Polyvinyl chloride (PVC) is one of the most versatile thermoplastics being used today. It is used extensively in all industries from food packaging, to home construction. Its excellent strength-to-weight ratio and superior flame resistance, coupled with its low cost, make it the material of choice for the most demanding applications. PVC or “vinyl” is 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 (60°C). 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. Type I rigid PVC is a high corrosion resistant material with normal impact properties and is used where chemical attack is the major concern. Type II is an impact modified formula, which increases the ability of the material to withstand shock or impact, but will have lower chemical resistance relative to Type I. Physical properties of rigid PVC generally conform to ASTM-D-1784 (ISO 1163).
Technology has created the ability to foam both flexible and rigid PVC. The most significant growth has been in the lines of foamed rigid PVC. The process of foaming reduces the density of the PVC by 50 percent or more, which significantly impacts weight and cost, while still maintaining good physical properties. This class of products has seen significant growth in a relatively short period of time. It has replaced materials such as wood, metal, acrylic and styrene. It is used in many of the same applications as traditional PVC, but because of its lower cost, it is now the material of choice for point-of-purchase applications, signage and building construction.
PVC is extremely useful in applications where electrical conductivity is prohibited. Applications such as conduits (underground or within a building), special factory floors, electrical device mounts, insulation material and more make PVC the ideal choice material.
