Studies on Weathering Modification and Light Stabilization of POM
摘要
Abstract
Weathering polyoxymethylene ( POM) materials modified with compounded hindered amine light stabi-lizers and ultraviolet absorbers were prepared ,and their mechanical properties and artificial accelerated aging behav -iors were tested and evaluated.It has been found that the retention of tensile strength ,elongation and notched impact strength can be improved to reach 103%、76.2% and 84.4%, respectively , and the color difference has decreased from 7.6 to 0.8,which is far better than the corresponding properties of POM without light stabilization modification .关键词
