Nylon Grades & Density Values
Nylon (polyamide) is one of the most widely used engineering plastics, prized for its toughness, low friction, and excellent wear resistance. Density varies meaningfully across grades — using the wrong value leads to significant weight estimation errors.
| Grade | Abbreviation | Density (g/cm³) | Typical Use |
|---|---|---|---|
| Nylon 6 | PA6 | 1.14 | Gears, bearings, bushings, film |
| Nylon 6/6 | PA66 | 1.15 | Automotive parts, electrical connectors |
| Glass-Filled Nylon 30% | PA66-GF30 | 1.37 | Structural parts, housings, brackets |
| Cast Nylon | MC Nylon | 1.16 | Large blocks, rods, sheaves, wear pads |
How Nylon Weight Is Calculated
Weight Formula
Weight (g) = Volume (cm³) × Density (g/cm³)
For a sheet:
Volume = L (mm) × W (mm) × T (mm) ÷ 1000
For a rod:
Volume = π × (D/2)² × L (mm) ÷ 1000
For a tube:
Volume = π × ((OD/2)² − (ID/2)²) × L (mm) ÷ 1000
Nylon 6 vs Nylon 6/6 — What's the Difference?
Nylon 6 (PA6)
- • Density: 1.14 g/cm³
- • Better impact resistance
- • Easier to process
- • Higher moisture absorption
- • Lower melting point (~220°C)
Nylon 6/6 (PA66)
- • Density: 1.15 g/cm³
- • Higher stiffness and strength
- • Better heat resistance
- • Lower moisture absorption
- • Higher melting point (~265°C)
Note on Glass-Filled Nylon
Glass fiber reinforcement increases density from ~1.14 to ~1.37 g/cm³ at 30% fill — a 20% increase. This significantly affects weight estimates. Always verify the glass fiber percentage with your supplier's datasheet for critical applications.
