For more than 20 years, CNEP has been applying the concepts of photochemistry to rationalise the behaviour of polymer materials observed during their lifetime.
Its approach, based on the precise knowledge of the chemical mechanisms of both degradation and stabilization of most polymer families, is today largely accepted at the national and international level.

The unique association of a well known French research laboratory developing fundamental research on polymer photoageing (LPMM) and a research centre (CNEP) connected with hundreds of companies working in all the fields of polymer applications has been generating a rich experience about the behaviour of polymer materials but also about their characterization in the solid state, in blend with various fillers and additives.

Next September 29th  and 30th, CNEP organizes a two days meeting devoted to the concepts of polymer degradation and to the experimental techniques ensuring both the prediction of the long term behaviour of polymers and the assessment of their degradation.
