13 Stability
13.1. Stable under normal conditions.
14 Polymerization
14.1. Hazardous polymerization does not occur.
15 Conditions to Avoid
15.1. Instantaneous temperatures above 235 C(455 F), prolonged
heating at processing temperatures, or excessive shear/heat
combinations during processing can generate hazardous decomposition
products.
16 Hazardous Decomposition Products
16.1. 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.
17 Incompatible Materials
17.1. 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
