Polyvinyl Chloride / PVC or Vinyl is usually an amorphous thermoplastic material with excellent chemical resistance and dielectric properties, good tensile, flexural and mechanical strength, low moisture absorption, exceptional dimensional stability and good flammability characteristics. The maximum service temperature for PVC is 140°F. The physical properties of PVC can be readily altered by the addition of plasticizers, impact modifiers and other ingredients to develop and enhance specific properties. Generally, there are two basic types of PVC available - Rigid PVC and Flexible (plasticized) PVC. Fabricated by hot gas welding, fusion, butt welding, ultrasonic sealing, die cutting, vacuum forming and thermoforming, and standard machining techniques.

PVC Type II, Grade I - is a high impact corrosion resistant polyvinyl chloride. Because of its excellent impact and ductility it is ideally suited for applications that require thermal forming or where the finished product is subject to shock or physical abuse.
