• Engineering Films
  Specific properties that separate engineering films from their commodity counterparts include greater tensile and impact strength; improved moisture and gas barrier characteristics; good heat resistance and weatherability; better bonding and lamination; and improved electrical ratings. One or more...
• Thermally conductive polymers delete the heat
  degrade the polymer and lead to part failure. But the addition of nonmetallic fillers in commodity and engineering thermoplastics such as ABS, nylon, liquid-crystal polymers (LCP), and polyetheretherketone (PEEK) makes uniform heat dissipation possible. Parts made from the CoolPoly polymers are also 40...
• The Science Behind Triboplastic Bearings
  During my recent travels, I revisited a customer who, just a few years before, was set against using plastic bearings. He knew he could save a lot of money by making the switch, but couldn't be convinced that plastic-a material that most people equate with a disposable commodity like a plastic fork...
• Plastics that perform
  A basic understanding of material properties and processing options will help pinpoint the right polymer for complex plastic parts. The uninitiated may find the expanding volume of data for engineered plastics challenging to sort through and a bit confusing. The pressure put on plastic suppliers...
• MICRO:The 300-mm Imperative, by Gary Gallagher, p.81 (July '99)
  another carrier, technical commodity, or big wafer "boat." It is a very sophisticated extension of existing fab equipment that must adhere to exact specifications and be functional, reliable, and dimensionally accurate enough to interface time and time again with some of the industry's most precise...
• UV Properties of Plastics: Transmission and Resistance (.pdf)
  . All types of UV can cause a photochemical effect within the polymer structure, which can be. either a benefit or lead to degradation of some sort to the material. Note that compared to our. skin, the higher energy UVC is more likely to affect plastics. Degradation. The main visible effects...
• Kerk Motion Producs Help Waters Corp. Make Large Splash with Small UPLC Unit (.pdf)
  to the UPLC concept. "We considered several vendors, but Kerk had the best set of performance data," said Plant. "While other vendors were selling off the shelf commodity items, Kerk's products allowed for. customization and flexibility to react to customer needs. We were impressed that Kerk was willing...
• New Ways To Clean Up Water and Use It Again
  treatment site and cultured them in the lab. Then they encapsulated the bacteria in polymer gels and verified their denitrification rates. They called the final product "immobilized denitrification sludge," or IDS. Hunt and Stone then devised a bioreactor by placing the IDS into a small reactor...
• Feathers Can Be for More Than Pillow Stuffin'
  in Beltsville, Maryland, polymer chemist Masud Huda (background), chemist Walter Schmidt (center), and Marc Teffeau, director of research for the Washington, D.C.-based Horticultural Research Institute, produce biodegradable flowerpots from chicken feathers. (D1503-21). Chicken Processing Industry...
• MICRO:Product Technology News (April '2000)
  . A static-dissipative polypropylene alloy for use in semiconductor-handling and other cleanroom applications offers a consistent surface resistance of 108 . Stat-Rite S-250 is based on a patented inherently dissipative polymer system that remains intact from the polymerization stage through compounding...
