Chlorinated polyvinyl chloride, or CPVC, is a thermoplastic which is produced by the post-chlorination of polyvinyl chloride (PVC) resin. CPVC typically contains 65-69% chlorine, compared to 55-57% for standard PVC. Its importance as an engineering thermoplastic is due to its relatively high glass transition temperature, high heat distortion temperature and chemical inertness; it also has outstanding mechanical, dielectric, and flame and smoke properties.

Lubrizol’s history with the production of CPVC dates back to 1959 and in the subsequent decades it has pioneered the processing of the material. Lubrizol offers CPVC as resin, injection molding compounds and extrusion molding compounds.

Why TempRite^® CPVC

TempRite^® CPVC can be used as a single compound, but is also designed to have high compatibility with PVC and is easy to blend into existing PVC formulations.

It can be used in a variety of processing techniques including, but not limited to, injection and compression molding, and profile and sheet extrusion.

TempRite CPVC can also be used in adhesive formulations, where they can improve performance in various industry sectors and end-uses.

As a foam-based material, the product can be used to manufacture cores, e.g.: for Aluminium Composite Material (ACM) panels, where it offers excellent fire-resistance properties compared with traditional thermoplastics.

Its 65-69% chlorine content, compared to 55-57% for standard PVC, provides numerous material advantages:

High glass transition temperature

High heat distortion temperature

Chemical and Moisture inertness

Improved fire performance

Improved mechanical and dielectric properties

Corrosion Resistance

TempRite CPVC compounds can resist some of the harshest acids, alkalis, weather and other pollutants present in the atmosphere. CPVC is inert to all of the environmental factors that can corrode metals, including:

Oxygen combined with water
O3, or ozone
Salt air
Bacteria

Heat Resistance

TempRite^® compounds provide mid-range thermal performance and higher heat resistance than PVC. Therefore, they can extend high temperature performance and maintain shape and color without deformation, without adding excessive cost.

Fire and Smoke Performance

TempRite CPVC offer fire resistance due to reduced flame spread, smoke development resistance and lower smoke density. They can offer a cost-effective solution for fire performance, often reducing dependency on additional, costly additives. Our products are not only able to resist fire, but they are actually self-extinguishing under normal atmospheric condition of oxygen.
