Última Polychloroprene behaviour in a marine environment: Role of silica fillers ArchiMer Tchalla, Siwavi Tatiana; Le Gac, Pierre-yves; Maurin, R.; Creac'Hcadec, R.. Polychloroprene rubbers are widely used in marine structures and often filled with silica in order to increase mechanical properties. The presence of silica fillers leads to a complex degradation of the material. This study aims to understand the deeper degradation mechanisms involved when a silica filled polychloroprene is used in sea water. To do so, 4 polychloroprene rubbers filled with different amounts of silica (from 0 to 45 phr) were aged in natural sea water for 6 months at temperatures ranging from 25 to 60 °C. Moreover, a natural rubber with similar formulation was also considered in order to evaluate the role of the chlorine atom in the degradation. . The chemistry and mechanics of the rubber degradation were also studied. In the presence of... Tipo: Text Palavras-chave: Polychloroprene; Seawater; Silica filler; Hydrolysis.

In some industrial applications, bonding rubber coatings to metallic pipelines is a suitable solution to protect them from marine corrosion. This study deals with the long term behavior of such metallic coated pipelines in a marine environment. Two different approaches have been developed. The first focuses on degradation data of pipelines used for around thirty years in normal service conditions. As these bonded assemblies are different in terms of material formulations, manufacturing processes and aging conditions, statistical tools were used to identify homogeneous groups with identical aging mechanisms. Also, based on these results, the main degradation mechanisms of the rubber coating were established. The second approach focused on pipelines used...
