Species: Kempas

« Back to species

Species profile
The wood is red brown. It is pink when freshly sawn, weathering to orange-red or yellow-brown. Frequent concentric layers of phloem. It has clearly demarcated sapwood. The grain is straight or interlocked and the texture is coarse. Density at 12 % moisture content: 0.88 g/cm3.

The blunting effect is 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. It dries slowly. Frequent concentric layers of phloem induces drying heterogeneousness and may cause wood damages. Medium hardness.

Kempas is durable to fungi and is susceptible to dry wood borers. Its treat ability is considered as low. However, according to some literature references, it would be easy to treat.

Kempas can be used for several applications such as:
• interior: e.g. flooring, sliced veneer, industrial or heavy flooring
• exterior: e.g. exterior joinery, sleepers, heavy carpentry, vehicle or container flooring
