Nano‐CaCO3 was used as nano‐scale filler and poly(1,2‐propylene glycol adipate) (PPA) was used as polymeric plasticizer in flexible poly(vinyl chloride) (PVC) sheets for the partial replacement of di(2‐ethyl hexyl) phthalate (DOP) in this paper. The effect of PPA and nano‐CaCO3 on restraining DOP migration was evaluated via extraction tests. The results showed that the introduction of nano‐CaCO3 can decrease the extraction rate of DOP in the PVC matrix. The tensile strength and elongation at break of CaCO3‐1/PPA‐20/DOP‐30/PVC were similar to those of DOP‐50/PVC, and CaCO3‐1/PPA‐20/DOP‐30/PVC exhibited the superior suppression of DOP migration compared with DOP‐50/PVC. Thermogravimetry analysis (TGA) indicated that the addition of nano‐CaCO3 effectively improved the thermal stability of the nanocomposites. Therefore, the combination of PPA and nano‐CaCO3 is an effective approach to suppress the migration of DOP.
