| Research Abstract |
For improving mechanical strength and weatherability of wood-plastic composites (WPC) with high wood loaded, mechanical strength was improved by plasticity additives made from woody chemical components. And, improvement of weatherability of WPC by ultra violet ray stabilizers (UVAs) and light stabilizers (LS) for plastic use was evaluated, and UVA mainly decreased color changes and LS reduced chalking. Furthermore, good depression effects for both color change and chalking were achieved by combination of UVA and LS.
