When it comes to selecting the right plastic for a given application, toughness and impact resistance are key factors to consider. Tough plastics are those that can withstand high-impact forces without breaking, fracturing, or deforming. They are strong, ductile, and able to stretch under pressure. One of the toughest plastics available is polycarbonate (PC), which is more than 20 times stronger than acrylic and 200 times stronger than glass. It is also highly transparent, making it a popular choice for applications that require see-through components, such as windows, roofing, and safety goggles. Other tough plastics include PAI (polyamide-imide), ABS (acrylonitrile butadiene styrene), HDPE, and nylon, each offering unique advantages in terms of strength, durability, temperature resistance, and cost-effectiveness.

Polycarbonate is the toughest plastic, with high impact resistance and strength
Polycarbonate is a high-performance thermoplastic material that is incredibly tough, with excellent impact resistance and strength. It is around 20 times stronger than acrylic and 200 times stronger than glass. It is a versatile and reliable material for both industrial and consumer products requiring high-impact strength and durability.
Polycarbonate is commonly used in applications where high impact resistance and strength are required, such as windows, roofing, signage, helmets, protective goggles, face shields, and food shields. Its strength and impact resistance make it ideal for safety and protective equipment, as well as architectural glazing designed to protect buildings from damage.
Polycarbonate also has a great balance of engineering properties, allowing it to operate in a broad range of temperatures and maintain dimensional stability. This makes it suitable for various environments and applications. Additionally, polycarbonate can be made transparent, with clarity comparable to glass, making it a popular choice for applications that require see-through materials.
While polycarbonate is an excellent choice for its toughness, impact resistance, and strength, it does have some drawbacks. One consideration is that polycarbonate can be prone to scratches. It is also relatively expensive compared to other plastics, which may be a factor in determining its suitability for specific projects.
Other tough plastics with high impact resistance and strength include PAI (polyamide-imide), HDPE (high-density polyethylene), ABS (acrylonitrile butadiene styrene), and PEEK (polyether ether ketone). These plastics are used in various applications where toughness and impact resistance are essential.

PAI is an extremely tough, durable, and stiff plastic with good chemical resistance
Polycarbonate is widely regarded as the toughest plastic available, being twenty times stronger than acrylic and two hundred times stronger than glass. It is also highly transparent, making it a common alternative to glass in applications requiring high impact resistance, such as windows, roofing, safety goggles, and medical devices. However, polycarbonate is prone to scratches and is relatively expensive.
ABS plastic is another popular choice for its affordability and toughness. It is highly impact-resistant, easy to machine, and bonds well with adhesives, paint, and coatings. ABS can be found in various applications, including automotive parts, electronic housings, and children's toys.
While not as widely mentioned as the former options, HDPE plastic is also strong and easy to fabricate. It offers high impact strength, chemical resistance, and low water absorption. HDPE is susceptible to stress cracking under extreme pressure and may experience mold shrinkage during injection molding.
Among the toughest plastics is PAI (polyamide-imide), which is exceptionally durable, strong, and stiff. PAI exhibits good chemical resistance, electrical grade insulation, and low thermal expansion, allowing it to maintain dimensional stability when exposed to high temperatures. Its tensile and compressive strengths enable it to stretch and compress to adjust for high impacts. PAI is also resistant to various fuels, acids, and solvents, making it versatile in manufacturing. However, it is expensive, difficult to process, and can only be used at high temperatures.
In summary, while polycarbonate is often regarded as the toughest plastic, other options like ABS, HDPE, and PAI offer a combination of toughness, durability, chemical resistance, and ease of fabrication, making them suitable for a wide range of applications.

Nylon is wear-resistant, strong, lightweight, and cost-efficient
Nylon is a highly wear-resistant, strong, lightweight, and cost-efficient plastic. Its robustness comes from its high wear and abrasion resistance, allowing it to withstand constant friction and contact with other surfaces without deteriorating quickly.
Nylon's versatility extends further with specialised formulations catering to specific demands. Molybdenum disulphide-filled (MOS2) and oil-filled nylons, for example, offer enhanced wear resistance, eliminating the need for external lubrication. Heat-stabilised nylon can withstand elevated temperatures, often boasting reinforced glass to fortify its strength.
Nylon is also a lightweight plastic, with a low density that makes it significantly lighter than metals such as steel or aluminium. This property is advantageous in various applications, such as automotive components, where weight reduction contributes to improved fuel efficiency.
Nylon's strength and durability make it a preferred material for manufacturing ropes, fishing lines, and industrial components. Its high tensile strength enables it to withstand heavy loads and resist wear and tear. Additionally, nylon possesses fire-retardant properties, enhancing its overall safety and durability.
Nylon is also a cost-efficient plastic. Casting, one of the manufacturing methods for nylon, is often the most cost-effective way to produce large-diameter rods, tubes, and thick sheets. This process allows for the creation of custom near-net shapes, which are useful when constructing parts that would be challenging to make from standard sheets or rods.
