In this study Urea Formaldehyde (UF) were resins prepared, modified and non-modified to formation composites reinforced with waste sawdust particle, with consideration the urea purity as a main composite factors and formalin life span. these are directly contributing factors that influence on composites properties such as Thermal coefficient Resistivity and specific gravity. Plastic wood was prepared by used (Quercus, pear, Tectona, Fagus, Jew, Spruce, MDF) sawdust powder as reinforce phase with particle size less than ( |
