Última Durability of Thermoplastic Elastomers for Marine Applications 5 Bardin, Antoine. Thermoset elastomers are currently used for watertightness applications on marine structures, due to their interesting elastic properties and their important chemical resistance. However, thermoplastic elastomers (TPEs) represent an interesting alternative in an industrial context being increasingly restrictive toward chemical risks. In order to determine their behaviour in marine environment, hydrolytic and oxidative ageing of several TPEs was investigated. Degradation was particularly assessed with molecular chain scission measurement. Based on these data, a hydrolytic kinetic model predicting scissions was developed, including the autocatalytic effect as well as the use of a hydrolytic stabilizer. Meanwhile, characterization of mechanical properties...

A hydrolytic kinetic model predicting chains scissions of a polyurethane elastomer (TPU) containing an anti-hydrolysis agent (stabilization via carbodiimide) was developed. This model is based on four components: uncatalysed hydrolysis, acid-catalysed hydrolysis, carboxylic acid dissociation and competitive carbodiimide-based deactivation of acid. Protons were considered as the key catalyst responsible for the hydrolysis. Model parameters were determined by fitting experimental data measured on unstabilized and stabilized TPUs, aged in immersion from 40 to 90 °C. Scission kinetics were predicted for immersion and 50% relative humidity conditions, from 10 to 100 °C. Structure-failure property relationships were also investigated, between molar mass and...
