We have no more specific information for this species, but the general description of pulai timber is as follows:-

The heartwood is a cream white to a light yellow; it is not clearly demarcated from the sapwood. The texture is medium; grain straight, sometimes irregular or oblique; the aspect slightly lustrous. The wood is light in weight; soft to very soft; not very durable, being susceptible to fungi, dry wood borers and termites. It seasons rapidly with only a slight risk of checking or distortion; once dry it is stable in service. It works well with normal tools, though these should be kept sharp to avoid fuzzy surfaces; filling is recommended in order to obtain a good finish; nailing and screwing are poor; gluing is correct. The wood is suitable for uses such as boxes and crates, interior panelling and joinery, matches, furniture and moulding[
