Components (Remarks)

Material is not known to contain Toxic Chemicals under Section 313
of Title III of the Superfund Amendments and Reauthorization Act
of 1986 and 40 CFR part 372.

Additives in this product do not present a respiration hazard
unless the product is ground to a powder of respirable size and
the dust is inhaled. All dusts are potentially injurious to the
respiratory tract if respirable particles are generated and
inhaled in sufficiently high concentrations. Good industrial
hygiene practices, as with all dusts, should include precautions
to prevent inhalation of respirable particles.

----------------------------------------------------------------------
HAZARDS IDENTIFICATION
----------------------------------------------------------------------
Potential Health Effects

"VESPEL" and "ZYMAXX" parts and shapes are not hazardous as
shipped.


PFA

Inhalation of PFA dust may cause generalized irritation of the
nose, throat and lungs with cough, difficulty breathing or
shortness of breath.

Heating PFA 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 PFA heated above 400
degrees C may cause pulmonary inflammation, hemorrhage or edema.
These more serious consequences of exposure may occur from extreme
thermal decomposition of PFA 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,
VSP026 DuPont Performance Elastomers L.L.C. Material Safety Data Sheet

(HAZARDS IDENTIFICATION - Continued)

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.

No skin irritation is expected during routine or occasional
handling of PFA. Prolonged skin contact may cause mild skin
irritation. Significant skin permeation after contact appears
unlikely. There are no reports of human sensitization.

If particles of PFA 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.

CARBON FIBE
Skin contact with Carbon Fibers may cause mechanical irritation of
the skin with itching, redness, swelling or rash. Contact
dermatitis with itching or rash, inflammatory eruptions and drying
of the skin have been reported after contact with Carbon Fibers.

Eye contact with Carbon Fibers may cause eye irritation with
discomfort, tearing, or blurred vision.

FIBROUS GLASS

The mechanical action of the sharp fibers from Fiber Glass may
cause skin irritation with discomfort or rash.

Eye contact with Fiber Glass particles may cause mechanical eye
irritation with discomfort, tearing, or blurring of vision.

Inhalation of Fiber Glass particles may cause irritation of the
upper respiratory passages, with coughing and discomfort.

Results from epidemiology studies suggest no causal relationship
between Fiber Glass exposure and cancer. One epidemiology study
does indicate a slight increase in lung cancer deaths. The
evidence that fiber glass is related to these increased lung
cancer deaths is considered weak.

Individuals with preexisting diseases of the lungs may have
increased susceptibility to the toxicity of excessive exposures.

PARA-ARAMID RFP
VSP026 DuPont Performance Elastomers L.L.C. Material Safety Data Sheet

(HAZARDS IDENTIFICATION - Continued)

The mechanical action of the para-aramid RFP may cause slight skin
irritation at clothing binding points and mild irritation of the
eyes and nasal passages. Skin sensitization has not been observed
in human skin tests.

Based on animal experiments, long term exposures to high airborne
concentrations of para-aramid RFP could lead to pulmonary
inflammation and subsequent development of chronic lung disease.

After a through evaluation, IARC has concluded that there is
inadequate evidence in humans and in experimental animals for the
carcinogenicity of para-aramid fibrils. Thus, according to IARC,
para-aramid fibrils cannot be classified as to their
carcinogenicity in humans.

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.

----------------------------------------------------------------------
EXPOSURE CONTROLS/PERSONAL PROTECTION
----------------------------------------------------------------------
Engineering Controls

If parts require cleaning after dry machining, rinse with DI
water. If parts require cleaning after wet machining, remove
cutting fluids with soap and water.

Note: Any processes that have the potential to generate
dust, for example, cutting, machining or grinding, should be
performed using engineering controls, such as isolation,
enclosures, local exhaust ventilation, wetting with coolant,
or dust collection systems, to control airborne fibers and
dusts below applicable limits.

Note: Wet machining is the preferred method since the
liquid both cools the parts and reduces dust generation.
Aqueous-based coolants are preferred. Organic-based cutting
fluids may degrade the in-use performance of the product and
should not be used. Clean parts after cutting or before
use.

As with any wet machining technique, mist collection systems
should be used.

Skin that becomes contaminated with fibers and dusts should
be promptly washed with soap and water.

TOXICOLOGICAL INFORMATION
----------------------------------------------------------------------
Animal Data

PFA
Oral LD50: > 11,000 mg/kg in rats

There was no skin irritation after dermal injection of extracts
from PFA into rabbits.

The effects in animals from a single inhalation exposure to
thermal decomposition products of PFA include congestion, edema,
and hemorrhage of the lungs.

Administration of oral doses of PFA equivalent to the LD50
produced body weight losses, congestion and other nonspecific
effects. Repeated administration with 25% and 10% PFA in an oral
feeding study did not produce any effects in rats.

No animal test reports are available to define carcinogenic,
mutagenic, developmental, or reproductive hazards.

Carbon Fibers
Carbon fiber, tested as filament bundles, was not a skin irritant
in rabbits, but was a severe eye irritant in rabbits.

Guinea pigs exposed repeatedly by inhalation to approximately the
AEL had no abnormal histopathology. Long term exposure of rats
produced a reduction in body weight gain and a decrease in
absolute lung weights, but there was no effect suggesting systemic
toxicity or pulmonary dysfunction.

Tests in animals demonstrate no carcinogenic activity. Tests for
developmental or reproductive toxicity have not been performed.

Carbon Fibers did not produce genetic damage in bacterial or
mammalian cell cultures.

Fiber Glass
Skin irritation and mild eye irritation occurs in animals, but
these effects are attributed primarily to mechanical damage rather
than a chemical effect.

The effects in mice from single exposure by intratrachael
instillation with Fiber Glass include an inflammatory response.
Repeated inhalation exposures invoked pulmonary macrophage
reactions similar to biologically inert dusts.

Tests in some animals with Fiber Glass demonstrate carcinogenic
activity. However, these studies were by artificial implantation
or injection of fine glass fibers into the chest, abdominal
cavity, or trachea and are judged to be irrelevant to industrial
exposure. Chronic inhalation exposure of animals to fiber glass
at low concentrations produced minimal fibrosis in one study and
no adverse effects in a different study.
VSP026 DuPont Performance Elastomers L.L.C. Material Safety Data Sheet

(TOXICOLOGICAL INFORMATION - Continued)

No animal test reports are available to define mutagenic,
developmental, or reproductive hazards.

para-Aramid RFP
Oral ALD: > 7500 mg/kg in rats

para-Aramid RFP is not a skin irritant, and is not a skin
sensitizer in animals.

In a two week inhalation study, respirable para-aramid RFP at
concentrations of 1000-2000 fibrils per cubic centimeter of air
caused mild fibrosis, nonspecific effects such as weight loss, and
respiratory irritation but no effects at concentrations of 400
fibrils per cubic centimeter.

A two year inhalation study with para-aramid RFP (refined to
increase its respirable content) showed lung fibrosis at
concentrations of 25, 100 and 400 fibrils per cubic centimeter,
and lung lesions, previously identified as cystic keratinizing
squamous cell carcinomas, in some rats exposed to respirable
fibrils at concentrations of 100 and 400 fibrils per cubic
centimeter. To further characterize the latter lesions, a panel
of pathologists from North America and Europe diagnosed them as
"proliferative keratin cysts," and agreed that the lesions are not
malignant neoplasms and are most likely not neoplastic. This is a
unique type of lesion not found in humans and may be indicative of
a nonspecific biological response to the respirable material
rather than an indication of para-aramid RFP toxicity. No lung
fibrosis was seen in animals exposed to 2.5 respirable fibrils per
cubic centimeter for two years. In another study, no
intra-abdominal tumors were observed.

para-Aramid RFP did not produce genetic damage in bacterial or
mammalian cell cultures.

No animal test reports are available to define developmental or
reproductive hazards.
