Polyvinyl Chloride (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. 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 plasticized PVC. Additional subcategories of rigid and flexible PVC with desirable physical properties targeted to a specific application can be developed by altering additives to the base resin (i.e., the addition of UV stabilizers to enhance weatherability of rigid vinyl siding used in outdoor applications, etc.). PVC is available in a wide spectrum of colors as well as transparent variations. PVC is manufactured into products by the injection molding process (e.g., pipe fittings), extrusion (e.g., pipe, shapes, siding, etc.), blow molding (e.g., bottles, etc.) and calendering (e.g., sheet). Joining and fabrication of PVC is readily accomplished by the solvent cementing process, thermal hot air welding, machining, thermoforming, and hot sheet welding. The wide range of formulations, processing characteristics, fabrication capabilities, durability and relatively stable cost provide an economical material for a broad range of applications.

Rigid PVC is the most common type of PVC used in the manufacture of pipe, fittings, valves, machining shapes, sheet and duct. Rigid PVC offers advantages for piping and related applications due to its low cost, high strength to weight ratio, pressure bearing capability, corrosion and chemical resistance and low friction loss characteristics.

The minimum physical properties of compounds for use to manufacture rigid PVC are called out in ASTM Standard D1784. Within this standard, the compounds are separated into cell classification numbers that reflect the actual minimum physical properties of the compound with regard to impact strength, tensile strength, modulus of elasticity, deflection temperature under load, flammability, and chemical resistance. Altering the amount of a specific ingredient to improve one desirable
property can affect other properties. For example, adding plasticizers to improve flexibility and impact resistance can result in a finished product with less rigidity and lower chemical resistance. The cell classification called out within this standard help define and establish a basis for selecting and identifying various grades of rigid PVC compounds for correlation to specific applications.

Flexible (plasticized) PVC is vinyl which has been heavily plasticized and is used to produce liners, film, packaging, wire and cable insulation jackets and many other products which require flexibility and resistance to tear, puncture and abrasion. As with rigid PVC, flexible PVC can be formulated with additives to achieve desirable physical characteristics for specific applications and can be easily fabricated.

PVC Clear Sheet
Clear PVC sheet is water-clear and masked on two sides.

PVC Sheet Type I
Extruded PVC sheet has normal impact and high corrosion resistance and comes in a dark gray color. This material meets federal specification L-P-535E. Press laminated PVC sheet offers normal impact and high corrosion resistance and is available in thick gauges. It comes in a dark gray color. Other sizes are available on special quotation. Sold in standard sheets only, the thick gauges come one sheet per case.

PVC Type II Sheet
PVC Type II sheet has the same properties as regular PVC. However, it has been modified to provide higher impact strength. It is available in a light gray color.

PVC rod is type I, grade I. It has normal impact and normal corrosion resistance. Available in a dark gray color, the rod has unground diameters. Red and white colors available in selected sizes, please call your customer service representative for availability.
