“Shift Toward Lightweight Shielding Materials”
- As automakers aim to produce more fuel-efficient and electric vehicles, there’s a strong push toward using lighter materials throughout the vehicle — and shielding components are no exception. Traditional metal-based shielding, while effective, adds significant weight to the vehicle. This is prompting manufacturers to explore alternatives like conductive polymers, coated fabrics, and advanced composites that can offer similar protection against electromagnetic interference (EMI) without the added weight. Lighter vehicles consume less energy, which is especially important for electric vehicles where range is a critical factor.
- In this context, lightweight shielding not only improves vehicle efficiency but also supports overall design flexibility. Automotive suppliers are investing in R&D to develop materials that balance performance, weight, and cost. This trend is particularly gaining traction in markets like Europe and Asia, where fuel economy standards are strict. As a result, demand for innovative, lightweight shielding materials is expected to rise significantly. This change marks a shift from functionality alone to performance with sustainability in mind.
- For instance, In March 2025, Continental AG introduced the UltraContact NXT tire, which incorporates up to 65% renewable, recycled, and ISCC PLUS mass balance certified materials. This tire exemplifies the company's commitment to sustainability and lightweighting in automotive components. The integration of lightweight materials in tire manufacturing contributes to overall vehicle weight reduction, enhancing fuel efficiency and performance. Continental's approach demonstrates how lightweighting strategies can be applied across various automotive components, not just in structural parts but also in accessories like tires.
