General Information:

• Product Name: Chlorinated Polyvinyl Chloride (C-PVC)
• Classification: Thermoplastic polymer
• Chemical Structure: Derived from PVC by chlorination

Typical Properties:

• Density: 1.4 – 1.58 g/cm³
• Tensile Strength: 45 – 55 MPa
• Elongation at Break: 20 – 40%
• Tensile Modulus: 2,400 – 3,000 MPa
• Hardness: Shore D 80-90
• Melting Point: 190 – 210°C (374 – 410°F)
• Service Temperature: Up to 95°C (203°F)
• Water Absorption (24 hrs): < 0.04%
• Chemical Resistance: Superior to PVC; resistant to acids, alkalis, and select solvents.

Features and Benefits:

• Higher Temperature Resistance: C-PVC can withstand higher temperatures than regular PVC.
• Improved Chemical Resistance: Particularly resistant to acids, salts, bases, fats, and alcohols.
• Low Flammability: Self-extinguishing and doesn’t support combustion.
• Durability: Resistant to many corrosive environments.
• Low Thermal Expansion: Reduces the need for expansion loops and fittings.

Applications:

• Hot and Cold Water Distribution: For both residential and commercial settings.
• Industrial Piping Systems: Due to its chemical and temperature resistance.
• Fire Sprinkler Systems: Superior fire resistance compared to other materials.
• Cable Protection: Provides protection for electrical cables.
• Chemical Process Piping: Because of its excellent chemical resistance.

Processing Methods:

• Injection Moulding: Suitable for creating fittings and complex components.
• Extrusion: For pipes, profiles, and conduits.
• Solvent Welding: Commonly used to join C-PVC components.

Environmental Impact and Recycling:

• While C-PVC is durable and has a long lifespan, it is less frequently recycled than PVC due to the chlorination process.
• If recycled, it should be kept separate from PVC to prevent contamination.

Storage and Handling:

• Store C-PVC in a cool, dry environment away from direct sunlight to prevent degradation.
• C-PVC is non-hazardous; however, when processing, ensure proper ventilation to avoid inhalation of any potential fumes.

Safety Information:

• Solid C-PVC is non-toxic; however, when heated or burned, it can release chlorine gas, which is harmful.
• Always ensure proper ventilation during processing or welding.
