LTF-250

SECTION 2: Hazards identification

Emergency Overview Caution Color blue, tint Form: solid Plastic film Odor: Odorless. Melted product is combustible and produces intense heat and dense smoke during burning. Toxic gases/fumes are given off during burning or thermal decomposition and may cause allergic skin and respiratory reaction. Contact with hot material will cause thermal burns.

Principle Routes of Exposure

Inhalation, Skin Contact, Eye Contact

Medical Conditions Generally Aggravated by Exposure

Respiratory disorders HUMAN EFFECTS AND SYMPTONS OF OVEREXPOSURE Inhalation Acute Inhalation Thermoplastic Polyurethane (TPU) film is generally non-hazardous under ambient conditions as well as under recommended processing temperatures and conditions when following good manufacturing practices. However, as is common for all Diphenylmethane Diisocyanate (MDI)-based thermoplastic urethanes, if the material is subjected to temperatures above its decomposition temperature (482°F / 250°C in the case of this product), MDI may be liberated. The following effects reflect the potential

Health hazards

associated with overexposure to MDI. Diisocyanate vapors or mist at concentrations above the TLV or PEL can irritate (burning sensation) the mucous membranes in the respiratory tract (nose, throat, lungs) causing runny nose, sore throat, coughing, chest discomfort, shortness of breath and reduced lung function (breathing obstruction). Persons with a preexisting, nonspecific bronchial hyperreactivity can respond to concentrations below the TLV or PEL with similar symptoms as well as asthma attack or asthma-like symptoms. Exposure well above the TLV or PEL may lead to bronchitis, cont’d bronchial spasm and pulmonary edema (fluid in lungs). Chemical or hypersensitivity pneumonitis, with flu-like symptoms (e.g., fever, chills), has also been reported. These symptoms can be delayed up to several hours after exposure. These effects are usually reversible. Chronic Inhalation In the event of material decomposition due to exceeding the decomposition temperature of this product, release of MDI may occur. As a result of previous repeated overexposures or a single large dose, certain individuals may develop sensitization to diisocyanates (asthma or asthma-like symptoms) that may cause them to react to a later exposure to diisocyanates at levels well below the TLV or PEL. These symptoms, which can include chest tightness, wheezing, cough, shortness of breath or asthmatic attack, could be immediate or delayed up to several hours after exposure. Extreme asthmatic reactions can be life threatening. 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. This increased lung sensitivity can persist for weeks and in severe cases for several years. Sensitization can be permanent. Chronic overexposure to diisocyanates has also been reported to cause lung damage (including fibrosis, decrease in lung function) that may be permanent. Skin Acute Skin Contact with heated material can cause thermal burns. Eye Vapors released from thermal decomposition may cause irritation with symptoms of burning and tearing.
