MATERIALS:Bayer MaterialScience LLC has developed a grade of polycarbonate resin that allows for up to 92.3 percent efficiency in a 30 mm diameter optic lens. The new Makrolon®LED2643 polycarbonate is also expected to soon meet the latest UL 8750 standards for LED lighting (UL-94 V-2 rating).
Bayer MaterialScience collaborated with a team at Carclo Technical Plastics to develop a grade of polycarbonate resin that would meet the requirements of a new Carclo 30 mm diameter optic. The optic’s large size — larger than the typical lenses Carclo manufactures, which have diameters of 20 or 26.5 mm — is necessary in order to efficiently collimate all the light from large diameter LED light sources. With this in mind, Bayer MaterialScience formulated a very low-loss material because all optics, and especially optics this large, naturally absorb some light due to their mass.
Makrolon LED2643, a robust, molder-friendly material, is the latest addition to Bayer MaterialScience’s extensive portfolio of polycarbonate resins for the burgeoning LED market. The polycarbonate is UL listed, as well as achieving an f1 rating, making it suitable for many wet outdoor applications.
This tough, impact-resistant material exhibits excellent weatherability, elevated heat resistance and high light transmittance. Makrolon LED2643 also has a high molecular weight, which translates into improved productivity for molders.

For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
