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
Thilo Stier, innovation manager for A. Schulman.
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
BMW has already incorporated more than 10,000 3D-printed parts in the Rolls-Royce Phantom and intends to expand the use of 3D printing in its cars even more in the future. Meanwhile, Daimler has started using additive manufacturing for producing spare parts in Mercedes-Benz Trucks.
Researchers have been developing a number of nano- and micro-scale technologies that can be used for implantable medical technology for the treatment of disease, diagnostics, prevention, and other health-related applications.
SABIC's lightweighting polycarbonate glazing materials have appeared for the first time in a production car: the rear quarter window of Toyota's special edition 86 GRMN sports car, where they're saving 50% of its weight compared to conventional glass.
