History of Polyvinyl Chloride (PVC)
The story of polyvinyl chloride begins in the 19th century with an accidental discovery. In 1872, German chemist Eugen Baumann observed a white solid forming inside a flask of vinyl chloride gas that had been exposed to sunlight. This was the first documented creation of PVC, though its potential was not realized for several decades.
In the early 20th century, multiple chemists attempted to commercialize PVC. Russian chemist Ivan Ostromislensky and German scientist Fritz Klatte both explored applications for this new polymer, but PVC’s rigidity and brittleness made it difficult to process and limited its industrial use.
The breakthrough came in 1926, when American chemist Waldo Semon developed a technique to plasticize PVC by incorporating additives such as dibutyl phthalate. This made the material more flexible, easier to shape, and suitable for a broader range of applications. Semon’s work led to significant patents and the commercial viability of PVC as a versatile plastic.
By the 1950s, PVC production surged as its properties—chemical resistance, durability, and processability—made it ideal for use in pipes, cables, and building materials. Innovations in formulation during the 1980s further improved its thermal resistance, expanding its use in plumbing systems, automotive parts, and even medical devices.
Today, polyvinyl chloride is produced by dozens of companies worldwide and stands as the third most widely manufactured plastic, after polyethylene and polypropylene. Its long journey from laboratory experiments to industrial powerhouse reflects the dynamic evolution of material science and the enduring relevance of PVC in modern society.
What is Polyvinyl Chloride (PVC)?
Polyvinyl Chloride (PVC) is a synthetic thermoplastic polymer formed by the polymerization of vinyl chloride monomers (VCM). It is a white, odorless, brittle material in its pure form, available as powder or granules, and known for its excellent chemical resistance, mechanical strength, flame retardancy, and affordability.

Key Properties of Polyvinyl Chloride (PVC)
The exceptional performance of Polyvinyl Chloride (PVC) across diverse industries can be attributed to its balanced set of physical, mechanical, and thermal properties. These characteristics are further unable through additives and modifications, making PVC a flexible solution for applications ranging from infrastructure to consumer products.
- Physical Properties
- Density:
PVC has a relative density ranging from 1.38 to 1.48 g/cm³, significantly higher than polymers like polyethylene (PE), which ranges from 0.95 to 0.96 g/cm³. This high density contributes to PVC’s rigidity and stability in structural applications. - Water Absorption:
With a water absorption rate as low as 0.0012% after 24 hours at 23°C, PVC is nearly impermeable to moisture, making it ideal for plumbing and outdoor applications. - Surface Hardness:
Rigid PVC measures approximately 80 on the Shore D hardness scale, indicating good resistance to surface deformation and physical impacts. In contrast, PE has a Shore D value around 60, which is significantly softer. - Coefficient of Friction:
The friction coefficient between PVC-to-PVC surfaces is 0.4—moderate compared to PE (0.25) and PA (0.3). This affects how PVC behaves in applications involving movement or contact.
- Mechanical Properties
- Tensile Strength:
PVC exhibits an ultimate tensile strength of around 52 MPa, which is higher than polyethylene (30 MPa) and ABS (35 MPa), showcasing its superior load-bearing capacity. - Elongation at Break:
Although PVC’s elongation at break (50–80%) is lower than PE (600–900%), it offers a good balance between flexibility and toughness for many structural and flexible applications. - Elastic Modulus:
- Tensile: 3.0–3.3 GPa
- Flexural: 2.7–3.0 GPa
These values demonstrate high stiffness and resistance to bending, which is ideal for window frames, conduit pipes, and construction panels.
