Efeito do envelhecimento e da geração de “whitening” no comportamento mecânico do PVDF
The polyvinylidene (PVDF) is a polymer with high chemical and mechanical resistence, for this reason is being largely used in the composition of flexible pipes used in petroleum production offshore, acting as sealing layer. One effect named whitening can appear in the material, being characterized …
