Polycarbonate

This material is used frequently for shields, guards, and containment barriers. Can be cold or heat bent to most configurations. A popular material manufacturer 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®, 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 Plaskolite (formerly Covestro), SABIC and Plazit Polygal. All three have extrusion equipment in the USA and produce high clarity Polycarbonate sheet. Some of the leaders in the Thick Plate and Rod extrusion are Ensinger, Polymer, Westlake and Gehr Plastics.

The different version of the Polycarbonate resin cover a wide range of manufacturing machinery,ie: Injection Molding, Extrusion, Blow molding, etc. In addition, there are different Polycarbonate grades based on the application where the material will be used.

Basics

Why you should use Polycarbonate:

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:

1) Plaskolite (formerly Covestro Plastic) produce Tuffak® Polycarbonate (formerly Makrolon®) sheets as well as a full line of Acrylic Sheet and Acrylic Mirror materials. 

2) SABIC (Saudi Arabia Basic Industries Corporation) Plastic, producing a wide range of plastic resins including: Lexan® Polycarbonate, Cycolac®, ABS, Noryl®- Poly Phenylene Oxide (PPO), Ultem® 1000 and Ultem® 2300 PEI resins.

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.

Applications

Machine Grade ABS compares favorable with other engineering and mechanical plastics.

Because ABS is bondable, it is frequently used to replace machinable plastics that are not bondable, like Nylon, Acetal and HDPE. ABS is paintable, sandable, and is machinable with standard shop equipment.

Question:

How does ABS compare with Acetal and other materials?

Answer:

It is a strong rigid plastic material that machines well, with a high impact strength. It is as dimensionally stable as more expensive plastics and is FDA compliant for food contact and yet is still bondable and paintable.
