Center National for Evaluation of Photoprotection

Bridge between research and industries

We assist companies, research organizations and innovation centers in their development, sustainability or analysis of polymeric materials

Offers, services and advice, the CNEP is at your service

Since 1986, the CNEP has supported you in understanding the aging phenomena of your polymer materials. Thanks to our expertise and our knowledge on chemistry and photochemistry, we can guide you in order to effectively control the durability or degradation of your products. In addition, our skills in plastic material analysis and our numerous scientific devices allow us to respond to your requests for characterizations or expert assessments of failures.

State-of-the-art aging and analysis equipment

Located in the Auvergne-Rhône-Alpes region near Clermont-Ferrand (France) on more than 1500m², our laboratory has one of the largest fleet of accelerated photo aging chambers for polymers, ventilated and climatic ovens as well as devices prediction of durability or more specific aging. The CNEP also has a wide range of physico-chemical analysis devices, including multiple spectrometers, microscopes, chromatographies and characterization devices.

Areas of activity and references worldwide

Our main areas of activity and expertise include the sectors concerned by the use and future of plastics: sports and spare-time activities, agriculture, packaging or transport. We are also present in the fields of electricity and telecommunications, medical and of course in all fields of research related to polymers. We are in contact with more than 450 local, national and international companies
