Color/additive masterbatch deployed in compressible exterior car panels


Additive technologies from PolyOne Corporation (Cleveland, OH) have enabled Citroën to launch the groundbreaking Airbump exterior protective panels on the new C4 Cactus passenger car.

The air-filled Airbump panels, manufactured from thermoplastic polyurethane (TPU), can compress up to 20 mm, and bounce back to shape in an instant. Citroën notes that this will reduce the cost of vehicle ownership by reducing damage due to everyday bumps and scratches, such as those from shopping carts or the doors of other vehicles.

Working closely with the Citroën design team, PolyOne developed a specialty OnColor Smartbatch color and additive system that allows the distinctive panels to meet stringent UV stability, appearance and durability requirements.
