1. Development status: domestic substitution is accelerating, and breakthroughs in high-end fields are significant
At present, China's silicone rubber industry has formed a competitive landscape of "leading by the head and breaking through in subdivisions". Leading companies such as Hosun Silicon Industry and Xin'an Shares have occupied 18% of the global market share in the field of high-temperature vulcanized silicone rubber (HTV) through vertical integration of the industrial chain. In 2024, the domestic photovoltaic installed capacity will exceed 600GW, directly driving the market size of RTV packaging materials to 14.5 billion yuan. Although international giants such as Dow Corning and Wacker occupy more than 30% of the high-end medical-grade liquid silicone rubber (LSR) market, domestic companies have achieved technological overtaking-the localization rate of biocompatible silicone has increased from 45% in 2020 to 58%, and the import dependence of high-phenyl silicone rubber has dropped from 68% to 41%.

Differentiated competition in subdivisions is prominent: small and medium-sized enterprises focus on emerging tracks such as 5G base station heat dissipation glue and semiconductor packaging glue. In 2024, the market size of electronic adhesives will exceed 8 billion yuan, of which organic silicone accounts for 38.7%. Smart manufacturing upgrades have significantly improved production efficiency. Xin'an's Hangzhou factory has achieved large-scale production of 200,000 tons of liquid glue per year through a fully automated production line, and the yield rate has increased to 98%.

2. Outlook: Four major trends reshape the industrial ecology
High-end wave: Demand for new energy vehicles and AI hardware has exploded, and the amount of silicone rubber used per vehicle has reached 3-5kg. In 2024, global sales of new energy vehicles will exceed 18 million, driving the demand for automotive silicone rubber to grow by 28%. The average annual growth rate of 5G base station sealing materials and chip packaging glue exceeds 30%, and the procurement amount of companies such as Huawei and ZTE has increased by 40% year-on-year.

Green transformation: Bio-based silicone rubber has become the focus of research and development. The production cost of corn starch-based products is 30% lower than that of petroleum-based products, and the tensile strength reaches 12MPa, which is close to the level of traditional products. The policy dividend is accelerating, and the US "Inflation Reduction Act" provides a maximum 30% tax credit for bio-based materials.
Global layout: The infrastructure boom in Southeast Asia and the Middle East has spawned overseas demand, and the export volume of silicone rubber will increase by 24% in 2024. Local enterprises are accelerating the construction of overseas production capacity. Hesheng Silicon Industry has established a high-temperature adhesive base with an annual output of 100,000 tons in Vietnam to avoid the risk of international trade friction.
Intelligent reconstruction: Tesla's Shanghai Super Factory practice shows that the AI process control system has increased the yield rate to 99.3%, and predictive maintenance has extended the advance warning of equipment failure to 72 hours. The industry will evolve to the "digital twin + flexible production" model, and the delivery cycle of customized products will be shortened by 60%.
In the next five years, the silicone rubber industry will continue to evolve around the main line of "high-end, green, intelligent, and globalization". The resonance effect of technological breakthroughs and demand upgrades will drive the industry towards a trillion-level market.
