The silicone in heavy machinery market size is expected to see strong growth in the next few years. It will grow to $2.53 billion in 2030 at a compound annual growth rate (CAGR) of 8.9%. The growth in the forecast period can be attributed to increasing investments in smart grid infrastructure, rising demand for high-temperature resistant materials, expansion of electrification projects, growing adoption of advanced insulation solutions, increasing focus on equipment lifespan optimization. Major trends in the forecast period include increasing adoption of high-performance silicone sealants, rising use of silicone in electrical insulation systems, growing demand for heat-resistant elastomers, expansion of silicone applications in switchgears, enhanced focus on long-term material durability.

The expanding automotive industry is expected to drive the growth of the silicone in heavy machinery market going forward. The automotive industry includes the production and sale of vehicles such as cars, trucks, and motorcycles, along with related services like maintenance and repair. Silicone is widely used in automotive heavy machinery for gaskets, seals, and insulating components due to its heat resistance and durability. For example, in January 2023, MarkLines Co., Ltd., a Japan-based automotive industry portal, reported that US new vehicle sales rose by 22.8% from May 2022 to May 2023, reaching 1,374,910 units, and increased by 1.39% from April 2023 to May 2023. Therefore, the growth of the automotive industry is driving demand for silicone in heavy machinery.

Leading companies in the silicone in heavy machinery market are focusing on advanced silicone 3D printing materials to produce highly durable, flexible, and custom-engineered components for heavy-duty industrial equipment. Silicone 3D printing enables rapid manufacturing of seals, gaskets, vibration-damping parts, and protective housings, improving operational efficiency and reducing machinery downtime. For instance, in July 2025, Stratasys Ltd., a US-based additive manufacturing company, in collaboration with Shin-Etsu Chemical Co., a Japan-based silicone producer, introduced P3 Silicone 25A. This industrial-grade 3D-printable silicone, compatible with the Stratasys Origin platform, offers true silicone properties such as high thermal resistance, flame retardancy, and long-term durability. It allows heavy machinery manufacturers to create complex, customized parts without traditional molding, enhancing production efficiency and accelerating component replacement cycles.

In May 2025, Trelleborg AB, a Sweden-based polymer technology company, acquired Sico Gesellschaft für Siliconverarbeitung mbH for an undisclosed amount. This acquisition aims to strengthen Trelleborg’s silicone rubber offerings by integrating Sico’s engineered extrusion and molding capabilities, including silicone tubes, hoses, and profiles, thereby expanding its portfolio of silicone rubber components for industrial, construction, automotive, and other applications. Sico, based in Germany, develops and manufactures a range of extruded and molded silicone rubber products.
