【Abstract】 With circumstance protection,the traditional heat stabilizer for PVC such as lead salt was limited. Some new heat stabilizers were exploited such as rare earth, organic antimony, autunite/zinc compounds, hydrotalcite and so on. They aren’t almost poisonous. They have good effect of heat stabilization and moderate price.They will be regarded and take the place of traditional heat stabilizers,and be new kinds of heat stabilizers for PVC.更多还原
