MATERIAL SAFETY DATA SHEET Issue No: 6 Effective Date; October 1994 Serial No.: RAY/3122 PRODUCT IDENTIFICATION THIS MSDS IS FURNISHED FOR A GROUP OF PRODUCTS WHICH HAVE SIMILAR PROPERTIES DURING NORMAL CONDITIONS OF USE, BUT WHICH MAY EMIT DISSIMILAR THERMAL DEGRADATION BYPRODUCTS IF OVERHEATED. FOR MORE SPECIFIC INFORMATION, PLEASE CALL (415) 361-4907. Product Name: Thermofit Heat-Shrinkable Polymeric Products (excluding Solder Sleeves see separate MSDS) CAS #: Not applicable mixture. Chemical Name: Not applicable, mixture Manufacturer: Raychem Corporation 300 Constitution Drive Menlo Park, CA 94025 DOT Proper Shipping Name: Not regulated. DOT Identification No. Not regulated DOT Hazard Classification; Not regulated TSCA Inventory Status: Exempt FOR CHEMICAL EMERGENCY, SPILL, LEAK, FIRE, EXPOSURE or ACCIDENT Call CHEMTREC - Day or Night - 1-800-424-9300 Toll free in the continental U.S. Hawaii, Puerto Rico, Canada, Alaska or Virgin Island. For calls originating elsewhere: (202) 483-7616 (collect calls accepted) For non-emergency health and safety information, call: (415) 361-4907 HAZARDOUS INGREDIENTS Heat-Shrinkable Polymeric Products are not hazardous during proper installation, but may emit hazardous thermal decomposition and combustion byproducts if overheated to degradation. See "Thermal Degradation and Combustion Byproduct" section of this MSDS for more specific information. Base polymer materials include polyethylene and olefin copolymers, fluoropolymers, chloropolymers, polyamides, polyesters, and silicones. Heat-shrinkable products may be coated with or used in conjunction with adhesives/mastics which are based on olefin copolymers or polyamides. PRODUCT APPLICATIONS Typical uses of heat-shrinkable polymeric products include primary electrical insulation, EMI/RFI shielding, cable jacketing and repair, strain relief, component encapsulation, waterproofing, packaging, environmental/mechanical protection, and cable joining, splicing, and termination in commercial and military/aerospace electronic applications. PHYSICAL PROPERTIES Appearance and Odor: Plastic tubing and molded parts in a variety of shapes, sizes and colors. No odor. Boiling Point: Not applicable Vapor Pressure (mm Hg @ 20? C): Not applicable Volatility (% by Volume): Not applicable Vapor Density: Not applicable Specific Gravity (Water =1): Not applicable Evaporation Rate: Not applicable Flash Point (?F) / Method: Not applicable Solubility in Water (%): Insoluble Flammable Limits in Air (volume %): Lower Not applicable Upper Not applicable HEALTH HAZARD INFORMATION Exposure Limits: There are no established exposure limits for polymer mixtures. Health Effects/Symptoms of Exposure: Proper installation of this product creates no known acute or chronic health hazards. Acute (Short-Term Exposure): Eye Contact: Contact with molten material may cause thermal burns. Skin Contact: This product is not expected to be a skin irritant. Contact with the molten material may cause thermal burns. No harmful effects are expected from skin absorption of this product. Ingestion (Swallowing): Ingestion of this product is highly unlikely. There is insufficient information available on this material to predict the effects from ingestion. Inhalation (Breathing): In common with most organic materials, thermal degradation and combustion byproducts may be toxic and should not be inhaled. (See Comments below and the Thermal Degradation and Combustion Byproducts Section for more specific information). Chronic (Long-Term Exposure): None of the ingredients to which users may be exposed and which are present at equal to or greater than 0.1% of the product, are listed by OSHA, NTP, or IARC as suspect carcinogens. Comments: Overheating the product to charring or burning may produce vapors that may cause eye, skin, nose and throat irritation. Persons with pre-existing eye, skin, or respiratory disorders (e.g. asthma conditions) may be more susceptible to the effects of these vapors. STORAGE, HANDLING, AND PREVENTATIVE MEASURES Stability at room temperature: This product is stable under normal conditions. Conditions to Avoid: Avoid overheating of product. Incompatibilities (Materials to Avoid): None known. Hazardous Polymerization: Will not occur. No known polymerization conditions to avoid. Thermal Degradation and Combustion Byproducts: In common with most organic materials, degradation and combustion byproducts may be toxic and should not be inhaled. Thermal degradation is not significant at temperatures achieved during proper installation, as directed by product installation guides. At temperatures higher than those recommended for proper installation, most significantly if the product burns, the thermal degradation and combustion byproducts will depend on the base polymer used, and may include, but are not limited to, carbon monoxide, carbon dioxide, aldehydes, acetic acid, low molecular weight hydrocarbons, silicon dioxide, hydrogen chloride, hydrogen fluoride, hydrogen bromide, fluoro-olefins, and oxides of nitrogen, phosphorus, and sulfur. Handling: Avoid any vapors given off if the product is heated to decomposition, as shown by a darkening and browning of the sleeve. Avoid contact with molten material. Heat-resistant gloves are required if hot products are handled after installation. Do not consume food, beverages or tobacco in the immediate work area. Wash hands before eating, drinking or smoking. Other Precautions: Avoid heating products beyond temperatures required for normal installation. See installation instructions for proper installation procedures. If product chars or burns, immediately stop heating. Avoid inhaling any fumes which may be given off under such circumstances. Allow any vapors to disperse and ventilate before continuing work in the area. Ventilation: In accordance with good industrial hygiene practice, ensure adequate ventilation during installation. Respiratory Protection: If installation occurs in a confined, unventilated area, NIOSH/MSHA-approved respirators are recommended. Protective Clothing: OSHA, ANSI., or NIOSH guidelines should be followed. If there is a danger of molten material contacting the skin or eyes, use eye/face protection and heat resistant gloves. If it is necessary to handle grossly overheated or fire-damaged products, wear natural rubber gloves to prevent possible contact with potentially corrosive inorganic acid residues. Transportation: These products are non-hazardous under Department of Transportation Regulations 49, CFR Section 171,8, IATA, IMO, and AFR 71-4. Because there are no applicable shipping regulations for these products, labels are not required on the outside shipping container for these products and all products may be shipped through the U.S. Postal Services. Disposal: Dispose in accordance with all local, state and federal regulations. If there are local regulations covering the controlled incineration of halogenated materials, then all halogen-containing products will be subject to such regulations. Refer to the product literature for identification of halogen-containing products. Installation: Follow appropriate Raychem installation instructions and application guides to ensure that installation is performed properly. Ensure that any local requirements/ legislation concerning the use of hand-held electrical equipment are observed. When using IR (infrared) heating devices, observe specific instructions. Do not tough hot surfaces on installation equipment. EMERGENCY AND FIRST AID PROCEDURES Eyes: If eye irritation occurs, hold eyelids apart and flush affected area(s) with clean water. Seek medical attention. Skin: First aid is normally not required. After handling product, it is good work practice to wash your hands. If molten material contacts skin, cool area immediately in water. DO NOT attempt to remove material from the skin. Treat as a burn, and seek medical attention. Ingestion: Not a normal route of exposure. However, if swallowed and symptoms develop, seek medical attention. Inhalation: If respiratory symptoms or other symptoms of exposure develop, more victim to fresh air. If symptoms persist, seek medical attention. If breathing difficulties develop, oxygen should be administered by qualified personnel. Seek immediate medical attention. If victim is not breathing, immediately begin artificial respiration. Keep victim warm and quiet, seek immediate medical attention. Steps to be Taken in Case of Release or Spill: Wear appropriate personal protection when responding then sweep up and collect in a suitable container for disposal or reuse. Unusual Fire and Explosion Hazards: Toxic fumes may be given off in a fire. See also sections on Thermal Degradation and Combustion Byproducts and Other Precautions. Special fire Fighting Procedures: Firefighters should wear self-contained breathing apparatus with a full face piece operated in the positive demand mode when fighting fires.
