The Use of Engineering Plastic Compounds on New Energy Veichle

The use of modified plastics in new energy vehicles, particularly for interior and exterior components, is extensive due to their contribution to weight reduction, durability, aesthetic appeal, and safety. Here's an overview of these materials and their applications： 

Interior Components

1.     Polypropylene (PP): Modified polypropylene is widely used in automotive interiors due to its lightweight, low cost, and good processability. It's commonly found in dashboard components, door panels, and carpet backing.

2.     Acrylonitrile Butadiene Styrene (ABS): ABS is a popular thermoplastic with good toughness, hardness, and dimensional stability, making it suitable for center consoles, air vents, and interior trim.

3.     PC/ABS (Polycarbonate/Acrylonitrile Butadiene Styrene Blend): The PC/ABS blend combines the high strength of polycarbonate with the processability of ABS, ideal for dashboards, door panels, and headliners.

4.     Thermoplastic Polyurethane (TPU): Known for its excellent wear resistance, chemical resistance, and flexibility, TPU is often used for soft-touch components like steering wheel covers, seat upholstery, and airbags.

Exterior Components

1.     Polycarbonate (PC): PC's high impact strength and transparency make it a choice material for front headlight covers, tail lights, and other translucent parts.

2.     Polybutylene Terephthalate (PBT): With good mechanical properties and chemical stability, PBT is used for bumpers, exterior mirror housings, and more.

3.     Nylon (Polyamide, PA): Nylon is favored for its outstanding mechanical properties and heat resistance, ideal for grilles, door handles, and fan blades.

4.     Polyphenylene Sulfide (PPS): PPS stands out for its exceptional heat resistance and chemical stability, suitable for high-heat-resistant exterior parts like exhaust system components.

These materials not only meet the performance requirements such as heat resistance, impact resistance, and aesthetics but also contribute to the vehicle's overall energy efficiency by reducing weight. As the new energy vehicle sector evolves, we can expect the development of more innovative plastic materials and composites to meet higher performance and sustainability standards.
