1. Development status: Capacity expansion and demand drive in parallel
The global silicone resin market is experiencing structural growth. In 2024, the global silicone resin market will reach US$20.21 billion, with an estimated compound annual growth rate of 6.8% from 2024 to 2029. As the world's largest consumer, China's market size is expected to exceed 5 billion yuan in 2025, and the annual capacity utilization rate will increase to 83%.

Differentiated competition patterns are presented in the sub-sectors:
Electronic packaging: In 2025, China's electronic potting silicone resin market will reach 18 billion yuan, and new energy vehicles and 5G base station construction will drive demand. Room temperature vulcanized silicone rubber (RTV) accounts for 60% of the market share, heat-cured silicone rubber (HTV) accounts for 30%, and addition-type liquid silicone rubber (LCR) accounts for 10%.
Architectural coatings: With its weather resistance advantage, silicone resin has a penetration rate of over 40% in the field of exterior wall coatings and sealants, with South China and East China accounting for over 65%.
Automobile manufacturing: Each new energy vehicle uses 2-3kg of silicone resin, which is used in battery thermal management, window sealing and other scenarios. In 2025, the sales volume of new energy vehicles in China will account for more than 30%.
Technological breakthroughs accelerate domestic substitution: Domestic companies have mastered the synthesis technology of methyl silicone resin and phenyl silicone resin. Huitian New Materials has a market share of more than 30% in the field of new energy vehicles, and Zhonglai shares have a 25% application coverage of 5G communication equipment.

2. Outlook: Four major trends reshape the industry landscape
High-end breakthrough: Semiconductor packaging and flexible electronics fields have higher requirements for silicone resin. The annual growth rate of biocompatible silicone resin in the medical implant market exceeds 20%, and the tensile strength of nano-modified silicone resin exceeds 15MPa, meeting the extreme environment requirements of aerospace.
Green transformation: Low-VOCs content products have become mainstream. The VOCs emissions of a certain company's environmentally friendly silicone resin are 70% lower than those of traditional products, and have been used in photovoltaic module packaging. Policies force the industry to upgrade, and the elimination rate of enterprises that do not meet environmental protection standards exceeds 30%.
Intelligent upgrade: AI process control increases production yield to 99.5%, and predictive maintenance reduces equipment downtime by 40%. Hesheng Silicon Industry's Xinjiang factory has achieved full process automation, with a single-line production capacity of 100,000 tons/year.
Global layout: The infrastructure boom in Southeast Asia has spawned overseas demand, and domestic companies have accelerated overseas factory construction to avoid trade barriers. In 2025, silicone resin exports will increase by 35% year-on-year, with Vietnam and Indonesia accounting for more than 20% of the market.

In the next five years, the silicone resin industry will evolve around the main line of "localization of high-end materials, popularization of green processes, normalization of intelligent manufacturing, and localization of global supply chains". The market size is expected to exceed 10 billion yuan, becoming an important growth pole in the field of new materials.
