CPVC: The Material That Makes the Difference (If You Know How to Process It)

Chlorinated polyvinyl chloride (CPVC) stands out among technical polymers for its high performance under critical conditions. However, to achieve truly reliable and durable results, in-depth knowledge and careful processing are essential.

Outstanding Performance at High Temperatures

With a chlorine content of up to 69%, CPVC maintains its mechanical strength even at 95°C under pressure. This makes it suitable for demanding applications such as industrial piping, fire protection systems and chemical transport.

Excellent Chemical Resistance

CPVC is resistant to a wide range of aggressive agents, including acids, bases, salts and oxidizers. It is therefore a trusted material in environments where durability and safety are critical.

Simple and Safe Installation

One of the most appreciated features of CPVC is the simplicity of its joining process. Solvent cement alone is sufficient to create permanent joints, without the need for welding or specialized tools. This reduces operational risks and installation time on site.

Low Permeability and UV Resistance

Compared to polyolefins, CPVC has a lower permeability coefficient, limiting the penetration of oxygen and external contaminants. In addition, while it may yellow over time, it retains its mechanical properties when exposed to UV radiation.

Processing CPVC: Precision Matters

Extruding CPVC requires tight process control. Key aspects to consider include:

• Lower processing temperatures to prevent dechlorination
• Higher torque levels due to increased material viscosity
• Reinforced gearboxes to withstand mechanical loads

Focus on Compound Quality

Not all CPVC compounds are created equal. Formulations can vary widely between manufacturers. To ensure high-performance pipe production, compounds must contain efficient stabilizers, balanced lubricants and adequate impact modifiers.
