Various additives are also introduced into the resin in order to make the material processable. CPVC is similar to PVC in resistance to fire. Request Information . Elementary Principles of Chemical Processes. N/A 2 1/2 in63.5 mm Nominal Wall N/A 1/4 in6.4 mm Max. Fire properties[edit]. Additionally, the mechanical strength of CPVC makes it a viable candidate to replace many types of metal pipe in conditions where metal’s susceptibility to corrosion limits its use. Working Pressure at 70F (20C) N/A 35 psi Standard Length N/A 50 ft Approx. Due to its specific composition, dealing with CPVC requires a specialized solvent cement, with high strength solvent cement variants being first introduced in 1965 by Genova Products, then followed by other products such as IPS’s Weld-On line.

Chlorinated polyvinyl chloride Names Other names Polychloroethylene Identifiers CAS Number 68648-82-8[1] Abbreviations CPVC, PVC-C Properties Chemical formula for 67% Cl Polymer:(C9H11Cl7)n)[2] Except where otherwise noted, data are given for materials in their standard state (at 25C [77F], 100kPa). Heat resistance[edit]. This article needs additional citations for verification. 3A- The PVC compound complies with the criteria in 3-A Sanitary Standards for Multiple-Use Plastic Materials, number 20.FDA – The PVC ingredients used are sanctioned for food contact use under CFR title 21, parts 170-199.NSF – This tubing/hose is certified under NSF/ANSI standard 51: Food Equipment Materials.RoHS – The product complies with the requirements of the EU directive 2002/95/EC which is on the restriction of the use of certain hazardous substances in electrical and electronic equipment.UL – The clear PVC plastic material is certified for Flame Class HB under the Plastics – Components category by UL with a minimum thickness of 0.8 mm.USDA – The PVC hose has been found chemically acceptable for use in slaughtering, processing, transporting, or storage areas in direct contact with meat or poultry food product prepared under Federal Inspection.USP – The PVC compound has been tested and meets the requirements of the USP guidelines, for Class VI Plastics. It is also readily workable, including machining, welding, and forming. p.581. N/A 2.000 in50.80 mm Nominal O.D. CPVC can withstand corrosive water at temperatures greater than PVC, typically 40C to 50C (104F to 122F) or higher, contributing to its popularity as a material for water piping systems in residential as well as commercial construction. This reaction is typically initiated by application of thermal or UV energy utilizing various approaches.

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. ^ ^ Felder, Richard M.; Rousseau, Ronald W. bd40bc7c7a
