Resumo
The Plastisol is a fluid bulk based on PVC, mineral fillers, plasticizers, stabilizers and depending of its final application, a pigment and resins for adhesion providing. It can be produced by using two different types of mixers: The sigma and the cowles. This work studied what was the best mixer for producing the Plastisol and also evaluated the adhesion, viscosity and thixotropic properties gotten using these two producing processes. For a better understanding of adhesion, viscosity and thixotropic phenomenon, it was produced in the laboratory four different samples, each one with different producing process. It was prepared specimens of Plastisol for each producing process used, where the tensile strength was measured in a dynamometer for taking the force intensity and a rheometer for viscosity and thixotropic studies. This way was possible to evaluate what was the best producing process adopted.
