Dimensional stability and dynamic young's modulus of tropical light hardwood chemically treated with methyl methacrylate in combination with Hexamethylene Diisocyanate cross-linker.

Chemical treatment is often used to improve the physical and mechanical properties of wood materials. In this study, wood polymer composites (WPC) were prepared from five types of tropical wood species by impregnating the woods with methyl methacrylate (MMA) combined with a cross-linker hexamethylen...
