                              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.

                            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. 
 
Extinguishing Media: carbon dioxide X   water X  dry chemical X  foam X    
other__
