Key features

  1. Amorphous/Semi-Crystalline - PC-ABS is a type of thermoplastic that is composed of acrylonitrile-butadiene-styrene (ABS) and polycarbonate (PC). It is a blend of amorphous and semi-crystalline polymers, which gives it a balance of properties, such as strength, flexibility, heat resistance, and surface finish.
  2. Chemical Resistance - PC-ABS has excellent chemical resistance and is highly resistant to hydrocarbons, oils, and greases. It also has good resistance to bases, acids, and salt solutions.
  3. Impact Resistance - PC-ABS is highly impact-resistant, making it ideal for applications that require durability and toughness. It also has excellent thermal stability and chemical resistance.
  4. Molding Process - PC-ABS can be molded using various methods, including injection molding, blow molding, and compression molding. It is also capable of being extruded, thermoformed, and machined.
  5. Processing Temperature - PC-ABS has a wide processing temperature range, from -20°C to +80°C. It is also able to withstand higher temperatures for short periods of time without losing its properties.
  6. UV Resistance - PC-ABS has excellent UV resistance and can be used outdoors without discoloring or degrading over time.

Important considerations

Pros

  • Weather-resistant: PC-ABS is highly resistant to weathering, meaning it can stand up to exposure to the elements without corroding or degrading over time.
  • Cost-effective: PC-ABS is a relatively cost-effective material, making it a great choice for projects where cost-efficiency is important.
  • Lightweight: PC-ABS is a lightweight material, which makes it ideal for applications where weight is a factor.
  • Flexible: PC-ABS is flexible, making it suitable for applications where the material needs to be able to absorb and dissipate energy.
  • Durable: PC-ABS is a very durable material, making it perfect for applications that require long-lasting materials.
  • Heat Resistant: PC-ABS is heat resistant, making it suitable for applications that require materials that can withstand high temperatures.

Cons

  • Moisture Sensitivity: PC-ABS is moisture sensitive and can absorb moisture from its environment, which can lead to swelling and deformation.
  • High Temperature Impact Resistance: PC-ABS is not as impact resistant as some other plastic materials when exposed to high temperatures.
  • Extrusion and Printing: PC-ABS is harder to extrude and print than other thermoplastics. It requires higher levels of heat and pressure, making it more difficult and time consuming to fabricate.
  • Cost: PC-ABS can be more expensive than other materials, meaning the cost to fabricate parts can be a concern for potential buyers.
  • Smell: When heated, PC-ABS can emit an unpleasant smell which can be a problem in close working environments.

Trivia

PC-ABS is a unique blend of polycarbonate and acrylonitrile-butadiene-styrene (ABS) materials, which offers increased toughness and heat resistance compared to ABS alone. It is also lightweight, making it an ideal choice for 3D printing. Interestingly, PC-ABS was also used in the original Star Trek movie, where it was used to make the communicator badge worn by Captain Kirk. This was due to the material's unique combination of properties, including strength, temperature resistance, and flexibility. PC-ABS has also become the material of choice for the 3D printing of cosplay props, such as helmets and armor, due to its strength and durability. Source: Matterhackers
