1. Stability
a. Stable under normal conditions.
2. Polymerization
a. Hazardous polymerization does not occur.
3. Conditions to Avoid
a. Instantaneous temperatures above 235°C(455°F), prolonged heating at
processing temperatures, or excessive shear/heat combinations during
processing can generate hazardous decomposition products.
4. Hazardous Decomposition Products
a. Overheating may cause thermal degradation of PVC compound. Fumes
and vapors (including CO, CO2, and HCl) may be generated during this
thermal degradation. Emissions are also possible during normal operating
conditions, and may accumulate within an inadequately ventilated facility.
5. Incompatible Materials
a. Do not allow this product to come in contact with acetal (POM) or acetal
copolymers within the extruder or molding machine. At processing
conditions, the two materials are mutually destructive and involve rapid
degradation of the products. Equipment should be purged with acrylic,
ABS, polystyrene, or other purge compound to avoid even trace amounts
of this product and acetals from coming in contact with each other.
The following information on polyvinyl chloride is extracted from both the HSDB and
NTP databases.
Animal Toxicity:
Oral: Rat, TDLO 210 gm/kg
Inhalation: Mouse, LC50 140 mg/M3/10M
TDLO = Lowest toxic dose in a given species by a given route of exposure.
LC50 = Concentration that is lethal to 50% of a given species by a given route of
exposure.
Rodents exposed to PVC by dietary or inhalation routes for 6 to 24 months have shown
no significant toxicological effects. While PVC is generally considered an inert polymer,
exposure to PVC dust has been reported to cause lung changes in animals and humans,
including decreased respiratory capacity and inflammation. However, exposures
approaching the nuisance dust exposure limits are not anticipated to pose a significant
health risk.
