Plastic Fabrication in the Manufacturing World Part 3: CPVC

This blog is the third part of a four-part series covering the plastics and polymers we work with at MultiSource Manufacturing LLC. The first two parts of this series covered polypropylene and PVC (polyvinyl chloride). While we briefly touched on chlorinated polyvinyl (CPVC) in the blog covering PVC, there is still a lot to understand about its properties and applications.


All the plastics we use to fabricate a broad range of components, parts, and full assemblies are sourced from quality providers so the MultiSource network can manufacture exactly what original equipment manufacturers (OEMs) and other customers need. Our expert engineers and technicians are highly experienced in a range of plastic fabrication processes, such as welding, forming, and bending, that include using CPVC in projects for multiple industries.


CPVC is a thermoplastic produced from chlorinating PVC resin. CPVC is very similar to PVC at a molecular level, but has many key differences that make it ideal for certain plastic fabrication processes.


Properties: CPVC is much more workable than its PVC counterpart. It can be easily machined, formed, and welded. Additionally, CPVC is highly resistant to corrosion at high temperatures up to 200°F. It’s a reliable plastic to use in the construction of self-supporting components that will be exposed to elevated temperatures. CPVC also holds up to corrosive temperatures in water that would damage other plastics. Like PVC, CPVC is resistant to fire, while also providing better insulation in piping than copper or other metals. In addition to being a better insulator, thermoplastic CPVC maintains water temperature without condensation on exterior piping. CPVC is more ductile than PVC, but has the same maximum pound per square inch (PSI) working pressure, making it ideal for high-stress, corrosive environments.


Applications: CPVC has many uses in plumbing and other pipe systems. Because of its resistance to corrosion, CPVC is a critical plastic in many sewage systems and chemical processing settings. It’s also a safe plastic to use in the food processing industry. CPVC piping is heavily implemented in drinking water treatment plants as well as the dairy and beverage industries. Residential, commercial, and industrial plumbing systems widely utilize CPVC piping. Plus, because it is durable, flexible, and corrosion resistant, it’s an ideal plastic for processing industrial and hazardous waste products. At MultiSource Manufacturing, we use CPVC in many parts and full assemblies, from piping and tubes in medical devices to sanitary food packaging equipment.


The use of CPVC has been consistent since the 1960s when Geneva Products developed the process for chlorinating PVC to use in distributing hot and cold water throughout its Michigan facilities.
