Engineered for Extreme Heat, Fire, and Structural Performance
Overview
DC600 is a next-generation ceramic fiber-reinforced alumina composite, specifically developed to perform under extreme thermal and mechanical stress. Withstanding continuous use up to 1260°C (2300°F), it offers structural integrity and impact resistance far beyond the limits of conventional plastics or asbestos cement materials. Designed as both a full-size board and for precision-fabricated parts, DC600 is ideal for environments where flame resistance, mechanical durability, and thermal insulation are critical.
Instant Ceramization
Transforms into a rigid, insulating ceramic layer at elevated temperatures - up to 1200°C - ensuring structural protection during fire exposure.
Exceptional Flame Resistance
Maintains shape, strength, and insulation even under direct flame or thermal shock. Rated for fire-critical applications.
Superior Mechanical Performance
High flexural and compressive strength, excellent impact resistance, and non-brittle characteristics-outperforms asbestos cement across all temperature ranges.
Electrical & Thermal Insulation
Reliable dielectric properties both before and after ceramization. Provides dual-phase insulation for high-voltage and sensitive systems.
Eco-Safe & Durable
Halogen-free, non-toxic formulation. Offers long-term waterproofing, anti-aging, and resistance to extreme vibration, seismic activity, and chemical exposure.
Lightweight & Space-Efficient
High-performance protection in an ultra-thin, low-mass design - lighter than ceramics, more compact than mica sheets.
EV Battery Fire Barriers & Thermal Interfaces
Aerospace & Aviation Wiring Protection
Nuclear & High-Voltage Infrastructure
Industrial and Defense-Grade Fire Shields
Ceramic Shield Technology - Actively reinforces its barrier under heat, unlike standard silicone.
High Alumina Content - Provides superior chemical and molten metal resistance (e.g., aluminum contact).
Versatility - Available as large panels or custom-cut components to fit specific design and installation needs.
Certifiable Compliance - Custom formulations can meet UL94 V-0, IEC 60754, and other international safety standards.
