The CNEP: Your partner in photoaging & polymer analyses

How evaluating the sustainability of your polymers by the CNEP can help you improve the quality of your products.

Polymers play a central role in many industries, from packaging to automotive to aerospace. However, their widespread use raises concerns about their environmental impact and long-term sustainability.

Understanding and mastering the sustainability of polymers

The durability of polymers refers to their ability to maintain their performance and structural integrity throughout their life cycle, while minimizing their impact on the environment.<br> This includes their resistance to degradation due to various factors such as light, heat, chemicals and mechanical stress.

Sustainability assessment: a multidisciplinary approach

To assess the durability of polymers, CNEP uses a multidisciplinary approach combining laboratory tests, cutting-edge analyzes and perfect scientific knowledge of the chemical phenomena involved. This holistic approach allows for a comprehensive and accurate assessment of polymer durability.

1
Accelerated aging tests
These tests expose polymers to extreme conditions simulating the effects of time, such as exposure to UV rays, heat and humidity, to assess their resistance to degradation.
2
Analysis of physicochemical properties
This method analyzes changes in the physical and chemical properties of polymers over time, such as variation in molecular weight, crack formation, and loss of strength.
3
Correlation with natural aging(s)
Our scientific database and modeling are used to predict the long-term behavior of polymers based on various environmental and design factors.

Our commitment to sustainability

At CNEP, we are committed to supporting the development of sustainable polymers by providing reliable scientific data and recommendations to improve their performance and reduce their environmental impact. By collaborating with industry, researchers and regulators, we work to promote responsible use of polymers for a sustainable future.

La certification ISO 9001 - 2015

L'ISO 9001:2015 spécifie les exigences relatives au système de management de la qualité lorsqu'un organisme:

a) doit démontrer son aptitude à fournir constamment des produits et des services conformes aux exigences des clients et aux exigences légales et réglementaires applicables, et

b) vise à accroître la satisfaction de ses clients par l'application efficace du système, y compris les processus pour l'amélioration du système et l'assurance de la conformité aux exigences des clients et aux exigences légales et réglementaires applicables.

Toutes les exigences de l'ISO 9001:2015 sont génériques et prévues pour s'appliquer à tout organisme, quels que soient son type ou sa taille, ou les produits et services qu'il fournit.

Obtenir la certification ISO 9001:2015, c’est s’appuyer sur 8 principes de management :
• l’orientation client ;
• l’implication du personnel ;
• l’approche processus ;
• l’amélioration continue ;
• la gestion par approche système ;
• le leadership ;
• la prise de décision fondée sur des preuves ;
• le management des relations avec les parties intéressées.
