Abstract :

The multi layered flat pressed wood plastic particle boards (WPPB) were prepared by using the plantation timber of poplar spp (poplus deltoides) with poly vinyl chloride (PVC). Different proportions of PVC were mixed with the wood particles for the manufacture of WPPB; the better physical, mechanical biological properties were achieved in the 40%of PVC as per the relevant standards. In order to improve the fungus resistance properties of the WPPB, 3% to 5% of neem oil (Azadirachtin) was incorporated in the adhesive system as a glue line poison based on the weight of the urea formaldehyde resin. The samples were exposed 3 months for white rot Fungus by Kolle flask method. The 5% neem oil mixed WPPB boards were found that resistant to white rot fungus (Polyporous versicolor).
