A process patented in England isolates the resin from the wood, this resin is then reacted with aldehydes in situ to form thermoplastic or thermosetting resins, giving a cheap molding powder. This promises the development of a wet-forming or dry-forming process for making fibreboard from the wood[

The heartwood is red or reddish-purple to dark brown, with lighter veins; it is clearly demarcated from the 2 - 6cm wide band of dirty white or gray coloured, resin-streaked sapwood. The grain is uniformly straight; the texture medium to coarse; not lustrous, although quarter-sawn lumber shows a pleasing fleck as a result of resinous deposits; it is tasteless and althoughthere is an unpleasant odour when green, the seasoned wood is either odourless or has a slight odour described as rancid, sour, or like creosote by different observers. The wood is hard, heavy, stiff, strong; durable to very durable in the soil, being resistant to fungi, dry wood borers and termites. It seasons slowly, with a high risk of checking and distortion; once dry it is moderately stable in service. Although it is hard, the wood works easily with machine and hand tools except that gum collects on the cutting edges of the tools. It polishes reasonably well after filling; stains readily with both oil and spirit stains; turns well; it usually splits straight and clean; but does not take nails satisfactorily. The wood is exceptionally well suited for use as transmission poles, flagpoles, and posts. Its good strength and durability qualify the timber for railway ties, shoring, bridge timbers, and mine timbers. In building construction it is used for foundations, sills, joists, framing, roofing, siding, and veranda posts. The high resin content of the wood makes it an excellent flooring material in chemical factories, mills, and warehouses[
