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.

It is used to help maintain the temperature of its contents, keeping cold items cold, and hot items hot. Insulated bags have been in use for many years in industry, medical/pharmaceutical use, food delivery, lunch bags, etc. Several designs have been available. [1] [2] [3] [4]
The container is cooled for as long as there is frozen gas available in the system. These have been used in railcars for many years, providing up to 17 days temperature regulation. [ 4 ] Whilst refrigerated containers are not common for air transport, total loss dry ice systems are usually used. [ 3 ]

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 ...
A cold chain is a supply chain that uses refrigeration to maintain perishable goods, such as pharmaceuticals, produce or other goods that are temperature-sensitive. [1] Common goods, sometimes called cool cargo, [2] distributed in cold chains include fresh agricultural produce, [3] seafood, frozen food, photographic film, chemicals, and pharmaceutical products.

Each reefer container unit is typically designed with a stand-alone electrical circuit and has its own breaker switch that allows it to be connected and disconnected as required. In principle each individual unit could be repaired while the ship was still underway. Refrigerated cargo is a key part of the income for some shipping companies.
