The wheel forks utilize a long carbon fiber-reinforced nylon 6/6 composite, while the wheel hub comprises long carbon fiber-reinforced thermoplastic polyurethane.

Orange Nylon Colorants for High-Voltage Electric Vehicle (EV) Connectors The electric vehicle (EV) industry is growing rapidly as governments worldwide encourage sustainable energy. This is where Avient’s orange nylon colorants can help. Its portfolio of OnColor™ polymer colorants was developed to improve the heat and long-term color stability of cautionary orange polymers for high-voltage EV connectors, offering the following benefits: • Long-term fading resistance in thermal aging tests at up to 130°C for 1,000 hours, • No migration, excellent processing stability • Lower corrosion risk vs. typical comparable colorants • No impact on flame retardancy and limited adverse effects on essential mechanical characteristics, including flexural and impact strength Avient’s orange nylon colorants are available in several validated RAL, Pantone, and JPMA orange shades for compounding, injection molding, and extrusion.

For ASTM G21-15, most polymer compounds also exhibited marginal or no change in fungal growth with the added texture, except for nylon-6; trace growth (rating = 1) was observed on the smooth surface while heavy growth (rating = 4) occurred on the textured sur- face. Control samples (top row) are shown for comparison to samples post-incubation and washing (bottom row) TABLE 1 Summary of ASTM G21 results for initial susceptibility screening of untreated resins/compounds Fungal growth Resin/compound 4 = Heavy growth (61%– 100% coverage, fail) TPE, 6 formulations 3 = Moderate growth (31%–60% coverage, fail) Poly(urethane), 2 formulations 2 = Light growth (11%– 30% coverage, fail) Nylon-6,10, PBT, poly(amide) elastomer, ABS, 3 formulations, reinforced Nylon, 2 formulations 1 = Trace growth ( CFU, colony-forming unit; ZPT, zinc pyrithione 6 ZANDER ET AL.
