Exterior components are large in area, technically demanding, and produced in high volumes; price movements in PP compounds, PC and the polyamides feed directly into material costs.
Weather-resistant materials: exterior parts use special compounds and transparent plastics with their own price dynamics.
Large components: bumpers and body parts need a lot of material – the price per kilo has a strong effect.
Broad material mix: from PP compounds to PMMA, very different plastics are used depending on the application.
