BASF has developed a new engineering plastic that markedly reduces the risk that electronic components will malfunction due to contact with moisture or oil. The electrical conductive paths of these components can easily be overmolded with the plastic to form a tight seal. This new material is a transparent, non-reinforced copolyamide (PA) that goes by the name Ultramid Seal-Fit.
It stands out for its very good adhesion to metals on the one hand and to plastics such as Ultramid (PA) and Ultradur (PBT) on the other hand. This product has been specially developed for the tight overmolding of metal inserts, thus accounting for an optimal bond in the component. Many approval samples have already been successfully tried out and the first serial applications are in the planning stage. The material is now already available in commercial quantities.
Metal parts thus overmolded are sufficiently sealed against water, oil and gas, as the experts of the Plastics Institute in Ludenscheid, Germany have demon¬strated in comprehensive temperature-shock tests on special test components. Among all of the other materials tested, this new BASF plastic best meets the requirements of the automotive industry. Application areas are sophisticated mechatronic components such as transmission and brake controls, sensors and plug-in connectors, especially in automotive construction.
