Polyurethane vs. Pvc — What's the Difference?
By Urooj Arif & Fiza Rafique — Updated on March 28, 2024
Polyurethane is a versatile, durable plastic used in various applications, offering elasticity and chemical resistance, while PVC, or Polyvinyl Chloride, is a rigid, cost-effective plastic commonly used in construction and piping.

Key Differences
Polyurethane is known for its flexibility, toughness, and resistance to abrasion and various chemicals, making it ideal for high-wear applications such as wheels, hoses, and coatings. On the other hand, PVC is celebrated for its strength, durability, and resistance to environmental factors, making it a staple in the construction industry for pipes, window frames, and doors.
Polyurethane's elasticity allows it to be used in a wide range of flexible products, from foam mattresses to automotive interiors. Whereas PVC's rigidity is suited for applications requiring structural integrity, such as water pipes and vinyl siding.
While polyurethane can be more expensive due to its manufacturing process and the raw materials used, its durability and flexibility can lead to longer product life spans, offsetting the initial cost. PVC, on the other hand, is generally more affordable and easier to manufacture, making it a popular choice for budget-conscious projects.
Polyurethane is often chosen for its aesthetic qualities, as it can be formulated in various colors and finishes. PVC, while also available in different colors, is more commonly found in its natural white or grey state, particularly in construction materials.
The environmental impact of both materials varies; polyurethane is difficult to recycle due to its cross-linked structure, making disposal and recycling a challenge. PVC, although recyclable, releases harmful chemicals if not properly handled or disposed of, posing environmental concerns.

Polyurethane
Polyurethane (often abbreviated PUR and PU) is a polymer composed of organic units joined by carbamate (urethane) links. In contrast to other common polymers such as polyethylene and polystyrene, polyurethane is produced from a wide range of starting materials (monomers) and is therefore a class of polymers, rather than a distinct compound.
Pvc
A polymer of vinyl chloride used instead of rubber in electric cables
Polyurethane
A synthetic resin in which the polymer units are linked by urethane groups, used chiefly as constituents of paints, varnishes, adhesives, and foams
Five coats of polyurethane
Polyurethanes serve a variety of uses
Pvc
Irregularity of cardiac rhythm; recurrent occurrences can be a precursor of ventricular fibrillation
Polyurethane
Coat with polyurethane paint or varnish

Polyurethane
Any of various thermoplastic isocyanate polymers, widely varying in flexibility, used in tough chemical-resistant coatings, adhesives, and foams.
Polyurethane
(organic chemistry) Any of various polymeric resins containing urethane links; used in very many industrial and domestic applications.
Polyurethane
Any polymer containing [-NH.CO.O-] linkages; such polymers are much used as the basis of light but rigid foams for packaging (polyurethane foam) and for hard coatings, as on floors.
Polyurethane
Any of various polymers containing the urethane radical; a wide variety of synthetic forms are made and used as adhesives or plastics or paints or rubber
