HAZARDS IDENTIFICATION
----------------------------------------------------------------------
Potential Health Effects
Skin contact may cause skin irritation with
discomfort or
rash. Prolonged skin contact may cause redness
and
inflammation of the hair follicles without
skin
sensitization.
Eye contact may cause eye irritation with discomfort,
tearing or blurring of vision.
Inhalation of fluorine compounds released as
decomposition
products above 290 degC (554 degF) may cause
lung irritation
and pulmonary edema which require medical treatment.
Inhalation of fumes or smoke from overheated
or burning
grease may cause polymer fume fever, a temporary
flu-like
illness accompanied by fever, chills, and sometimes
cough,
of approximately 24 hours duration. Repeated
episodes of
polymer fume fever may cause lung damage.
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.
----------------------------------------------------------------------
FIRST AID MEASURES
----------------------------------------------------------------------
First Aid
INHALATION
If inhaled, remove to fresh air. If not breathing,
give
artificial respiration. If breathing is difficult,
give oxygen.
Call a physician.
SKIN CONTACT
Flush skin with water after contact. Wash contaminated
clothing
before reuse.
EYE CONTACT
In case of contact, immediately flush eyes
with plenty of water
for at least 15 minutes. Call a physician.
INGESTION
If swallowed, do not induce vomiting. Immediately
give 2 glasses
of water. Never give anything by mouth to an
unconscious person.
Call a physician.
Notes to Physicians
Activated charcoal mixture may be administered.
To prepare
activated charcoal mixture, suspend 50 grams
activated charcoal in
400 mL water and mix thoroughly. Administer
5 mL/kg, or 350 mL
for an average adult.

compounds. Avoid breathing decomposition products.
----------------------------------------------------------------------
ACCIDENTAL RELEASE MEASURES
----------------------------------------------------------------------
Safeguards (Personnel)
NOTE: Review FIRE FIGHTING MEASURES and HANDLING
(PERSONNEL)
sections before proceeding with clean-up. Use
appropriate
PERSONAL PROTECTIVE EQUIPMENT during clean-up.
Accidental Release Measures
Place in container for disposal. Remove source
of heat
and flame.
----------------------------------------------------------------------
HANDLING AND STORAGE
----------------------------------------------------------------------
Handling (Personnel)
Avoid contact with eyes. Avoid contact with
skin. Wash
thoroughly after handling. Do not store or
consume food, drink or
tobacco in areas where they may become contaminated
with this
material.
Storage
Keep container tightly closed. Do not store
or consume food,
drink or tobacco in areas where they may become
contaminated with
this material.

product.
----------------------------------------------------------------------
EXPOSURE CONTROLS/PERSONAL PROTECTION
----------------------------------------------------------------------
Engineering Controls
Keep container tightly closed.
Keep away from heat and flames.
Personal Protective Equipment
EYE/FACE PROTECTION
Wear safety glasses or coverall chemical splash
goggles.
RESPIRATOR
Where the potential exists for exposure to
decomposition
products due to heating or elevated temperatures,
wear
NIOSH approved respiratory protection as appropriate.
PROTECTIVE CLOTHING
Where there is potential for skin contact have
available
and wear as appropriate, impervious gloves,
apron, pants,
and jacket.
Exposure Guidelines
Applicable Exposure Limits
PTFE
PEL (OSHA) : None Established
TLV (ACGIH) : None Established
AEL * (DuPont) : 10 mg/m3, 8 Hr. TWA, total
dust
5 mg/m3, 8 Hr. TWA, respirable dust
* AEL is DuPont's Acceptable Exposure Limit.
Where governmentally
imposed occupational exposure limits which
are lower than the AEL
are in effect, such limits shall take precedence.

PHYSICAL AND CHEMICAL PROPERTIES
----------------------------------------------------------------------
Physical Data
Melting Point : 320 C (608 F)
Solubility in Water : Negligible WT%
pH : Neutral
Odor : Odorless
Form : Solid, waxy grease
Color : White
Specific Gravity : 1.89-1.93 @ 24 deg C (75
deg F)
----------------------------------------------------------------------
STABILITY AND REACTIVITY
----------------------------------------------------------------------
Chemical Stability
Stable.
Incompatibility with Other Materials
None reasonably foreseeable.
Polymerization
Polymerization will not occur.
Other Hazards
Decomposition: Heating above 260-290 deg C
(500-554 deg F)
may form potentially toxic fluorine compounds.
Depolymerization may occur in the presence
of some metal
oxides at temperatures above 288 deg C (550
deg F).
Decomposition occurs at increasing rates as
temperature
is raised above 355 deg C (670 deg F).
----------------------------------------------------------------------
TOXICOLOGICAL INFORMATION
----------------------------------------------------------------------
Animal Data
Perfluoroalkylether:
Inhalation 4 hour ALC: 19.54 mg/l in rats
Skin absorption ALD: >17,000 mg/kg in rats
Oral ALD: >25,000 mg/kg in rats
The product contains a mild eye irritant. A
single
inhalation exposure to perfluoroalkylether
caused
nonspecific effects such as respiratory irritation.
Toxic
effects described in animals exposed to decomposition
products of perfluoroalkylether formed above
260 degC (500
degF) include lung irritation, irregular respiration,
tremors and increased liver weight. Pulmonary
edema and
death occurred in rats exposed to the decomposition
products
of perfluoroalkylether formed at around 290
degC (554 degF).
A single inhalation exposure to PTFE caused
irritation of
the lungs. A repeated ingestion exposure caused
no
significant toxicological effects. Long-term
ingestion
exposure caused altered white blood cell count.
