In addition to reinforced ribs, the piping groove for securing the seat cover in place as well as numerous holders and guides, for example, for seat ventilation and cable holders, are integrated into the component. The clips to attach the seat shell are also directly injected. “The shell can be assembled easily and quickly without screws using the clips, and disassembled again for servicing purposes. The clips are highly stable and meet all relevant safety requirements,” adds Sontag. Solvay and automotive component manufac-
turer Magneti Marelli have developed a thermo- plastic steering knuckle prototype. The steering knuckle’s complex geometry was designed to maximise the properties provided by Solvay’s thermoplastic compounds and injection moulding materials. It showcases compression moulding and overmoulding processes and the combination of Solvay’s Amodel PPA thermoplastic compound and Evolite PPA thermoplastic composites, which are temperature capable products developed specifi- cally for automotive functional applications. Solvay adds that this development highlights how novel high-performance materials, short cycle time processing methods and a smart part design can be combined to result in structural performance, function integration and weight saving. “This prototype is the first of its kind in the field
of suspensions,” says Gerald Perrin, Global Automo- tive Director at Solvay Composite Materials Global Business Unit. “By using promising materials and processing technologies we were able to combine high performance thermoformed laminates with injection moulding to create complex and non- conventional geometries. This combination enabled the design of a functionally integrated component including co-moulded structural sleeves.” PolyOne has developed OnColor RC Environ- mental Black masterbatch as a carbon black suitable for use in automotive applications. Derived from end-of-life tyres, this new colour concentrate

is a sustainable alternative to those based on virgin carbon black. OnColor RC Environmental Black is made using Bolder Black, a reclaimed version of carbon black made from scrap rubber. It creates a smaller carbon footprint than virgin carbon black because it uses 90% less water and 61% less electricity while emitting 90% less carbon dioxide in its manufacturing process. When used in place of traditional carbon black, OnColor RC Environ- mental Black maintains expected performance levels in plastics. It passes REACH and RoHS requirements and is available for use in multiple resins across a variety of industries and applica- tions, such as automotive.
