CNEP is a research center for durability prediction and failures analysis of plastics (polymer) materials. The increasing use of plastics in daily life and for high tech applications points out the necessity to improve their reliability. These materials can eventually fail during their service life and it is crucial to be able, like in medicine, to diagnose the cause of the failure and to suggest solutions to solve the problem. Plastic materials are made of polymer mostly associated with formulation products allowing to adjust their basic properties to special use they are made for (fillers, pigments, additives. .. ).
