What is PC-ABS and Its Density?

PC-ABS is a thermoplastic polymer blend that combines the benefits of both PC and ABS. It is known for its strength, toughness, and resistance to impact. The density of PC-ABS varies based on the specific ratio of PC to ABS, but generally, it ranges from 1.05 to 1.20 g/cm3, making it a lightweight material compared to many other engineering plastics.

Key Benefits of PC-ABS

  1. Lightweight Material: With a density of approximately 1.15 g/cm3, PC-ABS is lighter than many other plastics, which is a significant advantage for applications where weight is a concern.

  2. Transmittance/Optical Nature: While PC-ABS is generally opaque, it retains the glossy surface of ABS and can reflect light well, offering a mirror-like shine when polished.

  3. Heat Resistance: PC-ABS exhibits good thermal resistance, allowing it to function in roles where ABS alone might deflect or burn.

  4. Chemical Resistance: Though not specified for harsh chemical environments, PC-ABS has better resistance to solvents and oxidation than ABS alone.

  5. Toughness and High Impact Strength: PC-ABS is known for its ability to absorb energy and plastically deform without breaking, making it ideal for applications requiring high impact resistance.

  6. Protection from UV Radiation: While not completely resistant to UV degradation, PC-ABS offers better protection than ABS alone.

Mechanical Properties of PC-ABS

The mechanical properties of PC-ABS, influenced by its density and composition, are crucial for engineering applications:

  • Tensile Strength: 5,900 psi/ 41 MPa
  • Tensile Modulus: 278 ksi/ 1.9 GPa
  • Tensile Elongation: 6%
  • Flexural Strength: 9,800 psi/ 68 MPa
  • Flexural Modulus: 280 ksi/ 19 GPa
  • IZOD Impact Notched: 3.7 ft-lb per in / 196 J per m
  • IZOD Impact Un-notched: 9 ft-lb per in/ 481 J per m

Applications and Uses of PC-ABS

PC-ABS, with its balanced properties including density, is used in a variety of applications:

  • Automotive interior components
  • Electronic appliance housings
  • Portable handheld device enclosures
  • Protective casings for electronics
  • Structural components in various industries

Advantages and Disadvantages

Advantages:

  • Heat-treatable to enhance properties.
  • Weldable for assembly and construction.
  • Machinable for complex part fabrication.
  • Durable for heavy-duty use.

Disadvantages:

  • More brittle than some materials at high temperatures.
  • Susceptible to UV degradation.
  • Higher cost due to alloying elements.

Comparison with Other Materials

PC-ABS sits between high-carbon and low-carbon steels, offering a balance of strength and ductility. It also compares favorably with stainless steel in terms of resistance to rust and corrosion.
