SECTION 2. HAZARDS IDENTIFICATION
Potential Health Effects
ADDITIONAL HEALTH EFFECTS
Before using read the Fluoropolymers Safe Handling Guide published by The Society of the
Plastics Industry.
The fluoroadditives in this MSDS may contain small amounts of hydrogen fluoride and
carbonyl fluoride, and additional amounts may be liberated upon heating, especially in the
presence of moisture. The primary hazard associated with these polymers is the inhalation of
fumes from overheating or burning, which may cause “polymer fume fever” (see HUMAN
HEALTH EFFECTS below).
POLYTETRAFLUOROETHYLENE (PTFE) Inhalation of PTFE dust may cause generalized
irritation of the nose, throat and lungs with cough, difficulty breathing or shortness of breath.
Heating PTFE above 300 degrees C may liberate a fine particulate fume. Inhalation may
produce polymer fume fever, a temporary flu-like condition with fever, chills, nausea,
shortness of breath, chest tightness, muscle or joint ache, and sometimes cough and elevated
white blood cell count. The symptoms are often delayed 4 to 24 hours after exposure. These
signs are generally temporary, lasting 24-48 hours and resolve without further complications.
However, some individuals with repeated episodes of polymer fume fever have reported
persistent pulmonary effects. Protection against polymer fume fever should also provide
protection against any potential chronic effects.
Exposure to decomposition products from PTFE heated above 400 degree C may cause
pulmonary inflammation, hemorrhage or edema. These more serious consequences of
exposure may occur from extreme thermal decomposition of PTFE which can liberate fume
particles, and toxic gases (carbonyl fluoride, hydrogen fluoride, and other fluorinated gases)
especially under conditions of poor ventilation and/or confined spaces. These decomposition
products may initially produce chest tightness or pain, chills, fever, nausea, with shortness of
breath, cough, wheezing and progression into pulmonary edema. Edema may be delayed in
onset and requires medical treatment. In severe cases, if medical intervention is delayed,
pulmonary edema may become life threatening. Recovery is generally complete within a few
days; in some rare cases, persistent lung function abnormalities have been reported.
Compared to nonsmokers, polymer fume fever symptoms appear to be more prevalent and
serious in smokers. Smokers must avoid contamination of tobacco with residual polymer
from their hands or from fumes, and should wash their hands before smoking.
Significant skin permeation, and systemic toxicity, after contact with the dust appears
unlikely. There are no reports of human sensitization from contact with the dust.
If PTFE dusts contact the eye, mechanical irritation with tearing, pain or blurred vision may
result.
Individuals with pre-existing diseases of the lungs or cardiovascular system may have
increased susceptibility to the reduction in blood oxygen that may develop after excessive
exposures to thermal decomposition products.
Carcinogenicity Information
None of the components present in this material at concentrations equal to or greater than
0.1% are listed by IARC, NTP, OSHA or ACGIH as a carcinogen.

SECTION 4. FIRST AIDMEASURES
INHALATION
No specific intervention is indicated as the compound is not likely to be hazardous by
inhalation. Consult a physician if necessary. If exposed to fumes from overheating or
combustion, move to fresh air. Consult a physician if symptoms persist.
SKIN CONTACT
The compound is not likely to be hazardous by skin contact, but cleansing the skin after use is
advisable. If molten polymer gets on skin, cool rapidly with cold water. Do not attempt to
peel polymer from skin. Obtain medical treatment for thermal burn.
EYE CONTACT
In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Call a
physician.
INGESTION
No specific intervention is indicated as compound is not likely to be hazardous by ingestion.
SECTION 5.FIRE-FIGHTINGMEASURES
Flammable Properties
Flash Ignition Temperature : 530-550℃ (986-1022℉)
Method : ASTM D1929
Self Ignition Temperature : 520-560℃ (968-1040℉)
Method : ASTM D1929
UL-94 Flammability Rating : V-O
Limiting Oxygen Index : >95
Method : ASTM D2863
Difficult to ignite, and flame goes out when initiating source is removed (UL-94). Limited
flame spread and low smoke generation (NFPA 262-1990, UL-910). Complied with NFPA
definition of “limited combustible” material. High self-ignition and auto-ignition
temperatures (ASTM D1929).
Hazardous gases/vapors produced in fire are hydrogen fluoride (HF), carbon monoxide,
potentially toxic fluorinated compounds.
Extinguishing Media
Water, Foam, Dry Chemical, CO2
Fire Fighting Instructions
Wear self-contained breathing apparatus. Wear full protective equipment. Hydrogen fluoride
fumes emitted during a fire can react with water to form hydrofluoric acid. Wear neoprene
gloves when handling refuse from fire.
SECTION 6.ACCIDENTAL RELEASEMEASURES
Safeguards (Personnel)
NOTE: Review FIRE FIGHTING MEASURES and HANDLING (PERSONNEL) sections
before proceeding with clean-up. Use appropriate PERSONAL PROTECTIVE EQUIPMENT
during clean-up.
Spilled material is a slipping hazard.
SECTION 7.HANDLING AND STORAGE
Handling (Personnel)
See FIRST AID and PERSONAL PROTECTIVE EQUIPMENT SECTIONS. Use only with
adequate ventilation. Avoid contact with eyes, skin, or clothing. Avoid breathing vapor or
dust. Avoid contamination of cigarettes or tobacco with dust from this material.
Handling (Physical Aspects)
Open container only in well-ventilate area. Do not use a torch to clean this material from
equipment without local exhaust ventilation and respirator.
Storage
Keep container closed to prevent contamination.
SECTION 8.EXPOSURE CONTROL/PERSONAL PROTECTION
Engineering Controls
VENTILATION Use local exhaust to completely remove vapors and fumes liberated during
hot processing from the work area. Use a totally enclosed system.
Personal Protective Equipment
EYE/FACE PROTECTION. Wear safety glasses. Wear coverall chemical splash goggles and
face shield when possibility exists for eye and face contact due to splashing or spraying of
molten material.
RESPIRATORS A respirator is not required if local exhaust ventilation is adequate. At
processing temperatures less than 250 deg C (480 deg F) a NIOSH/MSHA approved air
purifying respirator with dust/mist cartridge or canister may provide protection from airborne
particulates which cause polymer fume fever. At higher processing temperatures if ventilation
is inadequate to maintain hydrogen fluoride and carbonyl fluoride concentrations below
exposure limits, use a positive pressure air supplied respirator. Air purifying respirators may
not provide adequate protection.
PROTECTIVE CLOTHING If there is potential contact with hot/molten material, wear heat
resistant clothing and footwear.
SECTION 9.PHYSICAL AND CHEMICAL PROPERTIES
Physical Data
Melting Point : 320-342℃ (608-648℉)
Solubility in Water : Insoluble
Odor : None
Form : Powder
Color : White
Specific Gravity : 2.1-2.3
SECTION 10.STABILITY AND REACTIVITY
Chemical Stability
Stable at normal temperatures and storage conditions.
Incompatibility with Other Materials
Incompatible or can react with finely divided metal powder (e.g., aluminum and magnesium)
and potent oxidizers like fluorine (F2) and related compounds (e.g., chlorine trifluoride,
ClF3). Contact with incompatibles can cause fire, an explosion.
Decomposition
Heating above 300 deg C (572 deg F), may cause evolution of particulate matter which can
cause polymer fume fever (see HUMAN HEALTH EFFECTS). Small amounts of hydrogen
fluoride and carbonyl fluoride may be present in closed containers, and additional amounts
(maximum 0.055 wt% HF) may be evolved upon heating between about 250-400 deg C
(480-750 deg F), with larger amounts above 400 deg C (750 deg F).
SECTION 11.TOXICOLOGICAL INFORMATION
Animal Data
PTFE
Animal testing indicates that PTFE is not a skin irritant.
Repeated exposure to PTFE by ingestion caused no significant toxicological effects. Possible
effects on white blood cell counts were found in rats fed 25% PTFE in the diet for 90 days,
however any changes were within normal variability and were considered to be of no
toxicological significance.
In rats, single exposure to dusts of undegraded PTFE by inhalation caused irritation of the
lungs. Exposure to thermal decomposition products of PTFE caused lung injury whose
severity depends upon the temperature and exposure conditions. Birds appear to be especially
susceptible to the toxic effects of fluoropolymer decomposition products. In rats, exposure to
freshly formed low molecular weight polymer fragments (fume) produced by continuous
heating of the polymer above 400 degrees C may produce acute pulmonary inflammation.
When the concentration of fluoropolymer fragment fumes increases, deaths may occur from
pulmonary edema and hemorrhage. Exposure to fume aged for several minutes, markedly
reduces the toxicity. At higher temperatures involving gross thermal decomposition of the
polymer, deaths occurred due to pulmonary edema from lethal concentrations of
fluoropolymer fume and/or fluorinated gas decomposition products.
No adequate animal data are available to define the carcinogenicity or developmental hazards
of PTFE. No adequate reports of genetic testing were found. No animal data are available to
define the reproductive toxicity of PTFE.
