Summary
Furfuryl alcohol-based (FA) cell wall and methyl methacrylate-based (MMA) combination formulations were used to make wood polymer composites (WPC). Swelling gradients developed during preparation. Properties (density, hardness, water extractables, antiswell efficiency) gradients were observed along samples in 5 of the 7 treating formulations. Two cell wall treatments based on furfuryl alcohol did not show the gradients. The results suggest treating solution separations occurred during impregnation and the resulting nonhomogenious chemical produced the properties gradients. WPC made using the combination formulations based on MMA had properties which fell between cell wall and cell lumen formulations.
