The time-dependent,shear rate-dependent and viscoelastic behavior of PVC plastisol with ultrafine calcium carbonate filled were obtained with time sweep,step-shear-rate sweep and frequency sweep methods.Thixotropic properties of this plastisol were characterized.From the experimental results,this plastisol is a viscoelastic thixotropic system with yield stress,and calcium carbonate improves the thixotropic properties after surface modification.
