In this work PVC plastisol rotational molding formulations were characterized as a function of processing conditions. Temperature sweep runs in the 60 to 220°C range suggest the presence of different stages in the solidification process, marked by the crossover of storage ( G ′) and loss ( G ″) moduli. Viscoelastic properties as a function of time were measured at different processing temperatures (in the 80 to 220°C range). Ultimate strength, ultimate elongation, and solvent resistance of the formulations after processing were also measured to evaluate performance.
