DuPont unveils electric and hybrid vehicle solutions at Auto Shanghai 2019

DuPont’s polymers can replace metals used in EVs to meet challenges facing increased EV adoption

DuPont Transportation & Advanced Polymers (T&AP) has introduced a series of applications from its innovative electric and hybrid vehicle solutions portfolio during Auto Shanghai 2019.

The anticipated release of practical applications is the first since the company announced its AHEAD (Accelerating Hybrid-Electric Autonomous Driving) initiative launched last September. Designed to bring customers solutions and material capabilities, AHEAD promises varied applications in vehicle electrification, autonomy, connectivity and associated infrastructure.

Critical innovation challenges for EV adoption include thermal management, safety, NVH (noise, vibration and harshness), lightweighting, connectivity, sensing and control, durability and charging infrastructure must be solved in the value chain. AHEAD was developed to support OEMs and address their transformation challenges.

DuPont’s Zytel XT70G35HSL provides excellent features for metal replacement, including high temperature resistance, welding performance, NVH improvement, and lightweighting benefits, and can be blow moulded into complex air ducts. It helps to simplify the processing procedures, reduce overall cost and weight, and improve parts durability and reliability. Zytel® XT70G35HSL is already used by Dongfeng CACs, Geely resonators, Hyundai twin turbo T-joints, and BMWs I2ACACs.

DuPont Vespel parts offer exceptional tribological, thermal, chemical and mechanical properties and helps reduce cost by extending service life, improving energy efficiency and reliability, reduce NVH. Thinner, lighter Vespel SP-21D thrust washers replace metal needle bearings in AT for rear-drive vehicles. The AT’s superior response time delivers both exciting acceleration and a quiet, leisurely experience depending on the driver’s desire – while still improving fuel efficiency.

DuPont Molykote Noise Reduction Greases G-1056, G-1057, G-1067 are high performance lubricant greases with excellent NVH reduction, ultralow oil bleed, reduced friction wear, contamination and corrosion, compatible with most plastics.

Molykote G-1056 Grease is widely used in automotive body and interior components such as power slider door rail, actuators, EPB. Molykote G-1057 Grease is a translucent grease, especially working for noise reduction at low temperature. Molykote G-1067 Grease is widely used for sunroof guide slide, dashboard buttons, electrical tail door, excellent lubrication performance on glass-fibre-reinforced plastics.

When the goal is reducing weight, improving strength, enhancing durability, increasing thermal performance or simplifying processing, DuPont Zytel HTN high-performance polyamide resin is a logical choice.

Zytel HTN can replace metal parts that must withstand high temperature tolerances (such as engine cooling, handheld devices, and non-halogenated connectors), while reducing total cost and weight through parts consolidation.

Particularly important to the rapidly growing FCEV market where parts need to perform better under critical conditions, Zytel HTN high performance polyamide can be applied in the structural components of the stack and to the cooling system components of the BOP (Balance of Plant).

These high-performance resins are available in specific grades that sustain high strength and stiffness over a wide range of temperatures, chemicals and moisture exposure.
