Today we&#;ll see some of the most exciting facts about polycarbonate plastic. If you&#;re a new user or thinking of buying a polycarbonate sheet for the first time, you&#;ll find these facts very useful.

So without further delay, let&#;s jump into the real thing.

Fact #1

You already know polycarbonate is a very strong and robust material. But did you know how strong it is compared to glass or plexiglass sheets?

This plastic material is 30 times stronger than acrylic and over 180-200 times stronger than glass material.

Fact #2

Dr. Hermann Schnell is considered to be the inventor of Polycarbonate resin. He invented it back in .

Fact #3

Although this one is superior in strength from other materials such as glass, it is significantly lighter. The material is lighter than glass or most plastics.

The lightweight nature makes it an even more excellent choice among buyers. And they&#;re easy to install as well.

Fact #4

The wide range of applications of PC plastic is genuinely impressive. From aerospace and bulletproof windows to sunglass lenses, they&#;re used everywhere.

They are mostly used for windows, roofing panels, the aerospace industry, automotive parts, bulletproof windows, riot shields, skylights, bubble tents, office chair mats, or other projects where you need transparent and strong plastic sheets.

Fact #5

Polycarbonate offers natural UV protection from the harmful UV rays, making it an even greater choice for the home roofing panel and greenhouses.

Fact #6

Polycarbonate was originally developed for astronauts to use on the outer visors. The plastic and gold layer protects astronauts from harmful rays and radiation.

Later because of the exceptionally well reputation and durability, PC sheets became a household item for many applications.

Fact #7

This robust material can be easily formed and shaped without the risk or breaking or chipping, despite its extreme strength.

Fact #8

Polycarbonate is a safe material with no toxic releasing or exposed to the flames. You can use them for any applications including items for infants or tiffin boxes.

Fact #9

This plastic is approved by the food and drug administration. People use them for food applications like food trays, bowls or spoons. Especially in hospitals, you&#;ll find the most use of them.

Fact #10

Most of the dome lights, skylights and sound walls you see in the buildings are made of polycarbonate plastic.

Fact #11

This is entirely fire-resistant material, and also prone to flames. Because of this, they&#;re commonly used for electrical components due to safety and security. Also, the transparency and lightweight nature of polycarbonate is another reason for this to be used in this application.

Fact #12

The reason why this plastic material is widely used for automotive car parts is not only because of its strength. The main reason is the lightweight nature of polycarbonate material.

Automotive manufacturers always look for lighter materials to increase the performance of their vehicles. And while polycarbonate is excellent because of the other features, it&#;s also lightweight, making it a perfect choice for manufacturers. They need non-glare polycarbonate, ESD polycarbonate.

Polycarbonate is an extremely versatile type of plastic that can be used in a wide variety of applications. More specifically, in terms of composition, polycarbonates are a group of thermoplastic polymers that contain carbonate groups within their chemical structures. Polycarbonate is a strong material, yet because it's comparatively lightweight, it's straightforward to transport and install. Naturally transparent, polycarbonate is also available in a range of colours. It is easily worked, moulded, and thermoformed.

The history of Polycarbonate

Polycarbonates were first discovered in by Alfred Einhom, a German scientist working at the University of Munich, however after 30 years' laboratory research, this class of materials was abandoned without commercialization. Researched resumed in , when Hermann Schnell at Bayer in Germany patented the first linear polycarbonate and subsequently the brand name "Makrolon" was registered later in . Up until Polycarbonate was produced with a brownish tint, however after significant improvements in the manufacturing process it became possible to produce glass-clear polycarbonate which led to far greater commercial demand for the material. 

The properties of Polycarbonate

Polycarbonate's many positive properties are the reason why it's so often chosen over other forms of plastic sheeting. First and foremost, polycarbonate is tough and highly resistant to impact. Polycarbonate is up to 200 times stronger than glass, and is considered to be almost unbreakable, which makes it a much safer and more secure option for high-traffic areas. It is also particularly suitable in both commercial and residential glazing applications. In addition, polycarbonate&#;s durability translates into excellent longevity, which in turn makes it a great long-term investment.

Lightweight and malleable

Despite its strength, polycarbonate is lightweight, so it's cost-effective to ship, easy to handle, and needs less support than heavier alternatives to hold it in place. These properties illustrate why polycarbonate is an excellent option for greenhouses, secondary glazing and a variety of other glazing applications.

Another big positive of polycarbonate is that it's one of the easiest types of plastic sheet to process &#; unlike many other plastics, polycarbonate can be easily cut, drilled, and formed without cracking or breaking. It can be shaped or bent at room temperature, however typically in a commercial environment it would be cold formed/bent and then heated to ensure that the material doesn't spring back to its original form. These properties make Polycarbonate suitable for a wide variety of fabrication processes and applications.

Clarity and insulation

Polycarbonate offers superb long-lasting clarity and excellent light transmission that's comparable to traditional glass. However, while it lets the light through, it keeps the elements out. That's because polycarbonate is an effective thermal insulator. It retains more heat than both traditional glass and its acrylic counterpart &#; a quality that makes it particularly suited for use within secondary glazing, home extensions and conservatories.

Polycarbonate's K- and U-values are a useful indication of its insulation properties. A material's U-value measures heat loss through a given thickness of a building, roof, wall or floor. In general terms, the lower the U-value, the better the material in question is as a heat insulator. A material's K-value refers to its ability to conduct heat. A low K-value is advantageous for insulating materials, as this means heat energy cannot easily pass through. As the table below illustrates, polycarbonate out-performs glass in both regards. Traditional single pane glass has an average K value of 0.96 whereas our Polycarbonate sheets have a K value of 0.21 which demonstrates why Polycarbonate provides superior insulation to traditional glass, in addition to being cheaper and easier to install and maintain.

UV and fire resistance

Yet another advantageous property of polycarbonate is its UV-resistance. In addition to withstanding all sorts of harsh weather &#; even snow and heavy rain &#; polycarbonate filters out a large proportion of harmful UV rays that glass allows through. This is good news for greenhouses, as it prevents plants from UV damage. Like most UV polycarbonate material, our Palsun Solid Polycarbonate Sheets are UV-protected on one side, which significantly improves long-term weatherability. A comparison of the UV protection offered by PALSUN and that offered by sunscreen cream 15 is depicted in the graph below.

100% recyclable

In contrast to single-use plastics which contribute significantly to plastic waste, our Palsun Polycarbonate portfolio is 100% recyclable, to help create a more sustainable environment. Furthermore, each sheet contains up to 30% recycled content.

What can polycarbonate be used for?

The multipurpose properties of polycarbonate mean it is a highly versatile material that can be used in many different ways. It's most commonly used for roofing and glazing (both primary and secondary), and especially for greenhouses, conservatories and orangeries. More recently, during the COVID epidemic, polycarbonate was also used for sneeze screens and safety guards. Other typical applications include:

• Sky lights
• Construction
• Automotive and aircraft components
• Security components
• Signage
• Vending machines
• Street furniture
• Machine guards
• Lighting 
• Roof domes
• Bicycle racks

The different types of polycarbonate

We offer four main types of polycarbonate &#; solid sheet, prismatic, multi-wall/twin-wall and Georgian wire.

As its name suggests, solid clear polycarbonate sheet looks just like glass but, is stronger and lighter. It offers 89% light transmission and is available in a range of thicknesses, from 1mm to 12mm. We also stock Opal Polycarbonate which is available in 2mm, 3mm and 5mm gauges.  The maximum sheet size available is mm x mm.

Prismatic polycarbonate sheet incorporates a textured pattern on one side, which is optimised for both light transmission and diffusion, making it a popular choice for lighting applications. Its aesthetic appeal also works well within interior and exterior decoration, and exhibition displays. The maximum sheet size is mm x mm and it is available in a 3mm thickness.

Multi-wall polycarbonate sheet features multiple layers which form a honeycomb-like structure. It offers superb thermal insulation (and relatively good sound insulation), making it a popular choice for conservatories, greenhouses, carports, and lean-to extensions. Twin-wall polycarbonate is similar to multi-wall, except it has just two layers instead of several. It is a popular choice for smaller projects such as cold frames and cloches. Both products are available in clear, opal and bronze.

Frequently asked Questions

- What is the lifespan of Polycarbonate?
With proper care, polycarbonate should last at least a decade. The polycarbonate we supply is guaranteed against discolouration for 10 years.

- Which is better: polycarbonate or acrylic?
It depends on the intended usage. These materials share many similar properties. Polycarbonate is much stronger and more flexible than acrylic &#; but it's usually more expensive. In terms of appearance, acrylic is glossier and marginally more transparent. Polycarbonate also scratches easier than acrylic.

- What is the best thickness for polycarbonate?
Again, it all depends on the intended application. For example, thicker sheets (25mm, 32mm and 35mm) of twin/multi wall are the best option for external roofing applications. For greenhouses, cold frames and secondary glazing thicknesses of 3mm, 4mm and 5mm are the most popular choices.

- Does polycarbonate discolour?
Because they are resistant to temperature extremes and UV light, polycarbonate panels should not fade or discolour for many years. Cheaper versions may yellow over time.

- How do you clean polycarbonate?
Polycarbonate should be cleaned gently, with warm water, a few drops of liquid detergent, and a microfibre cloth.

- What are the disadvantages of polycarbonate?
There really aren&#;t many! It can scratch if it isn&#;t handled carefully, and it can&#;t be laser cut.
