Chery Automobile’s soon to be launched A3CC sports coupe features three applications of SABIC Innovative Plastics’ materials: the first Noryl GTX resin front fenders used by a Chinese automotive OEM; a fuel filler door, also molded from Noryl GTX resin; light weight front and rear energy absorbers made from Xenoy resin and an undertray, molded from Stamax long glass-filled polypropylene (LGFPP) compound.
Front fender. Chery is the first Chinese OEM to use conductive Noryl GTX resin for a mass-produced fender. Replacing steel body panels with Noryl GTX resin enabled Chery to cut fender weight by more than 50% vs. steel (1.37 kg vs. 2.80 kg) while delivering better low-speed impact durability than steel. Noryl GTX resin can be online painted along with the metal Body-In-White (BIW), avoiding the need for secondary operations and ensuring a perfect color match. Further, this conductive resin does not require a primer step prior to painting.
Fuel-filler door. This part is traditionally molded and painted by the component supplier, potentially causing color mismatches with the body. Molding this part from Noryl GTX resin enables it to be painted online along with the rest of the BIW. This streamlined approach avoids quality issues and enhances aesthetics.
Energy absorbers and undertray. The A3CC’s front bumper will incorporate an energy absorber made with Xenoy resin and an undertray molded with Stamax LGFPP compound. These components—which meet European Union (EU) 2003/102/EC Phase II lower leg pedestrian protection requirements and Economic Community of Europe (ECE) and Federal Motor Vehicle Safety Standards (FMVSS) impact test requirements for low speed vehicle damageability—form a globally compliant bumper system. The rear bumper system will also incorporate an energy absorber made with Xenoy resin, and meets ECE and FMVSS low-speed vehicle damageability requirements.
Overall benefits from SABIC Innovative Plastics’ materials include weight-out for energy efficiency, part consolidation, design flexibility and system cost reduction from online painting.
