What Is Polycarbonate?


You’ve probably used a product with polycarbonate in it today, even if you don’t realize it. After all, polycarbonate is just about everywhere; it is typically used in eyeglasses, medical devices, auto parts, lighting fixtures, DVDs and Blu-Rays, to name a few. As a naturally transparent amorphous thermoplastic, polycarbonate’s usefulness is in its ability to internally transmit light almost as effectively as glass and to withstand impacts far more significant than many other commonly used plastics. Furthermore, the liability of the material allows it to be created at room temperature without cracking or breaking and to be reformed even without the application of heat. That’s the “amorphous” element. The “thermoplastic” part refers to the nature of polycarbonate and other similar plastics to become liquid at their melting point, which allows, among other things, for easy injection molding and recycling.

Applications of Polycarbonate
Though polycarbonate sheet is prized for its strength and flexibility, its transparency is what allows it to take on a variety of applications that similar materials cannot. As mentioned, the usage of polycarbonate plastic is prevalent in the creation of eyewear; that’s because it’s lighter than glass and possesses a natural UV filter. Listed below are a few more specific applications that display the capabilities of this incredibly versatile material.

Molds for urethane and silicone casting
3D printed models for high heat applications
Machinery guards
LED light pipes and diffusers
Vehicle headlights
Small vehicle windshields
Bullet-resistant “glass.”
Phone and computer cases
Fountain pens
Luggage
What’s more, polycarbonate is as popular in prototypes as it is in finished products. Its durability and transparency make it a perfect stand-in for glass during research and testing.

Types of Polycarbonate
Though polycarbonate sheeting was initially and concurrently developed in the mid-20th century by GE and Bayer, the current plastics marketplace features a variety of developers whom each possess a unique polycarbonate formula and production process. Here are a few details on some of the modern variations and their common uses.

MAKROLON Clear GP Sheet
Designed for glazing and industrial uses, the Clear GP stands alone as the best polycarbonate on the market for protection against vandalism and intentional breakage. This high-impact sheet boasts an impact strength 250 times that of glass and 30 times that of acrylic sheeting, meaning that whatever it’s protecting is going to stay protected. Backed by a five-year warranty against breakage, Clear GP polycarbonate stands head and shoulders above any product in its class.

MAKROLON Clear SL Sheet
Pure light can eventually disintegrate even the sturdiest materials, but that erosion can be slowed dramatically through the protection offered by the enhanced UV resistance of the Clear SL. This material is designed to weather harsh environments and provide an unmatched extension of service life and color-shifting strength. The MAKROLON Clear SL2 provides the same protection on both sides of the sheet for all-around UV resistance.

Polycarbonate Mirror Sheet
This versatile product offers the mirroring of glass with superior impact strength, heat resistance, and both dimensional and UV stability. Ideal for the security and automotive industries, this polycarbonate is the basis for what is commonly referred to as a two-way mirror. It can also be used to create traditional mirrors in high-stress environments, such as in vehicles, retail displays, and institutional bathrooms.

The flexibility of polycarbonate allows for each of these products to be created in a variety of sizes, shapes, colors, and transparencies. All of them provide unmatched strength, functionality, and cost-effectiveness. Follow this link to learn more about the numerous forms of polycarbonate and about the wholesale options available to those who wish to buy this remarkable material in bulk.

Additional Benefits of Polycarbonate
Its durability, transparency, weatherability, and flexibility are but a few of the features that have made polycarbonate a mainstay material across multiple industries. Polycarbonate is also considerably less toxic than many other plastics, and the ease with which it can be recycled only adds to its environmental friendliness. Furthermore, its considerable heat resistance can be enhanced with a variety of flame retardants without significantly lowering any of its other properties. 

No other plastic on the market does as much as well as polycarbonate. Please contact one of our trained plastic experts if you would like to learn more about how one of our quality polycarbonate products can be of use to you and your business.

Oh, there are so many benefits of multiwall polycarbonate sheets that I will start with the one thing that is sometimes seen as a negative. If you look down the end of a layer of polycarbonate it will be like looking down the end of a cardboard box. With the thin wall there is a sheet on the outside, a coating on the inside with a rib running between the 2 sheets. In a cardboard box the slab will be wavy. In multiwall polycarbonate, the rod will be straight between the two layers. Even though the leaves on each side are bright you will not have a clear view due to the distortion from the rib. Inside a greenhouse, you will be able to see a red flower and green leaves, but it will not be bright enough to identify which flower it is. Some people want an unobstructed view like glass, and you don’t get this with these sheets. But, that is the only negative I can think of, so I will go on to the positive.

It is lightweight. A 4′ x 8′ sheet of 8mm twin wall polycarbonate will only weigh about 13 pounds. It is easy to handle. You can bend it onsite (as long as you follow the minimum bending radius chart supplied by the manufacturer) without any tools or special techniques. It applies itself to multiple uses - greenhouses, patio covers, fencing, interior wall partitions, conservatories, skylights, and even hurricane panels. You can cut it quickly with a skill saw, jigsaw or table saw. It is durable. Most manufacturers will have a 10-year hail warranty. And, you won’t see any hail warranty with glass. Compared to drink, it is less expensive. Some people are concerned about the longevity of the polycarbonate sheets. All manufacturers will have at least a 10-year warranty on the light transmission with some now going up to a 20-year warranty. Regardless of the warranty, I consider this to be a material with a 20 year lifetime. The sheets will not get brittle, yellow or crack during this lifetime. There are many different specialty sheets available at this time. There are sheets with 100% light diffusion, 100% block out, heat reducing capabilities, colors such as opal and bronze, etc. Another benefit is that the insulating factor is better than clear glass. This is due to the spacing between the outside sheets. There are also triple wall, 5 wall, 7 wall, etc sheets available. These extra sheets will be sandwich between the two outer layers. This will also cause a higher R-value the more walls and the thicker the polycarbonate is.

Multiwall polycarbonate sheets are versatile, affordable, easy to handle and my choice for greenhouse glazing.

High-Density Polyethylene (HDPE)
When you watch television, use a computer, ride on a bus, train, or plane, you are using plastics. When you go to the doctor’s office or hospital or shop at the grocery store, you again are relying on plastics.

So where do plastics come from … and just what are they?

Plastics are derived from materials found in nature, such as natural gas, oil, coal, minerals, and plants. Nature made the very first plastics—did you know that rubber from a rubber tree is a plastic?

Interest in making plastics arose in the 1800s to replace rare materials such as ivory and tortoiseshell. The first synthetic plastics were derived from cellulose, a substance found in plants and trees. Cellulose was heated with chemicals and resulted in a new substance that was extremely durable.

The raw materials for today’s plastics come from many places (some even use salt!), but most plastics can be made from the hydrocarbons that are readily available in natural gas, oil, and coal.

What are Plastics: the Chemistry
The chemistry of plastics can be difficult, but the basics are straightforward. Think back to your high school science lessons about atoms and molecules (groups of atoms). Synthetics are merely chains of identical molecules joined together. These chains are called polymers. This is why many synthetics begin with “poly,” such as polyethylene, polystyrene, and polypropylene. Polymers often are made of carbon and hydrogen and sometimes oxygen, nitrogen, sulfur, chlorine, fluorine, phosphorous, or silicon.

The term “plastics” or "synthetics" encompass all these various polymers.

Although there are many polymers, plastics, in general, are lightweight with significant degrees of strength. Synthetics can be molded, extruded, cast and blown into seemingly limitless shapes and films or foams or even drawn into fibers for textiles. Many types of coatings, sealants, and glues are plastics, too.
