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
How much does 1 m³ of PVC weigh?
For rigid PVC grades, the article uses a reference range of 1340-1400 kg/m³. The exact value depends on formulation, plasticizers, fillers and the datasheet for the specific grade.
Why can PVC density vary?
Density changes with material composition: rigid and plasticized PVC, filler content and additives can give different values for calculations.
How do you calculate the weight of a PVC sheet?
Multiply the sheet length, width and thickness to get its volume, then multiply that volume by the density of the selected PVC grade.
Is PVC safe when heated?
Service properties depend on the formulation. When overheated or burned, PVC can release irritating decomposition products, so the datasheet and service conditions for the specific product should be considered.
