10. STABILITY AND REACTIVITY (Continued)
Incompatible Materials
Polyvinyl chloride compounds should not come into contact with acetal or acetal copolymers in elevated temperature
processing equipment. The two materials are not compatible and will react in a violent decomposition when mixed under
conditions of heat and pressure.
11. TOXICOLOGICAL INFORMATION
The following information on polyvinyl chloride is extracted from both the HSDB and NTP databases.

TD
LO
= Lowest toxic dose in a given species by a given route of exposure.
LC
50
= 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.
12. ECOLOGICAL INFORMATION
Environmental Fate:
Aquatic: No data available
Biodegradation: Not subject to biodegradation
Ecotoxicity: Based on the high molecular weight of this polymeric material, transport of this compound across
biological membranes is unlikely. Accordingly, the probability of environmental toxicity or
bioaccumulation in organisms is remote. Due caution should be exercised to prevent the
accidental release of this material to the environment.
