containing Methylene bisphenyl

isocyanate CAS 000101-68-8

Polyurethane prepolymer of MDI

(CAS 068092-58-0) 20-25 Not listed

Bis (2-ethylhexyl) phthalate

(CAS 117-81-7) 56 5 mg/m3




APPEARANCE & ODOR: Pale yellow odorless liquid


SPECIFIC GRAVITY: 1.0698 at 20oC

VAPOR PRESSURE: <0.0001 mm Hg at 20oC





FLASH POINT: 420oF Cleveland Open Cup

EXTINGUISHING MEDIA: Dry chemical, carbon dioxide, foam, halogenated agents. If water is used, use very large quantities. The reaction between water and hot isocyanate may be vigorous.

SPECIAL FIRE FIGHTING PROCEDURES: Full emergency equipment with self-contained breathing apparatus and full protective clothing should be worn by firefighters.

UNUSUAL FIRE OR EXPLOSION HAZARDS: Water contamination will produce carbon dioxide. Do not reseal contaminated containers as pressure buildup may rupture them.




STABILITY: Stable under normal conditions

INCOMPATIBILITY (MATERIALS TO AVOID): This product will react with any materials containing active hydrogens, such as water, alcohol, ammonia, alkalies and acids. The reaction with water is very slow under 50oC, but is accelerated at higher temperatures and in the presence of alkalies, tertiary amines, and metal compounds. Some reactions can be violent.

HAZARDOUS POLYMERIZATION: May occur. High temperatures in the presence of alkalies, tertiary amines, and metal compounds will accelerate polymerization. Possible evolution of carbon dioxide gas may rupture closed containers.

HAZARDOUS DECOMPOSITION PRODUCTS: Combustion products: carbon monoxide, carbon dioxide, nitrogen oxides, ammonia and trace amounts of hydrogen cyanide.




GENERAL: No toxicity information is available on this specific preparation; this health hazard assessment is based on information that is available on the properties of its components.


INHALATION: Although MDI is low in volatility, an inhalation hazard can exist from MDI aerosols or vapors formed during heating, foaming or spraying.

Acute Exposure. Vapors and aerosols can irritate eyes, nose and respiratory passages. Severe overexposure may lead to pulmonary edema. MDI can induce respiratory sensitization with asthma-like symptoms. Symptoms include chronic cough, tightness of chest with difficulty in breathing. These symptoms may be immediate or delayed up to several hours after exposure.

Chronic Exposure. As a result of previous repeated overexposures or a large single overdose, certain individuals develop isocyanate sensitization which will cause them to react to a later exposure to isocyanate at levels well below the TLV. Similar to many non-specific asthmatic responses, there are reports that once sensitized an individual can experience these symptoms upon exposure to dust, cold air or other irritants. Overexposure to isocyanates has also been reported to cause lung damage which may be permanent. Sensitization can be either temporary or permanent.


Acute Exposure. Harmful if absorbed through skin.

Chronic Exposure. Isocyanate skin sensitization and irritation are likely to develop after repeated and/or repeated contact with human skin. Overexposure to Bis(2-ethylhexyl)phthalate has apparently been found to cause testis damage in laboratory animals.


Acute Exposure. This material will probably irritate human eyes following contact.

Chronic Exposure. None found.


Acute Exposure. The acute oral LD50 in rat is probably above 5,000 mg/kg for MDI. Relative to other materials, MDI is classified as 'practically nontoxic' by ingestion. Irritation of the mouth, pharynx, esophagus and stomach can develop following ingestion.

Chronic Exposure. None found

CARCINOGENICITY: Both the National Toxicology Program and International Agency for Research on Cancer (IARC) have determined that there is sufficient evidence for the carcinogenicity of Bis(2-ethylhexyl)phthalate (BEHP) in experimental animals. When administered in the diet produced an increased incidence of hepatocellular carcinomas in female rats and male and female mice, and an increased incidence of hepatocellular carcinomas or neoplastic nodules in male rats. It has also been shown to cause fetotoxicity and teratogenicity in pregnant female rodents. However, no relationship between BEHP exposure and cancer in humans has been observed during more than 35 years of worldwide use.


Skin: Wash material off skin with plenty of soap and water. For severe exposures, get under safety shower after removing clothing, then get medical attention. For lesser exposure, seek medical attention if irritation develops or persists after the area is washed. Do not reuse clothing until cleaned. Destroy contaminated shoes.

Eyes: Flush with copious amounts of water for at least 15 minutes holding eyelids open. Get medical attention immediately.

Ingestion: Give 1 to 2 cups of water to drink. Induce vomiting. Do not give anything by mouth to an unconscious person. Get medical attention.

Inhalation: Move to area free of risk to further exposure. Administer oxygen or artificial respiration as needed. Get medical attention.




STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED: Evacuate and ventilate spill area; dike spill to prevent entry into water system; wear full protective equipment during cleanup.

Clean Water Act and Superfund reportable quantity (RQ) for BEHP: 100 lbs

Major Spill: If temporary control of isocyanate vapor is required, a blanket of protein foam may be placed over the spill. Large quantities may be pumped into closed, but not sealed container for disposal.

Minor Spill: Absorb material with sawdust or other absorbent, shovel into suitable unsealed containers, transport to well-ventilated area (outside). Prepare a decontamination solution of 0.2-0.5% liquid detergent and 3-8% concentrated ammonium hydroxide in water (5-10% sodium carbonate may be substituted for ammonium hydroxide). Follow precautions on supplier's material safety data sheets. All operations should be performed by trained personnel familiar with the hazards of chemicals used. Treat the spill area with the decontamination solution, using 10 parts solution to each part of the spill, and allow it to react for at least 10 minutes. Carbon dioxide will be evolved, leaving insoluble polyureas. Wash residue to a sewer serviced by a wastewater treatment facility.

Clean-up: Decontaminate floor with decontaminating solution, letting stand for at least 15 minutes.

WASTE DISPOSAL METHOD: Slowly stir the isocyanate waste into the decontamination solution described above using 10 parts of solution for each part of isocyanate. Let stand for 48 hours, allowing the evolved carbon dioxide to vent away. Neutralize the waste. Dispose of according to federal, state and local laws. Drums must be decontaminated in properly ventilated areas by personnel protected from the inhalation of isocyanate vapors. Spray or pour 5-15 liters of decontaminating solution into the drum, making sure the walls are well rinsed. Leave the drum soaking unsealed for 48 hours. Pour out the decontaminating solution and triple rinse the container. Puncture or otherwise destroy the rinsed container before disposal.




TLV OR SUGGESTED CONTROL VALUE: No ACGIH TLV or OSHA PEL is assigned to this mixture. Control of exposure to below the TLV for the ingredients (see II) may not be sufficient. Minimize exposure in accordance with good hygiene practice. ACGIH TLV for MDI is 0.005 ppm 8 hour TWA. The OSHA PEL for MDI is 0.02 ppm, ceiling. NIOSH recommends 0.005 ppm TWA and 0.02 ppm STEL. These control limits do not apply to previously sensitized individuals or those with existing respiratory disease. ACGIH TLV for Bis(2-ethylhexyl)phthalate is 5 mg/m3 TWA, 10 mg/m3 STEL. The OSHA PEL is 5 mg/m3

EYE PROTECTION: Liquid chemical goggles or full face shield.

SKIN PROTECTION: Gloves determined to be impervious under conditions of use. Depending on conditions of use, additional protection may be required such as apron, arm covers, or full body suit. Tests indicate that clothing constructed of butyl rubber, nitrile rubber and some neoprene garments have excellent resistance to permeation by MDI. Clothing constructed of polyethylene, latex rubber, PVC or polylaminated Tyrek showed little resistance to permeation by MDI.

RESPIRATORY PROTECTION: Because of low vapor pressure, ventilation is usually sufficient to keep vapors below the TLV at room temperatures. Exceptions are when the material is heated, sprayed or used in a poorly ventilated area. In such cases or whenever concentrations exceed the TLV, use MSHA/NIOSH approved positive pressure supplied air respirator with a full facepiece or an air supplied hood. Air purifying (cartridge type) respirators are not approved for protection against isocyanates.

VENTILATION: Local exhaust should be used to keep airborne concentrations below the TLV whenever MDI is processed, heated or sprayed.

OTHER PROTECTIVE EQUIPMENT: Eyewash station and safety shower in work area.




Store in tightly sealed containers to protect from atmospheric moisture. Temperatures below 55oF will cause a separation of the solution that is reversible by heating to about 75oF and tumbling or rolling container to mix. Material quality will deteriorate if stored at temperatures over 100oF (3-6 months). Educate and train employees in safe use of product.
