- TECHNICAL DATA SHEET: KEY CHARACTERISTICS AND APPLICATIONS​

Chlorinated Polyvinyl Chloride (C-PVC)

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.

Note: This technical data sheet provides a general overview and typical properties of C-PVC. Actual specifications might differ depending on the manufacturer and specific grade of the material. Always refer to the manufacturer’s data sheets for accurate details on a particular product.
