Specified polyamide Ultramid® EQ for sensitive automotive electronics
applications under harsh conditions.
Electronic assemblies in modern transmission control units or safetyrelated applications such as airbag and anti-lock systems are becoming ever more compact and complex. They are also often exposed to high ambient temperatures and aggressive media such as oil. The delicate circuits are more frequently connected to semiconductors via thin wires which is known as wire bonding. In such surroundings, disruptive effects such as corrosion, ion migration, electrolyte formation, and creep currents can arise and in extreme cases cause entire assemblies to fail. Plastics for housings and components have to be equipped in such a way that they do not react with the metals involved and thus prevent electronic failure.
All Ultramid® EQ grades have an organic heat stabilizer with a very low halogen content of less than 1 ppm. This prevents halogens like iodine or bromine from damaging metal wiring, ions from reacting with the metals, and undesired electric currents from arising. In addition to the specified formula and complex production process, all Ultramid® EQ charges are checked carefully. This ensures that the manufacturing process does not introduce any halogen contamination to the material. The relevant certificate is provided to customers if desired. The new Ultramid® EQ portfolio is also well-suited for use in electric and hybrid vehicles with elevated AC and DC voltages. For more information: www.ultramid.de
