This matters because cross-linked silicone rubber cannot be physically recycled; landfilling or incineration wastes resources and pollutes. Chemical recycling closes the loop. Pilot plants (5,000 tons/year each) are now operational in Zhejiang and Shandong, processing waste from PV frames, medical devices, and industrial seals.

Breakthroughs stem from three advances: raw material purity (D3–D6 cyclic siloxanes <10 ppm, meeting USP Class VI and ISO 10993); processing improvements (platinum-cure stability, sterile filling); and policy support—the 14th Five-Year Plan for Medical Equipment explicitly encourages localization of critical biomaterials.

Policy support is robust. The Organosilicon Industry Clean Production Evaluation Index System, effective January 2026, mandates that new projects consume no more than 1.8 tons of coal equivalent and 8 tons of water per ton of DMC, and must install HCl recovery systems. The Ministry of Ecology and Environment has also listed organosilicon in its “Key VOCs Comprehensive Governance Catalog,” pu

While P-type modules traditionally used EVA encapsulants, N-type cells—requiring higher efficiency and reliability—increasingly adopt hybrid “POE + EVA + silicone” schemes. Organosilicon is used for junction box sealing, frame bonding, and edge protection, valued for its anti-PID properties, UV resistance, and elasticity across –50°C to 150°C. Leading module makers report 80–120 grams of silicone

This strategic pivot is driven by multiple factors. First, generic DMC faces intense competition, offering limited long-term margins despite recent price stabilization. Second, emerging sectors—new energy, electronics, healthcare—demand higher performance: flame-retardant silicones for EV battery packs, low-ionic silicone oils for semiconductor packaging, and biocompatible gels for implants. Thes

This trend offers dual benefits for China. First, import dependency continues to decline: net imports fell 12% year-on-year to 83,000 tons in 2025 and may reach full self-sufficiency in 2026. Second, domestic premium products are gaining substitution opportunities. High-end silicones for electronics and medical devices—long dominated by Shin-Etsu, Wacker, and Momentive—are now being reevaluated b

This effort received policy backing. The NDRC’s Guiding Opinions on Regulating Price Competition in the Chemical Industry (December 2025) stated: “Encourage industry associations to establish capacity warning and coordination mechanisms to prevent wasteful overexpansion.” Today, the CR8 (combined market share of top eight firms) stands at 81%. Integrated leaders, leveraging cost advanta

This shift stems from dual policy and market drivers. Starting January 2026, China’s Ministry of Finance eliminated export tax rebates for certain low-end organosilicon products, explicitly encouraging high-value exports. In response, companies accelerated product upgrading: functional silanes (e.g., aminosilanes, epoxysilanes), electronic-grade silicone oils, and medical-grade silicones now acco

In the electric vehicle (EV) segment, per-vehicle organosilicon usage has significantly increased. For mainstream lithium iron phosphate (LFP) and ternary battery packs, flame-retardant addition-cure liquid silicone rubber (LSR) is now essential for cell module sealing, battery cell potting, and coolant line bonding. High-end models now use 1.8–2.5 kg of silicone per vehicle—nearly double the amo

The core driver behind the price rebound lies in supply-side reforms. In November 2025, led by Hoshine Silicon Industry, 11 major monomer producers convened a meeting of actual controllers and reached a consensus on “coordinated production cuts and price stabilization.” Starting December 2025, they collectively reduced operating rates to below 70%, cutting DMC supply by an estimated 1 million ton
