DC600 Boards are ceramic fiber reinforced structural alumina composite material with useful properties to 1260°C (2300°F). They have flexural and compressive strength in the range of high temperature plastic but retain strength and utility to levels far exceeding maximum use temperatures of plastics. Mechanical properties of Type DC600 sheets exceed those of asbestos cement materials over all temperature ranges. Their high Alumina content make them resistant to many environments including molten aluminum. They are not brittle and have high impact resistance. Type DC600 is useful both as a full size panel and as a source for precision cut fabricated components.
Advanced Ceramizing Silicone Material - Ultimate Fire & Thermal Protection
Instant Ceramization - Forms a rigid, insulating ceramic layer at high temperatures (up to 1200ºC)
Extreme Flame Resistance - Withstands direct fire exposure while maintaining structural integrity
Dual-Phase Insulation - Provides reliable electrical insulation before and after ceramization
Eco-Safe Protection - Halogen-free, non-toxic formulation with superior flame retardancy
Unmatched Durability - Waterproof, anti-aging, and resistant to seismic/temperature shocks (-60ºC to +300ºC)
Space-Saving Design - Ultra-thin, lightweight profile for compact applications
Ideal for: Electric vehicle batteries, aerospace wiring, nuclear plants, and high-voltage infrastructure where fire safety and thermal management are critical.
Engineered to protect where conventional materials fail - transforming heat into an insulating barrier.
Need custom specifications or compliance details? (UL94 V-0, IEC 60754, etc.)
Why It's Unique:
→ Ceramic Shield Technology: Unlike standard silicones, it actively reinforces protection under fire
→ Weight-to-Performance Ratio: Thinner than mica, lighter than ceramic
