Details:
The new energy vehicle (NEV) industry’s rapid growth is fueling demand for thermal conductive silicone, which is critical for battery thermal management, electronic component cooling, and sealing. In Q1 2026, global demand for NEV-specific thermal conductive silicone reached 80,000 tons, a 62% year-on-year increase. Each electric vehicle uses 5–8 kg of thermal conductive silicone for battery gap filling, heat sink bonding, and waterproof sealing. With global NEV sales expected to exceed 15 million units in 2026, demand for thermal conductive silicone will remain strong. High-performance thermal conductive silicone (2.0–4.0 W/m·K) commands a 30–50% price premium over conventional grades. Hongye Silicone, recognizing the market potential, expanded its high-thermal-conductivity silicone production line in Shenzhen in April 2026, increasing monthly capacity by 300 tons. The company’s products, including thermal conductive gap fillers, adhesives, and potting compounds, feature high thermal conductivity, low thermal resistance, and excellent adhesion to metals and plastics, making them ideal for NEV battery and electronic system applications.
