Specific Weight of PVC: Weight of 1 m³, PVC Density and Reference Table
PVC (polyvinyl chloride) is a thermoplastic polymer of vinyl chloride. Depending on its formulation and additives, the material may be transparent, translucent or opaque. PVC is produced by suspension, emulsion or bulk polymerization of vinyl chloride.
The material is highly resistant to most acids, alkalis, mineral oils and many solvents. It also offers good mechanical properties, relatively limited frost resistance and belongs to the group of flame-retardant plastics with self-extinguishing properties once the ignition source is removed.
PVC is widely used to manufacture pipes, sheets, various types of films including stretch ceiling films, artificial leather, linoleum, edge banding, PVC fibers, window and door profiles, as well as numerous accessories and clothing components.
When working with PVC it is important to understand its physical properties. One of the key characteristics is density, which makes it possible to determine the weight of a given volume of material.
PVC Density Table
Although many users search for the “specific weight of PVC”, engineering calculations usually rely on the material’s density. It cannot be measured accurately without laboratory equipment, but its average reference values are well established.
Specific Weight and Weight of 1 m³ of PVC
| Material | Density (g/cm³) | Weight of 1 m³ (kg) |
|---|---|---|
| PVC | 1.34–1.40 | 1340–1400 |
The exact value depends on the PVC grade, fillers, plasticizers and temperature.
Specific Weight Calculation
Specific weight is the ratio of weight to volume and is calculated using:
γ = ρ × g
where γ is the specific weight, ρ is density and g is the gravitational acceleration (9.81 m/s²).
In practical engineering and construction, density expressed in kg/m³ is used much more often than specific weight.
If you need to determine the weight of a PVC sheet, first calculate its volume (length × width × thickness), then multiply the result by the material density.
PVC Density
Density represents the amount of mass contained in one cubic meter of material. It varies depending on temperature, formulation and additives.
For most rigid PVC grades, density ranges from 1.34 to 1.40 g/cm³, which corresponds to 1340–1400 kg/m³.
Conclusion
The average density of PVC is approximately 1.34–1.40 g/cm³, while one cubic meter typically weighs 1340–1400 kg. For accurate engineering calculations, always use the technical data provided for the specific PVC grade being used.
Frequently Asked Questions
Can the density of PVC be used for precise calculations?
The density and weight values for PVC in this article are reference values. They are suitable for preliminary estimates, but design, construction, production and other critical calculations should be checked against standards, material datasheets or measurement results.
Why can the actual weight of PVC differ from the table?
The actual weight of PVC depends on composition, moisture, temperature, porosity, fraction size, material grade and measurement conditions. Because of this, real values may differ from the average table data.
How do you calculate the mass of PVC from density?
For an approximate calculation, use the formula: mass = density × volume. If the density of PVC is given in kg/m³ and the volume is in m³, the result will be in kilograms.
