Polycarbonate Material List


Basic Knowledge of Polycarbonate

What is PC (Polycarbonate)?

Polycarbonate (PC) is a clear and strong material which is part of the polyester family of plastics.  PC is produced through the reaction of bis-phenol A and carbonyl chloride in an interfacial process. It has carbonate groups in their structure. Its durability makes it resistant to breaking, and being lightweight, it's a great substitute for glass.

PC is melted and shaped under pressure to get its desired form. It's popular for its environmentally friendly production and recyclability. PC is transparent and can transmit light with high clarity. It is known for its ability to withstand high levels of impact without shattering. It can withstand a wide range of temperatures because it has good heat resistance, but it can soften at elevated temperatures.

Advantages of PC (Polycarbonate)

  • Lightweight
  • High impact resistance
  • Transparent
  • UV resistant
  • Good electrical insulation
  • Flame retardant
  • Easy to mold and shape
  • Chemical resistance
  • Cost-effective
  • Recyclable

Applications of PC (Polycarbonate)

  • Compact discs (CDs)
  • DVDs (Digital Versatile Discs)
  • Blu-ray discs
  • Eyewear lenses
  • Water bottles
  • Food storage containers
  • Safety goggles
  • Automotive headlamp lenses
  • Laptop and computer housings
  • Cellphone cases


Machining Polycarbonate Buying FAQ

Yes, polycarbonate is generally considered an electrical insulator. It has good dielectric properties, meaning it can resist the flow of electric current.
Polycarbonate is not typically considered bulletproof on its own. While it is a strong and impact-resistant material, true bulletproof properties require specific manufacturing processes and additional layers, such as laminating polycarbonate with other materials like glass or acrylic, to create ballistic-resistant composites.
Yes, polycarbonate can be drilled using conventional drilling methods. It is important to use sharp drill bits and to control the drilling speed to avoid melting or cracking the material. Lubricants or coolants may also be used to dissipate heat generated during drilling.
Polycarbonate is susceptible to degradation when exposed to prolonged sunlight. The material can undergo a process called photodegradation, where UV radiation breaks down the polymer chains, leading to yellowing, loss of strength, and reduced optical clarity. To mitigate this effect, many polycarbonate products are treated with UV-resistant coatings or additives to enhance their weatherability.
