- TECHNICAL DATA SHEET: KEY CHARACTERISTICS AND APPLICATIONS​

Polycarbonate (PC)

General Information:

Product Name: Polycarbonate (PC)

Classification: Amorphous thermoplastic

 

Typical Properties:

  • Density: 1.20 – 1.22 g/cm³
  • Tensile Strength: 55 – 70 MPa
  • Elongation at Break: 50 – 120%
  • Tensile Modulus: 2,200 – 2,400 MPa
  • Vicat Softening Point: 145 – 150°C
  • Notched Izod Impact Strength: 600 – 850 J/m (exceptionally high impact strength)
  • Refractive Index: ~1.586
  • Light Transmission: 88 – 90% (clear grades)
  • Coefficient of Linear Thermal Expansion: 65 – 120 x 10^(-6) K^(-1)
  • Dielectric Constant: 2.9 (at 1 MHz)

 

Features and Benefits:

  • High Impact Strength: PC is known for its virtually unbreakable nature.
  • Optical Clarity: Offers transparency almost equivalent to glass.
  • High Temperature Resistance: Stable in broad temperature range.
  • UV Stability: Can be enhanced with coatings or additives, as raw PC is sensitive to UV radiation.
  • Flame Retardancy: Inherent flame resistance which can be enhanced with additives.
  • Dimensional Stability: Maintains shape and size under stress and heat.

 

Applications:

  • Optics: Eyewear lenses, optical discs, and light covers.
  • Building & Construction: Glazing, roofing, and security windows.
  • Automotive: Headlamp lenses, bumpers, and sunroofs.
  • Electronics: CDs, DVDs, Blu-ray discs.
  • Medical: Medical devices, housings, and drug delivery.
  • General Purpose: Safety helmets, face shields, and riot shields.

 

Processing Methods:

  • Extrusion (sheets, films, and profiles)
  • Injection Molding (components, housings, and high precision parts)
  • Blow Molding (containers and bottles)

 

Environmental Impact and Recycling:

  • PC can be recycled, although it’s essential to separate it from other plastics to maintain its unique properties.
  • When incinerated, PC releases CO₂ and water. However, due to the presence of the carbonate group, it can also release trace amounts of CO.
  • PC recycling is increasing with advances in technology and demand for sustainable materials.

 

Storage and Handling:

  • Store in a cool, dry place away from direct sunlight to avoid potential UV degradation.
  • Handle with care to avoid scratching, as while PC is impact resistant, it can be prone to scratching.

 

Safety Information:

  • PC is safe for various consumer and industrial applications.
  • When processing PC, proper ventilation is essential due to the potential release of bisphenol A (BPA) and other by-products. PC is flammable and should be kept away from open flames; when burned, it can release toxic fumes.

Note: This technical data sheet provides general information and typical values for PC. Actual specifications might differ based on the manufacturer and specific product grade. Always refer to manufacturer-specific data sheets for detailed information on a particular product.
