Polycarbonate sheet material is used frequently for shields, guards, and containment barriers.
It can be cold or heat bent to most configurations. A popular material manufactured by several companies: Lexan® by SABIC, Tuffak® by Plaskolite (formerly Makrolon® by Covestro), Zelux® by Westlake, Unicar® by Nytef Div of Polymer, Ensicar® by Ensinger, Cyrolon®, Polygal®, Plazit®, Tuffak® GP, Paltuf®, Texin®.
Today, there are numerous versions of these Polycarbonate resins, produced by a dozen different resin manufacturers; however Lexan® and Makrolon® still lead the field.
In addition to the large number of resin manufacturers, there are also dozens of extruders that can produce the Polycarbonate in Sheet or rod.
The leaders are Tuffak Plaskolite (formerly Covestro), SABIC Lexan and Plazit Polygal. All three have extrusion equipment in the USA and produce high clarity and high quality Polycarbonate sheet.
Some of the leaders in the Thick Plate and Rod extrusion are Ensinger, Westlake, Rochling, Polymer and Gehr Plastics.
Polycarbonate sheet is a common material for a variety of glazing applications, impact resistant shields and formed parts. Polycarbonate Sheet and Rod are generally produced from plastic resin produced by two main plastic resin manufacturers:
The general purpose Polycarbonate resins are about the same as they were when they were first invented. The research on this resin started in 1898, but was first perfected by Bayer in Germany and was patented and registered in 1955. Amazingly, one week after the first invention by Bayer, Daniel Fox at General Electric in New York, independently synthesized a branched Polycarbonate resin.
Both companies filed for US Patents in 1955, and agreed that the company lacking priority would be granted a license to the technology. The patent was resolved in Bayer’s favor and Bayer began commercial production under the trade name Makrolon® in 1958.
GE Plastics began production under the Lexan® trade in 1960.
Polycarbonate is ITAR compliant, and Polycarbonate is RoHS compliant.

Plastics have been around for over a century now, and are used in almost every industry and application. The problem is that society has made the plastics industry the poster child for waste, trash and pollution. This is unfair, and factually incorrect.
Plastic materials are lighter, cost less to produce, use less electrical power to produce, and are safer for use. It is not new phenomenon that a material or product, once used, gets thrown away. This is the normal life cycle of many materials. Some inexpensive plastic materials used in consumer goods are made to throw away once the item has been purchased. Things like the indestructible packing we fight on kids toys, the cheap plastic sporks from restaurants, the prolific plastic water bottles and of course, the plastic grocery bags. All of these materials are 100% recyclable, the hitch is that it requires a little effort to recycle.
Are Plastic Materials The Cause?
On the positive side, the products that plastic currently replaces are much larger, heavier and generally cost more to produce, and use more energy to produce. This means, that the large amount of plastics that are not being properly disposed of, are replacing much larger quantities of materials that would not be recycled. I still remember times when I was a kid, and seeing tin cans in the lakes and rivers when out fishing. People polluting with their trash is not a new thing, now it is just a different group of materials.
Thermoplastic plastic materials are recyclable, and can be used over and over again. Generally, the recycled product would not be for a Food or Medical application. A common use of recycled plastic is with the collected milk jugs and detergent bottles, both HDPE, can be ground and turned into plastic lumber. The plastic lumber can be used to replace standard wood products for decks and outdoor furniture, and it will last for 15 – 20 years with no maintenance or painting. The cost savings and reduced use of natural resources for this one product can be staggering. The color doesn’t fade, it wood won’t split or crack, and it continues to look good for up to two decades.
Our recent article, “Plastic Material Bad Reputation – How did we get here?“, we discuss the factors that have lead to the ‘throw away’ society that we have become. Much of this bad reputation is for products that are designed as one use and then designed to be thrown away. So, if we are to change the bad reputation, companies need to change this design flaw, and start using materials for applications that can be reused easily.
If we can minimize the use of throw away plastics, and recycle the plastic material once we are done with it, we can help to limit plastic in land fills.
The blame for plastic pollution should be placed…on people. The plastic is not the cause of the problem, it is the litter-bug and irresponsible individuals that trash our planet. How do the plastic bottles and grocery bags end up in the ocean. They certainly don’t throw themselves in to the ocean, it is lack of responsibility and negligent behavior.
It really only takes a couple of seconds to throw something into a recycle bin. Even better would be to reuse the plastic bottles or plastic bags. Plastic materials are not the problem, empathetic people are the problem.
