Cost-effective and sustainable production of coated parts facilitated by conductive nylon grade
The switch to a conductive grade of DuPont™ Zytel® nylon for the manufacture of lighting fixtures has helped Philips Lighting B.V. of Winterswijk (the Netherlands) achieve its aesthetic, production and sustainability requirements and has resulted in the approval of Zytel® CDV for future Philips lighting applications. Due to the nylon’s inherent conductivity, the injection-moulded end caps for the X-tendolight range of luminaires from Philips lend themselves to the same powder coating process as used for the light’s steel housing. This facilitates a closer colour match between components, eliminates the need for wet painting that contains hazardous solvents and greatly simplifies the manufacturing process.
