Airfoam Floatation Billets are the most cost effective bouyancy 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 56 lbs/ft³ or more. With outstanding stability, EPS Flotation 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
Poly-Urethane 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 further protect your floatation investment especially in areas where petroleum-based products can be present.
Expanded Polystyrene (EPS) is a resilient, closed cell, rigid foam plastic material using air as main ingredient.
Expanded polystyrene (EPS) is resistant to mold & fungi per ASTM C1338 and has no nutritional value for insects. To protect against termites place adequate physical barriers such as membranes around below-grade EPS.
Limiting Oxygen Index: min. 24% per ASTM D2863. Airfoam's EPS for construction applications contains a polymeric (non-HBCD) flame-retardant modifier.
Max. service temperature: Long-Term Exposure 75°C [167°F]; Intermittent Exposure 80°C [176°F]
Thermal expansion coefficient: 5-7 •
Capillarity: None; Buoyancy-Force: min. 900 kg/m³ [56 lbs/ft³]
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.
Load Distribution: Poisson's ratio ≈0.12 within the elastic range; Coefficient of Friction: ≈0.5 along molded, clean faces
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 products, which has negligible impact on the products' properties but may require removal before adhering other materials such as stucco or self-adhesive membranes.
GHS Classification: Non-Hazardous, see SDS
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.
