PVC

PVC (Polyvinyl Chloride)

PVC (polyvinyl chloride) is a synthetic polymer and one of the most widely used plastics globally. It is known for its chemical resistance, durability, and versatility. PVC is produced in two primary forms – rigid (unplasticized) PVC and flexible (plasticized) PVC, each with distinct properties and applications.

Types of PVC and Their Uses

• Rigid PVC (uPVC):
  • Excellent resistance to chemicals, aging, and UV exposure
  • Good thermal stability and weldability
  • Safe for potable water applications
  • Common uses: pipes, tanks, window frames
• Flexible PVC:
  • Made by adding plasticizers such as phthalates
  • Soft, flexible, waterproof
  • Common uses: hoses, flooring, waterproof fabrics

Disadvantages

When burned, PVC can release toxic gases such as hydrogen chloride. It is therefore not recommended for fire-prone environments.
