Gelling curves of PVC plastisols (50 phr plasticizer) with
Plasticizers are used to make PVC flexible so it can be used as a geomembrane for containment purposes. Plasticizers can migrate from PVC geomembranes over time because of contact with air,...

Test methods for gelation of PVC plastisol - ScienceDirect
This will be the subject of future study. The total amount of plasticizer also influences the gelling tempera- ture. In industrial processes, the plasticizer concentrations of plastisols may range from 40 to 100phr. In this experiment, two plasticizer concentrations were used: 80 and 100 phr. The results are shown in Fig. 3.
- Does plasticizer concentration affect gelation and fusion of PVC plastisols?
- The influence of plasticizer concentration in the processes of gelation and fusion of PVC plastisols has been studied by viscoelastic oscillatory tests.
- What is the gelation temperature of PVC/DINP-CD plastisols?
- As can be seen Fig. 5, complete gelation of the PVC/DINP-CD plastisols occurred at 158 °C, a gelation temperature that was slightly higher than that of the PVC/DINP plastisol (150 °C). Gelation of the PVC plastisols was delayed upon addition of Bz- β -CD particles, possibly because of the decreased interaction of the PVC with the plasticizer.
- How to test gelation properties of PVC plastisol?
- Printed in Northern Ireland 316 Wang Guoquan, Chen Yiaoting Gelation properties of PVC plastisol can be tested by a number of methods which can be divided into two groups: dynamic methods and static methods.
- Do Plastisol concentrations affect gelation and fusion mechanisms?
- Some plastisols of PVC with different concentrations of plasticizer have been used to study the influence of concentration in the gelation and fusion mechanisms. The data obtained have been used to prove the validity of the theoretical model, and obtain its characteristic parameters. 3. EXPERIMENTAL 3.1. Sample
- What are the dynamic methods of plastisol gelation?
- The dynamic methods involve tests using the Brabender plastometer,2 rotating viscometer,3 and rheometrics mechanical spectrometer.4 All of the dynamic methods mentioned above determine the increase in viscosity of PVC plastisol during the gelation process in the presence of an external force.
- How much plasticizer is used in Plastisol gelling?
- The total amount of plasticizer also influences the gelling tempera- ture. In industrial processes, the plasticizer concentrations of plastisols may range from 40 to 100phr. In this experiment, two plasticizer concentrations were used: 80 and 100 phr.
