Dec 1, 1991Different grades of PVC resins and a variety of plasticizers are used to adjust processability and properties of plastisol. The plastisol, which is a dispersion of fine particles of PVC in plasticizer, is coated on a substrate and heated in an oven to gel and fuse. In the
The finished products are flexible PVC such as coated fabrics and surgical globes. Different plasticizers, because of the difference in solvent power, affect the process of gelation and

(a) Gelation in the more accessible parts of the resin [Fig. 5 (a) Fig. 6 (a)]: at the first stage, the sample is in the plastisol state (a suspension of particles in the plasticizer,
In this study, viscoelastic measurements permitted continuous monitoring of the changes in the G′ and G″ as a function of temperature during gelation and fusion. The

enhanced formation of PVC crystallites (crosslinking points in the gel). This effect of the plasticizer solubility on the gelation behavior becomes a key factor in our later discussion. 3.3 Equilibrium
This was the expected behaviour since gelation is a process dependent on time and temperature [10]; in this way if the heating rate decreases, the sample evidently has more time

Feb 15, 2007The second characteristic of plastisol is its gelation and its “fusion” under the effect of temperature (Nakajima and Harrell 2001). In the industry of PVC, the term of gelation does not translate a brutal transition between two
Foams are produced from plastisols, which are based on the suspension of the PVC resin in a plasticizer. Phthalates are the most used plasticizers in flexible PVC foam
