Abstract
Polymers are viscoelastic materials and the use of polymeric materials has grown on the world stage due to its good mechanical properties. In the oil area, the polymeric materials are often used in the manufacture of some of the layers that make up the flexible tubes. Dynamic Mechanical Analysis is an excellent method to obtain information about viscoelasticity since it measures the stiffness and damping of polymers as a function of temperature and frequency. The present work is concerned with the mechanical behavior of a polyvinylidene fluoride (PVDF) in tension. The polymer was tested on dynamic mechanical analysis (DMA). Analyzes were performed in two different manners. In the first, five different frequencies were set and the temperature was ranged from -20°C to 40°. Finally, four isothermal temperature steps were set and the frequency was ranged from 0.01Hz to 100Hz.
