Silicone rubber prices in Germany, the highest-cost reporting region, rose 7.0% in H1 2026, recovering from USD 5.70/KG in Q1 to USD 6.10/KG by Q2 as silicon metal feedstock firming and accelerating electric vehicle and medical device sector demand reversed the H2 2025 Chinese overcapacity-driven softening. Globally, the average rose from USD 4.247/KG in Q1 to USD 4.545/KG in Q2, a 7.0% gain. For H2 2026, a global average of USD 4.60-5.00/KG is expected, with continued firming on Middle East silicon supply disruptions and growing EV, electronics, and medical device sector demand.
Silicone rubber is an elastomeric material produced from polydimethylsiloxane polymer chains crosslinked by peroxide curing, addition curing using platinum catalysts, or condensation curing systems, yielding a material with exceptional thermal stability across a wide temperature range from below minus fifty to over two hundred degrees Celsius. The largest pull comes from automotive applications, where silicone rubber gaskets, seals, hoses, and vibration dampers provide heat resistance and durability in engine and exhaust proximity components. Additional demand comes from medical device and implant manufacture exploiting biocompatibility and sterilisation resistance, electronic component encapsulation and insulation, construction joint sealing and waterproofing, food-contact cookware and bakeware, and personal care and hair styling tool applications. Silicon metal, methanol, and specialty chemical intermediate costs, automotive and electronics sector demand, and regional polymerisation capacity all feed into the price.
The balance of supply and demand for silicone rubber through H2 2026 leans moderately firm. Silicon metal feedstock costs firmed from Middle East quartz and reductant supply disruptions and Chinese production discipline improvements. Automotive EV component, medical device, and electronics encapsulant demand is growing strongly with accelerating clean energy transition activity.
The main upside risk is a sharp silicon metal and methanol cost increase alongside accelerating EV battery thermal management and medical device silicone demand. The main downside risk is renewed Chinese silicone rubber capacity additions and export surplus that maintains competitive downward pressure on global prices.
