What is Polyvinyl Chloride (PVC)?

Polyvinyl chloride is a popular thermoplastic used extensively in many industries. It is strong, rigid, and offers excellent resistance to chemicals and corrosion. PVC is easy to thermoform and bonds well with adhesives and solvents, making it a convenient material to work with.

Its low cost coupled with its high strength-to-weight ratio makes it an attractive option for demanding applications. Additionally, it is a good electrical and thermal insulator.

Maximum service temperature: 140°F (60°C)

Material advantages

• Chemical and corrosion resistant
• Cost-effective
• High strength-to-weight ratio
• Easy to fabricate, weld, and machine
• High heat distortion

Similar to other plastics, polyvinyl chloride has several compounds engineered for stronger performance in specific applications. There are three general classifications for rigid PVC compounds: Type I, Type II, and CPVC.

They are created with the addition of plasticizers, stabilizers, and colorants, which alter the physical properties of PVC. The compounds share many of the same properties, but they do possess unique distinguishing attributes.

PVC fittings

PVC Type I 

PVC type I is utilized for its excellent chemical and corrosion resistance. It has normal impact properties, so it is best used in applications where the final installation is not subject to intense contact. This PVC is easy to fabricate, weld and machine.

Applications

• Corrosive-resistant valves and fittings
• Chemical processing equipment
• Pool components
• Laboratory equipment

PVC Type II

PVC type II is an impact-modified formula. It has an increased ability to withstand shock or impact, but in turn, loses some chemical resistivity. This PVC works well in thermoformed and vacuum-formed products.

Applications

• Consoles
• Acid baths
• Junction boxes
• Tanks and containers

Chlorinated Polyvinyl Chloride (CPVC)

CPVC is a further reacted form of PVC which offers enhanced temperature and chemical resistance. Products made from this material have a maximum service temperature of 200°F (93°C). Additionally, CPVC is significantly more flexible than PVC.

Applications

• Commercial plumbing
• Chemical processing
• Sprinkler systems
• Ventilation pipes
