An interesting design innovation at K 2010 is an electrically conductive plastic compound from A. Schulman being used by a Finnish lighting manufacturer. Copper and tin are loaded at a very high level (60 and 25 percent respectively) in nylon 6. The tin acts like a solder connecting the copper fibers. “The conductivity of the compound is 1,000 times better than the next most conductive plastic compound available (plastic loaded with steel fibers),” says Thilo Stier, innovation manager for A. Schulman. The first production part is a light made by Hella.
The production process for the light is a great story. First, the ABS plate and the PMMA (acrylic) reflector are injection molded in a three-component process. The electrical resistor, diodes, LED and contact pins for the plug are inserted and connected with the new conductive compound, which is called Schulatec TinCo 50. The ABS-coated reflector is then mounted to ensure watertight encapsulation.
Stier says the material is good for housings and lighting applications.

A Columbia University team working on molecular-scale nano-robots with moving parts has run into wear-and-tear issues. They've become the first team to observe in detail and quantify this process, and are devising coping strategies by observing how living cells prevent aging.
Many of the new materials on display at MD&M West were developed to be strong, tough replacements for metal parts in different kinds of medical equipment: IV poles, connectors for medical devices, medical device trays, and torque-applying instruments for orthopedic surgery. Others are made for close contact with patients.
