PA-Tekolen by GRAFE is a color-stable, cost-effective color masterbatch for polyamides which even after 1,000 hours service at 130°C, reportedly still retain their warning effect without darkening. RAL2003 pastel orange is selected to identify plastic-sheathed, high-voltage, current-carrying components in E-mobility to warn of the dangers associated with this new technology. It offers processors considerable flexibility in meeting specific requirements and at the same time optimizes material consumption. It can be used for PA 6, PA 66 and glass fiber-filled & flame-retardant polyamides while maintaining mechanical material properties. Its flexible rate of addition enables distinctly better control over this “critical” color than do commercially available compounds. Its performance is based on a combination of highly thermally stable dyes with special heat stabilizers. Possible applications of PA-Tekolen include high-voltage connectors, insulation for high-voltage cables, cable conduits, charging sockets or fasteners for electric vehicles, while wiring harness clips.
