Millegap vermiculite insulation: 48h fast delivery

Natural Thermal Resistance Mechanisms in Vermiculite

Vermiculite insulation achieves exceptional thermal resistance through its layered mineral structure that traps air pockets, slowing conductive heat transfer. With a thermal conductivity range of 0.10-0.20 W/mK (National Institute of Standards and Technology 2023), it outperforms conventional materials like fiberglass in high-temperature stability due to:

• Interlayer spacing: 6-9 Å gaps between silicate layers
• Hydrated mineral composition: Chemically bound water molecules
• Platelet orientation: Randomly aligned layers disrupting heat flow

Low Thermal Conductivity Under Extreme Conditions

Vermiculite maintains thermal conductivity below 0.25 W/mK at 1000°C—32% lower than refractory ceramic fibers (International Journal of Thermal Sciences 2022). Its consistent performance across temperature ranges makes it ideal for foundries and power plants:

Lightweight Yet Durable Structure for Efficient Insulation

Vermiculite boards combine a bulk density of 550-750 kg/m³ with compressive strengths up to 2.5 MPa (ASTM C165-23), offering:

• 60% weight reduction versus firebricks
• Easy cutting with standard tools
• ±0.3% shrinkage after 100 freeze-thaw cycles
  Field tests show 98% insulation value retention after 15 years in industrial use.

Superior Fireproof Performance Up to 1200°C: Safety and Compliance

Incombustible Material Meeting International Fire Safety Standards

Vermiculite achieves Class A fire ratings (ASTM E84) through inherent incombustibility, maintaining <0.8% smoke density under extreme heat (BS 476-6). Its stable char layer formation prevents oxygen diffusion, outperforming cellulose-based insulants.

Thermal Stability and Integrity in Prolonged High-Temperature Exposure

Structural tests (ISO 834) show vermiculite retains 98% compressive strength after 4 hours at 1100°C—far exceeding ceramic fiber's 15-20% degradation. In glass manufacturing, vermiculite-lined furnaces show <1mm thermal creep after 2,000 cycles.
