Size: Typically available in rolls or sheets, ranging from 1m x 1m to 2m x 4m, with thicknesses from 10mm to 100mm.
Grade: Classified as A0, A15, A30, A60 for fire resistance, with additional grades for acoustic and thermal performance.
Viscosity: N/A (solid materials); adhesive variants may have viscosities ranging from 5,000 to 50,000 cP.
Buoyancy: Closed-cell foam variants offer buoyancy with densities between 30kg/m³ to 200kg/m³.
Material: Common materials include mineral wool, fiberglass, polyurethane foam, PVC foam, and elastomeric rubber.
Fire Resistance: Compliant with IMO FTP Code, SOLAS, and ASTM E84 standards.
Acoustic Performance: Sound Transmission Class (STC) ratings of 25-50 dB, Noise Reduction Coefficient (NRC) up to 0.95.
Thermal Conductivity: R-values range from 0.5 to 4.0 (m²·K)/W.
Density: Varies from 30kg/m³ (lightweight foam) to 200kg/m³ (high-density composites).
Water Resistance: Hydrophobic materials with low water absorption (<1% by volume).
