It is with great pleasure that we invite you to participate and present a paper at the Polymers Weathering Conference – a collaborative Event of the 11th EWS (XXXIIIrd Colloquium of Danubian Countries on Natural and Artificial Ageing of Polymers) and  Bandol Conferences, to be held in Lyon, France, September 22–24, 2026.

Launched in 1967 by four relevant institutes from Austria, Czechoslovakia, Hungary and Yugoslavia, the Colloquia of Danubian Countries have been the only exclusive meetings in the field of natural and artificial weathering of polymers. Relaunched as EWS they have attracted a broader scope of attendees.

In the tradition of these colloquia, the EWS is a meeting point for experts from industry and academia to learn from each other.

Important topics will be:

– Weathering of Polymeric Products – Plastics, Sealants and Coatings

– Determination, Simulation and Effects of Relevant Climatic Quantities

– New Test Procedures and Devices

– Weathering Reference Materials Analysis of Polymer Degradation

– Service-Life Prediction
