2. Chlorinated polyvinyl chloride - Wikipedia

   en.wikipedia.org/wiki/Chlorinated_polyvinyl_chloride

   CPVC sprinkler pipe inside a firestop mock-up. Chlorinated polyvinyl chloride (CPVC) is a thermoplastic produced by chlorination of polyvinyl chloride (PVC) resin. CPVC is significantly more flexible than PVC, and can also withstand higher temperatures. Uses include hot and cold water delivery pipes and industrial liquid handling.

3. Polyvinyl chloride - Wikipedia

   en.wikipedia.org/wiki/Polyvinyl_chloride

   In a fire, PVC can form hydrogen chloride fumes; the chlorine serves to scavenge free radicals, making PVC-coated wires fire retardant. While hydrogen chloride fumes can also pose a health hazard in their own right, it dissolves in moisture and breaks down onto surfaces, particularly in areas where the air is cool enough to breathe, so would ...

6. Thermoplastic - Wikipedia

   en.wikipedia.org/wiki/Thermoplastic

   Chlorinated polyvinyl chloride (CPVC) is produced through exposing PVC to the continued free-radical chlorination reaction that originally formulates the PVC polymer. The chlorination reaction continues to add chlorine atoms to the polymer hydrocarbon backbone until most commercial applications reach a percent range between 56 and 74% total ...

   en.wikipedia.org/wiki/Plasticizer

   PVC, used extensively in sewage pipes, is only useful because of plasticizers. [1] A plasticizer (UK: plasticiser) is a substance that is added to a material to make it softer and more flexible, to increase its plasticity, to decrease its viscosity, and/or to decrease friction during its handling in manufacture.
