ABS is a thermoplastic polymer with excellent durability, rigidity, and scratch resistance
Acrylonitrile Butadiene Styrene (ABS) is a widely used thermoplastic polymer known for its versatility, durability, and ease of processing. It is one of the most affordable thermoplastics and offers excellent mechanical properties, including high stiffness, impact resistance, and toughness. ABS is stable under normal use and polymer processing conditions, and its ability to withstand loads and stresses makes it suitable for structural components.
ABS is created by polymerizing styrene and acrylonitrile in the presence of polybutadiene. This process forms chemical "chains" that bind together, giving ABS its superior hardness, gloss, toughness, and resistance properties. The ratio of these monomers can be adjusted to obtain different grades of ABS with varying strengths, rigidities, and impact resistances. For instance, increasing the proportion of polybutadiene in relation to styrene and acrylonitrile enhances impact resistance, while higher amounts of acrylonitrile result in increased strength.
ABS has a wide range of applications across various industries, including automotive parts, consumer goods, electronics, and toys. Its impact resistance, versatility, and electrical insulation properties make it ideal for these applications. In the automotive industry, ABS is used for both interior and exterior components, such as dashboards, door panels, and mirror housings.

ABS is highly resistant to many chemicals, but susceptible to concentrated acids and UV rays
ABS, or Acrylonitrile Butadiene Styrene, is a popular thermoplastic with a broad range of applications. It is used in industries such as aerospace, medical, automotive, oil and gas, and food handling. It is also commonly used in consumer goods, electronics, appliances, and construction materials.
ABS is known for its excellent durability and rigidity, making it highly resistant to scratches and warping. It is also one of the most affordable thermoplastics available. ABS is a versatile material that can be easily machined and fabricated, making it a popular choice for 3D printing.
While ABS has many desirable properties, it is important to note that it is susceptible to degradation when exposed to certain conditions. One of its major drawbacks is its susceptibility to UV rays and sunlight. Prolonged exposure to UV radiation or sunlight can cause ABS to degrade, discolour, or fade. This was evident in one of the most widespread and expensive automobile recalls in US history, where degradation of the seatbelt release buttons occurred due to UV exposure.
Additionally, ABS is highly resistant to many chemicals but is susceptible to concentrated acids. It can withstand exposure to many common household and industrial chemicals, including acids, alkalis, and various solvents. However, it may experience degradation or swelling when exposed to certain harsh chemicals, such as concentrated sulfuric and nitric acids, ketones, and hydrocarbons.
To enhance the UV resistance of ABS, UV stabilizers or coatings can be incorporated into the mix. Similarly, the flammability of ABS can be reduced by adding flame retardant additives.

Polycarbonate is naturally UV-resistant and commonly used outdoors, but can be affected by prolonged exposure
Polycarbonate is a popular choice for roofing in both commercial and residential construction due to its natural UV-resistant properties. It blocks almost the entire UV spectrum, including UVA and UVB rays, providing protection from the harmful effects of UV radiation. This makes it ideal for outdoor use, such as in swimming pool roofing, where it allows natural light transmission while blocking harmful UV rays.
Polycarbonate's UV resistance is due to its ability to absorb UV radiation. However, this absorption can lead to the material's deterioration over time. The polycarbonate sheets may become yellowed or discolored, and their structural integrity may weaken, eventually causing them to break. Therefore, while polycarbonate is naturally UV-resistant, it can be affected by prolonged UV exposure.
To address this issue, manufacturers apply protective coatings or layers to the polycarbonate sheets. These coatings are designed to be very thin and invisible, preserving the optical characteristics of the material while providing additional UV protection. This added protection ensures that the polycarbonate sheets maintain their benefits and durability over an extended period.
It is important to note that the UV protection offered by polycarbonate is intended to safeguard the material itself rather than individuals or objects beneath it. The absorption of UV radiation by polycarbonate can still result in the material's discoloration or loss of properties over time. Therefore, while polycarbonate is inherently UV-resistant, additional measures are necessary to enhance its longevity in outdoor applications.
When compared to other plastics, such as ABS (acrylonitrile butadiene styrene), polycarbonate stands out for its toughness and strength. ABS is a durable and rigid thermoplastic polymer with excellent "machinability" and heat-deflection capabilities. However, it may require adjustments in the ratio of its monomers to achieve specific properties, such as strength or rigidity. Polycarbonate, on the other hand, is known for its superior impact resistance and high-temperature performance, making it a preferred choice in applications where these characteristics are crucial.
