Complete Guide on CPVC (Chlorinated Polyvinyl Chloride): Types, Uses, Market, and More
1. What is CPVC?
CPVC (Chlorinated Polyvinyl Chloride) is a thermoplastic produced by the chlorination of PVC resin. The added chlorine increases its heat resistance, chemical stability, and mechanical strength—making it ideal for hot and cold water distribution, industrial piping, and fire sprinkler systems.
2. Types & Grades of CPVC
| Type | Description |
|---|---|
| CPVC Resin | Base material for compounding and molding |
| CPVC Compound | Ready-to-use blend of resin + additives |
| CPVC Pipes & Fittings | Final products used in plumbing and industry |
| Recycled CPVC | Used in non-critical, cost-effective applications |
3. Key Properties of CPVC
| Property | Typical Value |
|---|---|
| Chlorine Content | 63%–69% |
| Service Temperature | Up to 93°C (200°F) |
| Tensile Strength | 55–60 MPa |
| Vicat Softening Point | ~110°C |
| Flame Resistance | Self-extinguishing (UL 94 V-0) |
| Chemical Resistance | Excellent (acids, alkalis, etc.) |
| Thermal Insulation | Superior to metal piping |
