Feasibility study on three furfurylated non-durable tropical wood species evaluated for resistance to brown, white and soft rot fungi
Furfurylation can protect non-durable wood species against biological degradation, but the method used today cannot fully protect the heartwood of Scots pine due to insufficient penetration. In order to test alternative wood substrates for furfurylation, three Malaysian grown wood species (Kelemp...

| Summary: | Furfurylation can protect non-durable wood species against biological degradation, but the
method used today cannot fully protect the heartwood of Scots pine due to insufficient
penetration. In order to test alternative wood substrates for furfurylation, three Malaysian grown
wood species (Kelempayan, Rubberwood and Sena) were furfurylated and subjected to soil
block decay testing. Their performance was compared to furfurylated Scots pine and furfurylated
Beech modified using the same process. In addition, treatment characteristics were evaluated.
One of the species tested, Kelempayan, seems to be a promising substrate for furfurylation.
Kelempayan is easy to impregnate in both sap- and heartwood, and a 50% higher weight gain
was reached using equivalent amounts of impregnation solution compared to Scots pine. Sena,
Rubberwood and Beech returned weight gains 40-60% lower than Scots pine. Decay protection
was largely comparable at equivalent weight percent gains for all wood species tested, although
differences appeared. Generally, a weight gain of approximately 25% by furfurylation seems to
offer good protection in the chosen soil block test. |
