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

  • • Density: 1.20 g/cm³ (standard grades)
  • • Impact strength: 600–850 J/m
  • • Tensile strength: 55–75 MPa
  • • Service temperature: −40°C to +120°C

Optical & Thermal

  • • Light transmission: up to 90%
  • • UV-resistant grades available
  • • Glass transition: ~147°C
  • • 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.
