Wire manufacturers have long been trying to offer halogen-free, flame re ant cables made for high-end, direct current chargers and data cables i ny colors other than black and grey.

But the dream usually short-circuited — until now.

Chiangyu Electric, a leading Chinese wire and cable maker, recently rolled out the first line of ultra-white, custom-colored cables made from Flexible Noryl PVC resin from SABIC Innovative Plastics.

For years, Chiangyu Electric used PVC for its cable products, but was hamstrung in its efforts to substitute a material that not only provided non-halogenated flame retardance but also could be processed on its existing extrusion equipment to keep production costs down. Further hurdles: the material would have to have tensile strength, elongation, flexibility, heat aging, cold bending and custom color.

SABIC provided two new grades of Flexible Noryl resin that fit the bill: WCD801AU, designed for cable jacketing; and WCP821U, designed for molded cable components. Ultraviolet weathering tests performed at the company’s China Technology Center in Shanghai, per the ASTM D4459 standard, resulted in a color shift Delta E value of less than three after 300 hours of exposure to a CWF2 light source.

“Thanks to SABIC’s solution, our customers are very pleased with handsome, ultra-white cables which add a fresh and stylish look to their products, while also giving them extreme high performance,” said Sunny Wu, president, Chiangyu Electric.
