Tensile Strength

You'll find that ABS has a lower tensile strength than PC, but it's still strong enough to handle most everyday applications. In fact, ABS is particularly attractive in situations where a tough material is needed with high impact strength and rigidity. It can also be combined with other materials to create strong yet lightweight composites.

Even at its lower tensile strength compared to PC, ABS is extremely durable and stands up well against wear and tear. We understand that people take pride in the objects they use every day, which is why we recommend choosing the best material for each application. When you choose ABS or PC for a project, you can rest assured knowing that these materials will withstand everyday use while providing superior performance over time.

Chemical Properties

Discovering the chemical properties of ABS and Polycarbonate can give you an understanding of how materials interact at a molecular level. ABS is a thermoplastic polymer that is formed from three monomers: acrylonitrile, butadiene and styrene. Its chemical composition makes it resistant to many solvents and acids, making it ideal for applications where strength and durability are important.

Polycarbonate, or PC, on the other hand, is a transparent amorphous thermoplastic that gets its superior strength from the strong bonds between molecules in its polymeric structure. It has excellent impact resistance and optical clarity, making it suitable for use in safety glasses and lenses, as well as being used as a structural component in products like computer cases or automobile parts.

Both materials share similar characteristics when it comes to chemical properties such as temperature resistance, but their differences lie in their physical properties such as tensile strength or heat transferability. Understanding these distinctions can help you make an informed decision about which material best suits your needs.

Temperature Resistance

Surprisingly, ABS and Polycarbonate may not be as different as you'd think when it comes to temperature resistance - both materials can handle extreme heat and cold without breaking a sweat!

When it comes to hot temperatures, both materials are capable of withstanding up to 100°C before buckling or deforming. This makes them ideal for applications such as electrical enclosures and automotive parts.

• ABS:
  • Is lightweight and low cost, making it ideal for mass production.
