PVC Characteristics

PVC (polyvinyl chloride) is one of the most widely used thermoplastics on the market. Its superior combination of properties and its low cost make it an easy choice for many applications.

PVC offers excellent chemical and flame resistance, strength-to-weight ratio and dielectric properties along with good tensile, flexural and mechanical strength, low moisture absorption and exceptional dimensional stability. In addition, it is easily altered by the addition of plasticizers, impact modifiers and other ingredients.

PVC can be used in the most demanding applications including food processing and is available in both rigid and flexible formulations.

  • Economical
  • Easily welded or bonded
  • Good dimensional strength
  • Resistant to chemicals and corrosion
  • Good electrical and thermal insulator
  • Low water absorption
  • UL94-VO fire rating
  • FDA approved
