Chlorinated polyvinyl chloride CPVC is a thermoplastic produced by chlorination of polyvinyl chloride PVC resin which is significantly more flexible and can withstand higher temperatures than standard PVC. Uses include hot and cold water pipes, and industrial liquid handling. HistoryeditGenova Products located in Michigan initially created the first CPVC tubing and fittings for hot and cold water distribution systems in the early 1. The original tetrahydrofuran THF methyl ethyl ketone MEK formulas for CPVC cements were developed by Genova in conjunction with the B. The American business community was also very impressed with the propaganda effort. They had a problem at that time. The country was becoming formally more democratic. Chlorinated polyvinyl chloride CPVC is a thermoplastic produced by chlorination of polyvinyl chloride PVC resin which is significantly more flexible and can. F. Goodrich Company, the original developer of the CPVC resin. Production processeditChlorinated polyvinyl chloride CPVC is PVC polyvinyl chloride that has been chlorinated via a free radical chlorination reaction. This reaction is typically initiated by application of thermal or UV energy utilizing various approaches. In the process, chlorine gas is decomposed into free radical chlorine which is then reacted with PVC in a post production step, essentially replacing a portion of the hydrogen in the PVC with chlorine. Depending on the method, a varying amount of chlorine is introduced into the polymer allowing for a measured way to fine tune the final properties.

As the chlorine content in CPVC is increased, its glass transition temperature Tg increases significantly. Under normal operating conditions, CPVC becomes unstable at 7. Various additives are also introduced into the resin in order to make the material processable. These additives may consist of stabilizers, impact modifiers, pigments and lubricants. Physical propertieseditCPVC shares most of the features and properties of PVC. It is also readily workable, including machining, welding, and forming. Because of its excellent corrosion resistance at elevated temperatures, CPVC is ideally suited for self supporting constructions where temperatures up to 2. F 9. 0 C are present. Due to its specific composition, dealing with CPVC requires a specialized solvent cement, with high strength solvent cement variants being first introduced in 1. Genova Products, then followed by other products such as IPSs Weld On line. The ability to bend, shape, and weld CPVC enables its use in a wide variety of processes and applications.

Comparison to polyvinyl chloride PVCeditHeat resistanceeditCPVC can withstand corrosive water at temperatures greater than PVC, typically 4. Progea Movicon'>Progea Movicon. Western Wood Products Association, representing Western lumber manufacturers. He sold me on the idea of a very simple system. The plan called for a boiler to supply hot water at up to 180 degrees and then it is mixed down to around 100 degrees.

F or higher, contributing to its popularity as a material for water piping systems in residential as well as commercial construction. Mechanical propertieseditThe principal mechanical difference between CPVC and PVC is that CPVC is significantly more ductile, allowing greater flexure and crush resistance. Additionally, the mechanical strength of CPVC makes it a viable candidate to replace many types of metal pipe in conditions where metals susceptibility to corrosion limits its use. Fire propertieseditCPVC is similar to PVC in resistance to fire. It is typically very difficult to ignite and tends to self extinguish when not in a directly applied flame. Due to its chlorine content, the incineration of CPVC, either in a fire or in an industrial disposal process, can result in the creation of chlorinated dioxins and the similarly dangerous Polychlorinated dibenzofurans, both which bioaccumulate.
