The PVC plastisol is widely applied to the production of synthetic leather, advertisement cloth, awning cloth and the like as a binder. PVC plastisols are generally suspensions of PVC particles, and the adhesion between particles has a great influence on the later peel strength. The conventional PVC plastisol is formed by stirring and dispersing PVC paste resin, a plasticizer, a stabilizer, a filler and the like. In order to increase the solvating power of PVC plastisol, plasticizer is a common additive, but the solvating power of the plasticizer to PVC is limited, and even if the viscosity of glue is similar, the phenomenon of poor peel strength still often occurs in the production process. Although many manufacturers age the PVC plastisol to improve the stability of peel strength, some PVC plastisols also exhibit poor peel strength.

The traditional method for measuring the stability of the PVC plastisol is to coat the PVC plastisol on corresponding products, take the products coated in different time periods, and test the peel strength of the products respectively in a peel strength tester. However, this method requires coating PVC plastisol onto a designated product, and then testing is performed, and if the peel strength stability after testing is not good, this means that the stability of the batch of PVC plastisol is not good.
