The next "popular car" wins with new materials

As the range increases by 100 kilometers, the weight of the power battery increases by approximately 50kg. How can "weight reduction without compromising safety" be achieved? This is the unavoidable "weight paradox" in new energy vehicles. Data shows that if the overall weight of the vehicle is reduced by 10%, the range can be increased by up to 10%. However, the lightweight potential of traditional metal materials is nearing its limit. As car manufacturers meticulously calculate the "electricity consumption per 100 kilometers," the specific strength (strength, density) of materials becomes crucial.

In 2024, 72% of domestic new energy vehicle fire accidents were caused by battery issues. With the development of automotive intelligence and electrification, traditional metals are highly conductive, and engineering plastics have insufficient heat resistance, becoming bottlenecks. Whether it is the casing material of the battery pack or the interior decoration materials, materials with excellent flame retardancy, heat resistance, and impact resistance have become the "gatekeepers" ensuring passenger safety.

The detection accuracy of LiDAR requires the radome's dielectric constant to remain stable within a certain range, while the signal transmission of millimeter-wave radar requires materials with low dielectric loss. The touch screens of smart cockpits demand materials with high light transmittance and scratch resistance. The integration of material functions is redefining the intelligent experience of automobiles, and traditional plastics find it challenging to meet multi-performance coordination. How can intelligent driving be realized?

As global awareness of environmental protection increases, the recyclability and biodegradability of automotive materials have become new focal points. The European Union's Carbon Border Adjustment Mechanism (CBAM) will be fully implemented in 2026, and plans to include downstream products such as automotive parts in its taxation scope. China's "New Energy Vehicle Industry Development Plan (2021-2035)" clearly sets carbon dioxide emission targets, expecting a 70% reduction in vehicle carbon emissions by 2035 compared to 2020. How to achieve material greening and reduce production costs while meeting performance requirements has become a challenge that automotive companies must face.

High strength and high toughness coexist:Through toughening modification, plastics can significantly enhance impact resistance while maintaining a lightweight nature, meeting automotive safety requirements.

Enhanced flame retardancy and heat resistance:Add flame retardants and heat-resistant modifiers to ensure the stability of plastics under high temperatures or fire conditions, providing safety assurance for passengers.

Significant cost-effectiveness:Compared to metallic materials, modified plastics have a significant advantage in production costs and are easy to recycle and reuse, aligning with the concept of sustainable development.

High design flexibility:Plastic has strong plasticity, which can meet the design requirements of complex automotive structures and provide more possibilities for automotive styling innovation.
