In this paper, plasticizer (DOP) was used to develop modified PVC composites. Through the change of DOP content, the change law of mechanical properties and thermal stability of PVC composites was observed. The results show that with the increase of DOP content, the plastic temperature of modified PVC composites decreases, but at the same time the mechanical strength of modified PVC composites decreases.
