• The weak link in reinforced nylons
  at excessively high melt temperatures exhibit what is called "fountain flow." Here, the additive doesn't reach the frozen wall layer directly and instead flows first down the center of the mold cavity to the melt front. This can alter flow direction and orientation of polymer molecules and fibers...

• Plastic Diode Could Lead To Flexible, Low Power Computer Circuits, Memory
  Previous stories pertaining to Professor Berger's research: "Sensor Could Detect Concealed Weapons Without X-Rays," "New Diode Could Enable Faster, More Efficient Electronics, COLUMBUS, Ohio - Ohio State University researchers have invented a new organic polymer tunnel diode - an electronic...
• Healing by Design
  arthroscopically, Derwin’s approach, or a similar polymer patch, would be unlikely to catch on among surgeons. Without a net. Some tissues have demonstrated that they don’t need a scaffold at all. The University of Michigan’s Artificial Heart Lab put rat heart cells in growth media on a protein-rich...
• Gas-Assist Molding: Not just for hollow parts
  such as blow or rotational molding have a tough time with it as well. The gas-assist process improves polymer fill or packing and boosts the melt flow length. This lets designers mold larger, more complex parts with fewer injection gates and may help eliminate the need for complicated runner systems...
• Medical Device Link .
  Carbon Fiber Reinforced Polymer Specified for Prosthetic Device Other materials could not support weight loads. In developing the Total Concept adjustable-heel-height articulated ankle, Century XXII Innovations Inc. (Jackson, MI), a manufacturer of prosthetic limbs, experienced difficulties...
• No stress nylon
  .-diameter cavity in the steel casting that is part of every freight car bogey. Reaction-injection molding (RIM) combines two lowviscosity liquid streams consisting of a reaction catalyst and initiators (containing mostly monomer) inside the mold. The resultant polymer grows in molecular weight...
• Foam-friendly fridges
  Ever more stringent standards for energy efficiency force designers to plan carefully for the foam-insulation process. When a cabinet is filling with polyurethane foam, many physical and chemical reactions happen at once. Polymer formation reactions take place. The reaction of diisocyanate...
• Plastic industry honors innovative parts
  the People's Choice and Recreation/Leisure accolades for engine builder Mercury Marine. The entire assembly (top, front, lower, and rear cowls) keeps water away from the supercharged four-stroke-engine. Sheboyan Falls, Wis., molds the parts using a number of polymer alloys from Wilmington, Del. A 33%...
• Thermoformed tray takes abuse
  the choice of material, including the need to withstand aggressive cleansers, impacts, and abrasions. The team eventually settled on Kydex-T, a proprietary polymer alloy from Bloomsburg, Pa. The material is flame retardant and its elasticity, color consistency, and formability suit the twin-sheet molding...
