Polycarbonate finds extensive applications in automotive, construction, electronics, and healthcare sectors due to these remarkable properties.
What is ABS?
ABS or Acrylonitrile Butadiene Styrene is a powerful thermoplastic polymer that is extremely strong, durable and versatile. It is comprised of three monomers—acrylonitrile, butadiene, and styrene. Each monomer possesses certain traits that contribute toward the overall material.
Acrylonitrile
Provides chemical resistance and heat stability
Butadiene
Gives toughness and impact resistance
Styrene
Adds rigidity and a smoothly finished surface
ABS is a lightweight, cost-efficient, and easy-to-process polymer that is favored in many different industries. It has found its way into the production of various automotive parts, electronic enclosures, consumer goods, and toys, with Lego bricks being a famous example. In addition to this, ABS can be recycled extensively and reshaped through heating, thus facilitating eco-friendly practices in industrial applications.
Overview of PC-ABS Blends
PC-ABS (Polycarbonate-Acrylonitrile Butadiene Styrene) composites marry the impact resistance and heat resistance of polycarbonate (PC) with the easy processing and cheaper price of ABS. This mixed material is used for its extraordinary mechanical properties (toughness and high heat resistance) and is consequently a preferred material in the most stringent application areas.
Why Use PC-ABS Blends Instead of Pure Materials?
The blend improves dimensional stability and surface finish offering both functional and aesthetic benefits. By fusing the two, manufacturers are able to possess a balanced, high-performing material that increases product longevity while optimizing production costs.
Properties of Polycarbonate and ABS
Mechanical Properties of Polycarbonate
Polycarbonate (PC) is a well-known material in many sectors due to its great mechanical properties. Here are the most important characteristics:
| Property | Value | Significance |
|---|---|---|
| Impact Strength | > 10 kJ/m² | Perfect for safety applications like protective helmets |

Comparing ABS and Polycarbonate Properties
A side-by-side comparison of ABS (Acrylonitrile Butadiene Styrene) and polycarbonate reveals two materials with unique properties and advantages that correspond to different applications.
Material Selection Insight: Recent reports show that although the cost-effective and easy-to-machine nature of ABS is still very much its selling point, polycarbonate is always the first choice when transparency and high mechanical strength are paramount factors. These distinctions point to the necessity of material selection based on the specific needs of the application.
Impact Resistance and UV Protection
Impact Resistance of Polycarbonate
Polycarbonate Impact Strength
250x
Stronger than normal glass
Polycarbonate has the reputation of being the thermoplastic with the highest impact resistance; thus, it is one of the most durable plastics available. Evidence shows that polycarbonate possesses impact strength that is around 250 times greater than that of normal glass and much stronger than a number of plastics, like acrylic, for example.
Why Polycarbonate Has Superior Impact Resistance:
- Absorbs and disperses energy without cracking or breaking
- Impact resistance remains effective in extreme temperature variations
- Reliable in both very cold and hot conditions
- Ideal for high-stress applications requiring strong material performance
Common Applications Requiring High Impact Resistance:

- Bulletproof Glass: Security applications in banks and vehicles
- Protective Equipment: Industrial safety gear and shields
- Electronic Device Casings: Smartphones, tablets, and laptops
UV Stability of ABS vs Polycarbonate
When examining the UV stability of ABS (Acrylonitrile Butadiene Styrene) and polycarbonate, it is clear that polycarbonate has a better ability to resist UV degradation.
Research Findings: Current investigations revealed that UV-protected modified polycarbonate materials could maintain clarity and reinforcement for years even when exposed to direct sun, however, non-treated ABS would need added UV protection to survive the same conditions. Moreover, while both materials can be modified for outdoor applications, polycarbonate generally, in its natural or improved form, guarantees that it will last longer and will be more resistant to the effects of UV light.
Applications Benefiting from Impact Resistance
Among the various materials that offer impact resistance, polycarbonate and ABS are the main ones that industries benefit from in the most diverse applications. Their shock and physical force resistance gives them the place in the list of materials that are fit for demanding environments.
🚗 Automotive Industry

🏗️ Construction Field
Glass, plastic sheets, and fences to protect workers and provide structural integrity
📱 Electronics Manufacturing
Casings for appliances and devices to keep internal parts secure from drops and impacts
💻 Portable Devices
Smartphones and tablets benefit from robust shield against accidental drops and impacts
This trend of wider application is indicative of the escalating need for dependable materials in both consumer and industrial markets, which helps to secure prolonged usage and high performance across various fields.
Tensile Strength and Chemical Resistance
Tensile Strength Comparison: ABS vs Polycarbonate
ABS (Acrylonitrile Butadiene Styrene) and polycarbonate are two of the most commonly used materials, mainly because of their excellent properties such as strength and durability. In the case of tensile strength comparisons, polycarbonate nearly always wins over ABS.
Tensile Strength Comparison
Polycarbonate
