Industrial Calcium Silicate Boards & Insulation

Core Value Proposition for Industrial Applications

• Unmatched Fire Integrity: Provides passive fire protection, maintaining critical insulation and structural barriers during fire events.

• High-Temperature Stability: Engineered to withstand continuous high-temperature service with minimal linear shrinkage.

• Mechanical Robustness: Offers high compressive strength and durability in challenging plant environments.

• Long-Term Reliability: Resistant to moisture, corrosion, and thermal cycling, ensuring prolonged service life and reduced maintenance costs.

Key Performance Characteristics

1. Thermal Performance & Temperature Resistance

• Service Temperature Range:

  • Standard Grade: Up to 650°C (1200°F) continuous service

  • High-Temperature Grade: Up to 1100°C (2012°F) continuous service

• Low Thermal Conductivity: Typically 0.05 - 0.07 W/m·K at 100°C, ensuring high energy efficiency.

• Minimal Linear Shrinkage: <2% at maximum service temperature, preserving system integrity and preventing gaps.

2. Fire Safety & Protection

• Non-Combustible (A1 Class): Will not ignite, fuel a fire, or emit significant smoke.

• Fire Rating: Can provide up to 4 hours of fire resistance for structural elements (ratings vary by system design).

• Integrity Protection: Maintains barrier integrity to prevent spread of fire and hot gases.

3. Mechanical & Physical Properties

• High Compressive Strength: Ranges from 0.5 MPa to >8 MPa, depending on density, allowing use in load-bearing applications.

• Density Range: Industrial grades typically from 220 kg/m³ to 1000 kg/m³.

• Dimensional Stability: Low coefficient of thermal expansion and excellent resistance to warping or sagging.

4. Chemical & Environmental Resistance

• Moisture Resistant: Low water absorption; treated grades offer enhanced hydrophobic properties.

• Chemical Inertness: Resistant to most oils, solvents, and weak acids/alkalis. Chemically stable in most industrial atmospheres.

• Corrosion Inhibition: Non-corrosive to pipes and vessels; chloride content is typically controlled to prevent stress corrosion cracking (SCC) on stainless steel.
