Specific Weight of Polyethylene: Density and Weight of 1 m³
Polyethylene is one of the most widely used plastics in the world. It is used to manufacture films, packaging, pipes, containers, cable insulation and many other products.
Note: Polyethylene is often incorrectly referred to as “cellophane”. They are different materials.
Polyethylene Density Table
Despite the common search query “specific weight of polyethylene”, the table gives the density values of the material and the corresponding mass of one cubic meter.
| Material | Density (g/cm³) | Weight of 1 m³ (kg) |
|---|---|---|
| Polyethylene | 0.910–0.976 | 910–976 |
Specific Weight Calculation
Specific weight is calculated using the formula:
γ = ρ × gwhere γ is the specific weight, ρ is density, and g is gravitational acceleration (9.81 m/s²).
Density of Polyethylene
Polyethylene density depends mainly on the material grade, degree of crystallinity and temperature. For most industrial grades, it is within 0.913–0.973 g/cm³.
How to Use These Values
The values in the table are suitable for preliminary calculations of mass, volume, delivery and material comparison. If the calculation is related to purchasing, design, equipment selection or critical construction work, the data should be checked against the material data sheet, measurement conditions and manufacturer documentation.
Keep in mind that density and weight can change due to temperature, moisture, composition, material grade and measurement method. Reference values should be used as a practical estimate, not as the only source for an exact calculation.
Conclusion
One cubic meter of polyethylene typically weighs 910–976 kg, which corresponds to a density of 0.910–0.976 g/cm³.
Frequently Asked Questions
Can the density of polyethylene be used for precise calculations?
The density and weight values for polyethylene 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 polyethylene differ from the table?
The actual weight of polyethylene 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 polyethylene from density?
For an approximate calculation, use the formula: mass = density × volume. If the density of polyethylene is given in kg/m³ and the volume is in m³, the result will be in kilograms.
