tin are loaded at a very high level (60 and 25 percent respectively) in
polyamide 6. The tin acts like a solder connecting the copper fibers.
conductivity of the compound is 1,000 times better than the next most
conductive plastic compound available (plastic loaded with steel fibers)," says

production part is a light that can be used for automotive or other end-market
production process is novel.
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
the material can be used for housings and lighting applications. The new
technology permits new design opportunities while also reducing costs through
integration of structural and electrical functions into one part.
electrical conductivity of the compound is in the range of 5 x 105
S/m. The conductivity of copper alone is 5.69 x 107 S/m.
the technology began with Siemens in 1998 and was later supported by IKV Aachen, a German research
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
In a world that's going green, industrial operations have a problem: Their processes involve materials that are potentially toxic, flammable, corrosive, or reactive. If improperly managed, this can precipitate dangerous health and environmental consequences.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
