Upon his graduation, he was hired by General Electric in Pittsfield, Massachusetts as the new manager of chemical development. It was there in that he invented LEXAN while working on a project to develop new wire insulation material. For the next 35 years, he produced ground breaking research in his field and eventually was the holder of 44 patents. He retired from GE in Junebut continued his polymer research until his death in February Fox's impressive ability to recognize and promote young, talented scientists.
Even though Dr. Fox is often credited with the invention of this plastics product, he was not the first. InFox applied for a patent, two years after his initial discovery of the material. In the same year, Bayer in Germany had also applied for a U. Hermann Schnell that was virtually identical to Fox's. So before it was decided who was to receive the patent, GE and Bayer entered into an agreement that stipulated whoever received the US patent would agree to allow the other to operate by paying a royalty to the patent holder.
This worked out in GE's favor after the patent was awarded to Bayer because Schnell's date of invention preceded Fox's by only one week. From Wikipedia, the free encyclopedia.

Today, it is one of the most well-known brands of polycarbonate sheet. Lexan is a type of polycarbonate PC. It is incredibly tough, and resistant to impacts.
It is also lightweight, when compared to glass. It is used in a variety of applications where materials need to be strong, and virtually unbreakable. It is moldable and comes with a high strength, makes it the ideal industrial plastic for just about anything including food containers, airplane components, automobile manufacturing, construction, golf cart windshields, security windows and doors, window glazing, print materials and so much more.
It is available in a large array of grades, and colors. You can order standard sizes, and same day delivery is guaranteed to some areas. Custom sizes are available and made to order. Lexan is available in Clear, White, Gray and Bronze. Our materials experts will help identify the right solution for your application, put together a quote and a detailed timeline.

Disposable Face Shields Polymershapes has entered into a license agreement with MIT to make available low-cost, mass-produced disposable face shields exclusively for healthcare professionals.Polycarbonates PC are a group of thermoplastic polymers containing carbonate groups in their chemical structures.
Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent. They are easily worked, moldedand thermoformed. Because of these properties, polycarbonates find many applications. Products made from polycarbonate can contain the precursor monomer bisphenol A BPA. Carbonate esters have planar OC OC 2 cores, which confers rigidity. A balance of useful features, including temperature resistance, impact resistance and optical properties, positions polycarbonates between commodity plastics and engineering plastics.
The overall reaction can be written as follows:. The first step of the synthesis involves treatment of bisphenol A with sodium hydroxidewhich deprotonates the hydroxyl groups of the bisphenol A. The di phenoxide Na 2 OC 6 H 4 2 CMe 2 reacts with phosgene to give a chloroformatewhich subsequently is attacked by another phenoxide. The net reaction from the diphenoxide is:. In this way, approximately one billion kilograms of polycarbonate is produced annually.
Many other diols have been tested in place of bisphenol A, e. The cyclohexane is used as a comonomer to suppress crystallisation tendency of the BPA-derived product. Tetrabromobisphenol A is used to enhance fire resistance. Tetramethylcyclobutanediol has been developed as a replacement for BPA.
An alternative route to polycarbonates entails transesterification from BPA and diphenyl carbonate :. The diphenyl carbonate was derived in part from carbon monoxidethis route being greener than the phosgene method. Polycarbonate is a durable material. Although it has high impact-resistance, it has low scratch-resistance. Therefore, a hard coating is applied to polycarbonate eyewear lenses and polycarbonate exterior automotive components.
The characteristics of polycarbonate compare to those of polymethyl methacrylate PMMA, acrylicbut polycarbonate is stronger and will hold up longer to extreme temperature.

Polycarbonate is highly transparent to visible lightwith better light transmission than many kinds of glass. Low molecular mass grades are easier to mold than higher grades, but their strength is lower as a result. The toughest grades have the highest molecular mass, but are much more difficult to process. Unlike most thermoplastics, polycarbonate can undergo large plastic deformations without cracking or breaking. As a result, it can be processed and formed at room temperature using sheet metal techniques, such as bending on a brake.
Even for sharp angle bends with a tight radius, heating may not be necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are needed, which cannot be made from sheet metal. Polycarbonate is mainly used for electronic applications that capitalize on its collective safety features. Being a good electrical insulator and having heat-resistant and flame-retardant properties, it is used in various products associated with electrical and telecommunications hardware.
It can also serve as a dielectric in high-stability capacitors. The second largest consumer of polycarbonates is the construction industry, e. These discs are produced by injection molding polycarbonate into a mold cavity that has on one side a metal stamper containing a negative image of the disc data, while the other mold side is a mirrored surface.
In the automotive industry, injection-molded polycarbonate can produce very smooth surfaces that make it well-suited for sputter deposition or evaporation deposition of aluminium without the need for a base-coat.
Decorative bezels and optical reflectors are commonly made of polycarbonate. Due to its low weight and high impact resistance, polycarbonate is the dominant material for making automotive headlamp lenses.Certain colors are limited to Class II use.
Developed to meet industry flammability codes, LEXAN sheet is widely used in power tools, electrical appliances, communications equipment, business machines, safety equipment and aircraft components. The improved flammability and slightly higher 5 to 10 degrees heat deflection temperature of LEXAN sheet are accompanied by essentially the same physical, electrical, chemical and fabricating properties exhibited by standard LEXAN sheet.
