Polycarbonate Grades & Density Values
Polycarbonate (PC) is a high-performance engineering thermoplastic known for exceptional impact strength, optical clarity, and a wide service temperature range. It is roughly 250 times stronger than glass at the same weight.
| Grade | Density (g/cm³) | Density (lb/in³) | Typical Use |
|---|---|---|---|
| Standard PC | 1.20 | 0.043 | Safety glazing, lenses, electronics housings |
| UV-Resistant PC | 1.20 | 0.043 | Outdoor signage, greenhouses, skylights |
| Glass-Filled PC 30% | 1.43 | 0.052 | Structural parts, brackets, high-load components |
Polycarbonate Weight Formula
Weight = Volume × Density
Sheet:
Volume (cm³) = L (mm) × W (mm) × T (mm) ÷ 1000
Rod:
Volume (cm³) = π × (D/2)² × L (mm) ÷ 1000
Tube:
Volume (cm³) = π × ((OD/2)² − (ID/2)²) × L (mm) ÷ 1000
Key Properties of Polycarbonate
Mechanical

- • Flame retardant grades available
Glass-Filled vs Standard PC
Adding 30% glass fiber increases density from 1.20 to 1.43 g/cm³ — a 19% increase in weight for the same volume. Glass-filled grades gain stiffness and dimensional stability at the cost of optical clarity. Always confirm the fill percentage with your material datasheet.
