown to pink brown. Camphor smell. Presence of thin resin veins. It has clearly demarcated sapwood. The grain is straight or interlocked and the texture is medium. Density at 12 % moisture content: 0.74 g/cm3.

The blunting effect is normal to fairly high; peeling is reported to be good and slicing is not recommended or without interest. Nailing is good but pre-boring is necessary. Gluing is correct. Possible oxidation in contact with iron. Resin exudation sometimes troublesome in gluing. It dries slowly. Possible resin exudation during kiln drying.

Kapur is very durable to durable to fungi and is durable to dry wood borers; sapwood demarcated (risk limited to sapwood).

Kapur can be used for several applications such as:
• interior: e.g. furniture, veneer, flooring, stairs, boxes and crates, formwork, joinery, tool handles
• exterior: e.g. wood frame house, paneling, bridges, heavy carpentry, joinery, vehicle or container flooring

Staining of runoff waters.
