SECTION 1 -- IDENTITY
NAME: Flexible urethane foam
CHEMICAL TYPE: Polyether-based urethane polymer
TRADENAMES & SYNONYMS: Flexible polyurethane foam, pure foam, flame retardant foam,
high comfort foam, HR foam, antistatic foam & others.
--------------------------------------------------------------------------------------------------------------------------------------------------------
SECTION 2 -- HAZARDOUS INGREDIENTS
The material is not made from chemical components that are known to represent possible
carcinogenic, mutasinic or other chronic hazards. However, TDI mixed with corn oil administered to lab animals has been shown to be carcinogenic.
--------------------------------------------------------------------------------------------------------------------------------------------------------
SECTION 3 -- PHYSICAL & CHEMICAL CHARACTERISTICS
Since urethane foam is a solid, physical characteristics such as boiling point, vapor pressure,
vapor density, percent violates, evaporation rate, etc. are not applicable.
DENSITY: 0.9 - 4.0 lbs. per cu. ft.
IGNITION POINT: 600 - 650 degrees F
AUTOIGNITION POINT: 750 - 800 degrees F
APPEARANCE: Can come in any color. Looks like a cellular material similar to foam rubber.
--------------------------------------------------------------------------------------------------------------------------------------------------------
SECTION 4 -- FIRE & EXPLOSION HAZARD DATA
OSHA CLASSIFICATION: Combustible solid
NFPA SPRINKLER CLASSIFICATION: Upholstery with plastic foams. Extra hazard.
EXTINGUISHING MEDIA: Water spray, carbon dioxide, dry powder
FIRE FIGHTING PROTECTION: Use NIOSH-approved self-contained breathing apparatus &
protective clothing including boots.
UNUSUAL FIRE HAZARDS: Once ignited, can produce rapid flame spread, intense heat,
dense smoke and toxic gases. Can turn into burning liquid which can drip and flow.
----------------------------------------------------------------------------------------------------------------------------------------------
----------
SECTION 5 -- PHYSICAL HAZARDS
REACTIVITY: Stable. Hazardous polymerization will not occur.
CONDITIONS TO AVOID: Strong acids and alkalis will deteriorate foam properties.
INCOMPATIBILITY: Unknown
HAZARDOUS DECOMPOSITION PRODUCTS: Combustion, hot wire cutting, heat sealing, hot
stamping & flame laminating operations of foam may produce carbon monoxide, oxides of
nitrogen and traces of isocyanates & hydrogen cyanide.
--------------------------------------------------------------------------------------------------------------------------------------------------------
SECTION 6 -- HEALTH HAZARDS
THRESHOLD LIMIT VALUE: None established
OSHA PERMISSIBLE EXPOSURE: None established
ACUTE ORAL LD 50: Greater than 5000 mg./kg. (rat)
ACUTE DERMAL LD 50 LIMIT: No available data
PRIMARY SKIN IRRITANT: Not known to be irritant
EYE IRRITATION: Dust can cause irritation
PRIMARY ROUTE OF ENTRY: Foam dust -- inhalation
INHALATION: Animal studies indicate that chronic overexposure to dusts may cause inflammation of the lungs, fibrosis & airway obstruction.
CHEMICAL LISTED AS CARCINOGEN OR POTENTIAL CARGINOGEN
National Toxicology Program: No
I.A.R.C. Monographs: No
OSHA: No
EMERGENCY FIRST AID PROCEDURES
SKIN: Does not apply
INGESTION: Does not apply
EYES: Flush thoroughly with water
INHALATION (OF DUST): Call physician if coughing, discomfort or air passage obstruction
occurs.
--------------------------------------------------------------------------------------------------------------------------------------------------------
SECTION 7 -- SPECIAL PROTECTION INFORMATION
VENTILATION: Use adequate mechanical ventilation when hot wire cutting, heat sealing, hot
stamping & flame laminating flexible urethane foam. Also use ventilation in operations that
will generate large quantities of foam dust such as in continuous sawing, fabrication or buffing
operations.
PROTECTIVE EQUIPMENT: Unless exposure to foam dust is anticipated, goggles, gloves &
dust masks are not required.
