Automotive Silicone Market Report 2026

The automotive silicone market size has grown strongly in recent years. It will grow from $7.93 billion in 2025 to $8.55 billion in 2026 at a compound annual growth rate (CAGR) of 7.9%. The growth in the historic period can be attributed to automotive production growth, demand for heat-resistant materials, use in engines and electronics, safety compliance, material durability requirements.

The automotive silicone market size is expected to see strong growth in the next few years. It will grow to $11.41 billion in 2030 at a compound annual growth rate (CAGR) of 7.5%. The growth in the forecast period can be attributed to electric vehicle penetration, battery thermal management needs, lightweight vehicle design, advanced electronics integration, sustainability-driven material adoption. Major trends in the forecast period include increasing use of lightweight materials, growth in ev-specific silicone applications, rising demand for thermal management, expansion of sealing and bonding uses, focus on vehicle durability.

The increasing demand for fuel-efficient vehicles is anticipated to drive the growth of the automotive silicone market in the coming years. Fuel-efficient vehicles are those that provide better mileage per gallon compared to less efficient models. Automotive silicones play a crucial role in reducing vehicle weight, which leads to lower emissions and improved fuel efficiency. For example, in July 2023, the International Energy Agency, a France-based autonomous intergovernmental organization, reported that over 2.3 million electric cars were sold in the first quarter of 2023, marking a 25% increase from the same period in 2022. By the end of 2023, total sales are projected to reach 14 million, indicating a 35% year-on-year increase, with growth expected to accelerate in the latter half of the year. Consequently, the rising demand for fuel-efficient vehicles is propelling the growth of the automotive silicone market.

Major companies operating in the automotive silicone market are emphasizing technological advancements, such as insulation covering material solutions, to improve vehicle performance, reliability, and safety while complying with strict regulatory standards for electrical insulation and thermal management. Insulation covering material solutions are high-performance silicone-based materials engineered to provide electrical insulation, heat resistance, and protection in automotive applications. For instance, in March 2023, Shin-Etsu Chemical Co. Ltd., a Japan-based chemical company, developed a new silicone rubber, KE-5641-U, specifically designed for molding and ideal for use as an insulation covering material for high-voltage automotive cables. Its high withstand voltage enables thinner insulation layers, delivering superior insulation performance, improved cable flexibility, and the development of thinner, lighter high-voltage cables.
