Overview
Calcium Silicate Composite is a high-performance inorganic material primarily composed of calcium silicate hydrate reinforced with fibers or other additives. It is widely recognized for its exceptional thermal insulation and fireproofing capabilities, making it a staple in construction and industrial applications. Developed as an alternative to traditional insulation materials like asbestos, it combines safety with efficiency. Its lightweight nature and ease of installation further enhance its appeal in modern building projects, particularly in energy-efficient and fire-resistant designs.
Physical and Chemical Properties
The composite exhibits low thermal conductivity (typically 0.05–0.10 W/m·K), enabling effective heat retention or blockage. Its porous structure contributes to both insulation and soundproofing qualities. Chemically, it is stable under most environmental conditions, resisting degradation from moisture, mold, and UV exposure. The material is non-combustible, withstanding temperatures up to 1,000°C, which makes it ideal for fireproof partitions and industrial furnace linings.
Main Applications
In construction, it is used for wall and ceiling insulation, fireproof doors, and HVAC system enclosures. Its durability and resistance to high temperatures also suit industrial settings, such as piping insulation in refineries. The material is equally valuable in shipbuilding and aerospace for its lightweight and fire-resistant properties. Recent innovations include its use in prefabricated modular buildings, where speed of assembly and safety are prioritized.
Safety and Storage
While non-toxic, cutting or sanding the composite can generate dust, requiring proper ventilation and PPE like masks and goggles. It is chemically inert and poses no significant environmental hazards. Storage should prioritize dryness to prevent moisture absorption, which could affect its insulation performance. Pallets or shelves are recommended to avoid ground contact, especially in humid climates.
B2B Procurement Guide
When sourcing Calcium Silicate Composite, prioritize suppliers with ISO or ASTM certifications to ensure quality consistency. Key specifications to verify include thermal conductivity ratings (λ-value), fire resistance class (e.g., A1 non-combustible), and flexural strength. Bulk purchases often qualify for discounts, but confirm lead times and minimum order quantities. For specialized applications (e.g., high-humidity environments), request customized formulations with enhanced water repellency.
