Overview
PVC (Polyvinyl Chloride) is a widely used thermoplastic known for its rigidity, chemical resistance and excellent electrical insulation properties. It is inherently flame-retardant and suitable for use in a wide range of industrial and commercial applications. Due to its strength and low moisture absorption, it performs well in corrosive environments and is commonly fabricated into tanks, ductwork and protective enclosures. PVC is easy to weld and bond and offers good dimensional stability, making it ideal for precision-fabricated assemblies.
Key Features
- Rigid and dimensionally stable
- Flame retardant (self-extinguishing)
- Excellent electrical insulation
- Good chemical resistance to acids, bases and salts
- Low moisture absorption
- Easy to weld, glue and fabricate
- Good mechanical strength
- Cost-effective
Applications
- Chemical tanks and containment structures
- Ventilation ducts and fume extraction systems
- Electrical panels and enclosures
- Piping for water treatment and chemical handling
- Cable management systems
- Laboratory equipment housing
- Machine guarding and safety barriers
Weaknesses
- Limited temperature resistance (softens around 60–80°C)
- Becomes brittle at low temperatures
- Poor UV resistance (requires stabilizers for outdoor use)
