Airfoam Flotation Billets are the most cost effective buoyancy material in the market providing superior performance for virtually any commercial or residential floatation application. Made from expanded polystyrene (EPS) and 98% air, they are extremely lightweight & buoyant, floating up to 62 lbs/ft³. With outstanding stability, EPS Floatation components resist decomposition, moisture, mold, fungi and many adverse conditions, including freeze-thaw cycles, while providing excellent compressive strength over very long service periods.
Airfoam Flotation Billets can be factory-shaped to your specific needs for fast installation into your flotation assembly system. Available with sturdy coatings for long term resistance to water penetration, punctures, and UV-rays, Airfoam EPS Flotation solutions can be used in fresh and salt water.
Boat docks, marinas, boathouses, swim rafts, piers, floating homes, even golf tees and floating heliport pads
Polyurethane elastomeric coating is very sturdy, high performance protection for the EPS flotation core, providing excellent chemical and abrasion resistance. It is an inexpensive way to safeguard your floatation investment especially in areas where petroleum-based products can be present.
Expanded Polystyrene (EPS) is a resilient, closed cell, rigid foam material that uses air as main ingredient.
Load Distribution: Poisson's ratio ≈0.12 within the elastic range; Coefficient of Friction μ: 0.5-0.7 along clean faces
Buoyancy-Force: up to 989 kg/m³ [62 lbs/ft³]. Where needed, protect against uplift/flotation.
Expanded Polystyrene (EPS) resists mold & fungi growth per ASTM C1338 and has no nutritional value for insects. To protect against insects/termites and water-vapor place adequate physical barriers such as membranes around below-grade EPS. Where needed, use adequate drainage to limit water absorption; Capillarity: None
Max. Service Temperature: Long-Term Exposure 75°C [167°F], Intermittent Exposure 80°C [176°F]; Thermal expansion coefficient:
Solubility: Insoluble in water and in general chemically inert. EPS dissolves in hydrocarbons (e.g. fuels, oils, tar), organic solvents (e.g. acetone/ketones, benzene, paint thinner), ethers, esters, aldehydes and amines. UV-light surface degradation: white EPS can be exposed to direct sunlight for a few weeks. Prolonged exposure to ultraviolet light creates a yellow dust on the surface of EPS which has negligible impact on the products' properties but may require removal before adhering other materials such as coatings or self-adhesive membranes.
Surface Burning Characteristics Canada CAN/ULC-S102.2: Flame-Spread Rating ≤290, Smoke Developed Classification over 500. USA ASTM E84 (UL 723): Flame Spread Index ≤25, Smoke-Developed Index ≤450 up to 6" thick
Limiting Oxygen Index: min. 24% per ASTM D2863. Airfoam's EPS for construction use contains a polymeric (non-HBCD) fire retardant modifier.
CAUTION: EPS products are combustible and must not be exposed to excessive heat, sparks, open flames, or any other sources of ignition. If stored/used in closed containers, confined, or low-lying areas, ensure adequate ventilation to prevent accumulation of flammable pentane vapours. Prevent inhalation of smoke, fumes or dust from burning or fabrication activities. GHS Classification: Non-Hazardous, see SDS
