CPVC PLASTIC MATERIAL & MACHINING
CHEMICALLY RESISTANT MATERIAL WITH A HIGH HEAT DISTORTION TEMPERATURE
CPVC (chlorinated polyvinyl chloride) is a "powered-up" version of the conventional PVC. Due to the addition of chlorine molecules to the polymer, it can withstand high functional temperatures and exposure to corrosive chemicals better than its conventional version. However, it still keeps a comparable strength and fire resistance level as well as electrical insulation to its unchlorinated form.
Typically, CPVC is used for hot water transport, industrial liquid handling, and similar applications. As CPVC offers a high heat distortion temperature, it can handle functional temperatures between 90-93°C (~194-200°F).
CPVC is generally light yellow or light grey, and common applications include pipes, fittings, valves, and ducts.

Properties & Characteristics
CPVC is a relatively low-cost material with a wide variety of applications. Due to its high heat distortion temperature, chemical inertness, and flammability properties, CPVC is a popular choice for applications that require a cost efficient material for non-medical applications.
While still maintaining PVC's great strength and impact resistance, CPVC includes an enhanced ability to not only withstand higher temperatures but also resist a wide range of chemicals. Its chlorination lends this material higher protection against acids, bases, salts, and other corrosive substances. If the product needs to withstand exposure to aggressive chemicals, designers should consider using CPVC.
In that vein, CPVC generally does not support combustion due to its fire retardant properties. Its low heat release rate contributes to the material's widespread use in fire sprinkler systems among other applications where fire safety needs consideration.
Among its uses in fire safety, CPVC also features a low thermal conductivity rate. This grants the material electrical insulation properties that surpass other materials.
