Additional Properties of EPS
Expanded Polystyrene (EPS) has no nutritional value for organisms and resists mold & fungi growth per ASTM C1338. To protect against animals place adequate physical barriers such as bug-screens or membranes around EPS.
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. Capillarity: None
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.
Surface Burning Characteristics Canada CAN/ULC-S102.2: Flame-Spread Rating ≤295, Smoke Developed Classification over 500. USA Class A (NFPA 101), ASTM E84 (UL 723)ª: 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 applications 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. A protective barrier or thermal barrier is required as specified in the appropriate building code. 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
ª Ceiling measurement only, conducted through determination of flame spread index and smoke-developed index with the removal of any contribution of molten materials ignited on the floor of the Steiner tunnel.
Material Properties of Korolite® Graphite-enhanced EPS (GPS) Insulation Types
1 The test methods used to determine the material properties provide a means of comparing different cellular plastic thermal insulations. They are intended for use in specifications, product evaluations and quality control, but they are not intended to predict end-use product performance. 2 The elastic limit is between 1% and 2% strain. Compressive resistances at 10% strain are provided for applications where the intended end-use can tolerate plastic (permanent) deformation under load. 3 R means resistance to heat flow. The higher the R-value, the greater the insulating power. 4 Values are for 1 inch or 25mm thick samples with natural skins intact. Better values will result for thicker materials. 5 The lab-test methods for water absorption use complete submersion under a head of water for 24 or 96 hours, so the values are applicable to specific design requirements only when the end-use conditions are similar to test method requirements. 6 not part of all the industry consensus standards (ASTM C578, CAN/ULC-S701) and provided AS-IS solely for informational purposes. 7 Minimum Density only applicable to USA-bound products per ASTM C578 (not Canada-bound products per CAN/ULC-S701.1).
Additional Properties of GPS
Graphite-enhanced expanded polystyrene (GPS) has no nutritional value for organisms and resists mold & fungi growth per ASTM C1338. To protect against animals place adequate physical barriers such as bug-screens or membranes around GPS.
Deformation due to Thermal Radiation: unprotected, gray GPS will deform when exposed to direct or reflected sunlight or other radiant heat sources. Keep GPS covered using opaque tarp, reflective covers or suitable indoor storage until finishes are installed.

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 and Fire Safety Bulletin
