What You'll Learn
Polycarbonate is a thermoplastic
Polycarbonate is often used as a replacement for glass. It is naturally transparent, transmitting over 90% of light, but it is also available in opaque varieties. It can be moulded into a wide variety of shapes, including sheets, panels, rods, and tubes. It is used in windows, machine guards, barriers, and bullet-resistant glass. It is also used in eyewear, where its natural UV filter is beneficial.
Polycarbonate is also used in the automotive industry, where its low weight and high impact resistance are advantageous. It is the dominant material for automotive headlamp lenses, and it is used in decorative bezels and optical reflectors. However, it has low scratch resistance and is susceptible to UV degradation, so it requires outer surface coatings in automotive applications.
Polycarbonate is widely used due to its eco-friendly processing and recyclability. It is known for maintaining its colouring and strength over time, even under stressful conditions. It is used in 3D printing, although its high melting point makes it more difficult to work with than some other plastics.
Polycarbonate is also used in medical applications, as it complies with ISO 10993-1 and USP Class VI standards. It can be sterilized using steam, gamma radiation, or the ethylene oxide method. Aliphatic polycarbonates have been developed with improved biocompatibility and degradability for nanomedicine applications.

It is lightweight and strong
Polycarbonate is a lightweight and strong plastic. It is a thermoplastic, meaning it can be melted down and reformed without any major loss of quality. This makes it highly recyclable, which is an important feature in an increasingly environmentally conscious world.
Polycarbonate is 250 times stronger than glass and is highly shatter-resistant. It is also remarkably strong, tough, and impact-resistant. It has a toughness value between -20°C and 140°C, and its high impact strength makes it resistant to fracture. It is so strong that it is used to make bullet-proof glass. Its strength and shatter-resistance make it ideal for security purposes.
Polycarbonate is also very lightweight, which makes it a good substitute for glass. Its lightweight nature increases efficiency and makes the installation process easier. It is also easy to shape and install, especially with the help of a frame or support structure. It can be cut with standard woodworking tools, such as a circular saw or jigsaw. Its low weight and high impact resistance have made it the dominant material for automotive headlamp lenses.
Polycarbonate is a versatile material with a wide range of applications. It is used in the construction industry, for example, for domelights, flat or curved glazing, roofing sheets, and sound walls. It is also used in the automotive industry, for decorative bezels and optical reflectors, and in the medical industry for eyewear, medical devices, and baby feeding bottles. It is used for eye protection and in other projectile-resistant viewing applications that would normally use glass. It is also used for theft-proof packaging for small items, which cannot be opened by hand.

It is used in construction and automotive industries
Polycarbonate is a thermoplastic polymer that is highly impact and shatter-resistant. It is also remarkably strong, durable, and lightweight. These qualities make it ideal for use in the construction and automotive industries.
Construction Industry
Polycarbonate is used in the construction industry to create materials that are durable and light. It is used for domelights, flat or curved glazing, roofing sheets, and sound walls, and cladding. Polycarbonate is also used in greenhouses due to its thermal insulation properties. It can be easily moulded into a variety of shapes and structures, making it a versatile material for construction.
Polycarbonate is also used in 3D FDM printing, producing strong plastic products with a high melting point. It is commonly used for security purposes, such as theft-proof packaging and bullet-resistant glass.
Automotive Industry
In the automotive industry, polycarbonate is commonly used for headlamp lenses, decorative bezels, and optical reflectors due to its low weight and high impact resistance. It can produce very smooth surfaces through injection moulding, making it suitable for aluminium deposition without the need for a base coat.
Polycarbonate is also used for interior components, sunroofs, and windscreens in small motor vehicles such as motorcycles, ATVs, and golf carts. Its lightweight property is advantageous for weight reduction in the automotive industry.

It is recyclable
Polycarbonate is a group of durable thermoplastics that contain carbonate in their chemical structure. It is a transparent plastic that is lightweight, impact-resistant, and shatter-resistant. It is commonly used in various industries, such as construction, automotive, and consumer products, due to its durability and strength.
Polycarbonate plastic is fully recyclable and can be recycled through two major methods: melting and shredding. During the recycling process, polycarbonate is heated until it becomes a liquid and then molded into a new shape. This makes it a sustainable and environmentally friendly material. It can be recycled at certain industry-specific locations or niche recycling centers that work with manufacturers and suppliers.
One of the methods of recycling polycarbonate is chemical recycling, where scrapped polycarbonate is reacted with phenol to produce monomers, which are then purified for further polymerization. Researchers are also working on developing new processes for recycling polycarbonate into another type of plastic that does not release bisphenol A (BPA) into the environment.
The recyclability of polycarbonate makes it an attractive material for both home and industrial uses. It is important to properly recycle polycarbonate to reduce its negative impact on the environment. Some simple practices to recycle polycarbonate include putting unused or damaged polycarbonate in the recycling bin if accepted by local recyclers and reusing it for other applications.
Overall, polycarbonate is a recyclable material that can be reused and repurposed for various applications, contributing to sustainability and environmental responsibility.

It is used in eyewear and medical devices
Polycarbonate is a type of plastic that is used in a wide range of applications, from eyewear to medical devices and beyond. In eyewear, polycarbonate lenses offer excellent vision correction with a thin profile—up to 30% thinner than standard plastic or glass lenses. They are lightweight, durable, and impact-resistant, making them ideal for safety glasses, sports goggles, and children's eyewear. Polycarbonate lenses also provide built-in UV protection and can be customised with various coatings, such as anti-reflective or blue-light-filtering treatments.
In the medical field, polycarbonate plastic is valued for its unique combination of properties. It is lightweight, shatter-resistant, and tough, making it ideal for medical equipment that requires durability and impact resistance. For example, polycarbonate is used in the neonatal unit for incubators, providing a clear and sturdy safety barrier for infants. It is also used in surgical devices, particularly those used in minimally invasive surgeries, due to its ruggedness and ability to be sterilised using various methods.
Polycarbonate is easy to sterilise, which is crucial for medical devices that come into direct contact with patients. It can withstand gamma rays and other sterilisation methods such as steam autoclaving, irradiation, and ethylene oxide (EtO) treatment. This makes polycarbonate ideal for drug delivery devices like nebulisers, dialysis machines, and needle-less safety syringes. Additionally, polycarbonate is heat resistant, ignition resistant, and design flexible, allowing for the creation of thin-walled parts for smaller-scale medical devices.
The optical clarity of polycarbonate is another important feature in medical applications. It offers glass-like clarity, which is critical in clinical and diagnostic settings where visibility of tissues, blood, and other fluids is required. Polycarbonate grades that comply with biocompatibility testing standards, such as ISO 10993-1 and USP Class VI, are available to ensure patient safety.
Polycarbonate's versatility extends beyond eyewear and medical devices. It is used in the automotive industry for headlamp lenses, decorative bezels, and optical reflectors due to its low weight and impact resistance. It is also used for security applications, bullet-resistant glass, and in the construction industry for domelights, glazing, and roofing sheets. With its range of beneficial properties, polycarbonate has become a popular choice for various consumer and commercial products.
