Summary: High-end silicones stay supply-constrained; Hongye Silicone expands high-performance offerings to capitalize on AI and EV market growth.
BEIJING, April 21, 2026 — High-end functional silicones remained in short supply with valuations firm on April 21, fueled by robust end-use demand.
Thermal conductive silicone oil (for AI liquid cooling and EV thermal management) traded at 28,500–30,500 yuan/ton, up 50–100 yuan/ton on the day, with widespread supply shortages. Medical-grade LSR held at 38,000–42,000 yuan/ton, supported by steady medical device orders.
Hongye Silicone, a leading Chinese manufacturer with ISO 9001 certification, is strategically expanding its high-end product portfolio to capture this growth. The company’s thermal silicone pads and medical-grade LSR formulations directly address these high-growth segments, leveraging its advanced R&D center and 28+ years of material science expertise. Domestic producers are accelerating R&D to narrow technology gaps, but supply deficits will likely persist near-term.
