Fluorosilicone in AI Data Centers — Dielectric Coolants Become the New Growth Frontier

Emerging Application: Beyond traditional automotive and aerospace markets, fluorosilicone fluids are finding an unexpected growth driver: artificial intelligence data centers. As AI server power densities skyrocket, conventional air cooling can no longer meet thermal management requirements, creating explosive demand for single-phase immersion cooling solutions.

Market Context: In the first quarter of 2026, Sichuan Chenguang Boda New Materials Co., Ltd. reported that its “Ice Core“ series perfluoropolyether cooling fluids—which share fundamental technology with high-performance fluorosilicone fluids—achieved year-over-year sales growth exceeding 60%, driven by demand from internet data center operators and AI infrastructure providers.

Technical Requirements: Immersion cooling fluids for AI servers must meet stringent specifications:

• Electrical insulation (dielectric strength >30 kV)

• Non-flammability (critical for fire safety in high-density server environments)

• Chemical inertness (no corrosion of server components including solder joints, capacitors, and connectors)

• Excellent dielectric properties (stable performance under continuous operation)

Performance Benefits: Systems using fluorosilicone-based immersion cooling achieve:

• 30% to 50% energy savings compared to air-cooled systems

• Reduced cooling infrastructure footprint (no chillers, CRAC units, or raised floors required)

• Lower power usage effectiveness (PUE) — many installations achieve PUE below 1.1

Market Significance: This application represents a fundamental expansion of the fluorosilicone addressable market. While traditional automotive and aerospace applications remain volume drivers, data center cooling offers higher growth rates and premium pricing. Industry estimates suggest the immersion cooling fluid market could reach USD 1-2 billion by 2030, with fluorosilicone and perfluoropolyether fluids capturing significant share.

Competitive Landscape: Major fluorosilicone producers including Dow, Shin-Etsu, and 3M (prior to its PFAS exit) have developed immersion cooling portfolios. Chinese suppliers including Chenguang Boda, Wynca, and others are rapidly scaling production capacity to capture domestic and export opportunities as AI infrastructure investment accelerates globally.
