What are the challenges faced by Automotive OEMs?

> Go towards Lightweight

The ever-stringent regional CO2 regulations in all regions are pushing hard the car weight reduction. Polymeric materials are a great asset to vehicle weight saving.

> Reduce Emissions

Concern about people health is leading to stricter regulations on emissions and odor reduction for automotive parts. Optimized raw materials from polymer to fillers and additives are required to comply with the harsher automotive requirements.

> Improve Durability and Aesthetic Added Value

End-consumers are more and more demanding for the overall performance and aesthetics of their first and second-hand cars. In addition, long-term perceived quality and comfort are seen as added values resulting in deeper attention to secondary properties such as non-stickiness / blooming of plastic parts.

> Optimize Cost in use

Cost remain a very important driver in the automotive market. Regulatory requirements to reduce CO2 remissions and consumers’ demand for additional high-end features keep the pressure on automakers which are seeking cost in use optimized solutions.
