New Molex plastics connector modules made of Ultradur The electronics company Molex Elektronik is using Ultradur High Speed B4300 plastics from BASF for the housings of a new hybrid automotive connector.
The electronics company Molex Elektronik GmbH of Ettlingen, Germany,
a subsidiary of Molex Automotive, is using Ultradur® High Speed B4300
– BASF’s PBT (polybutylene terephthalate) with improved flow
properties – for the housings of a new generation of 16-contact
connectors. These so-called Sicma-hybrid connectors are employed for fuse
and relay boxes in the interior of vehicles. This particularly easy-flowing material yields components having very thin walls and the filling procedure during injection molding is done without unduly stressing the material. “This ensures that the well-balanced mechanical properties of the material are retained. As a result, a housing made of Ultradur High Speed can accommodate cables with large diameters better than had been possible with the PBT used up until now,” explains Günther Kaminsky, product manager at Molex in Ettlingen. The production of this new generation of connectors calls for a combination of the requisite strength and good elasticity. “And on top of it all, this has to be done at competitive component costs since we are aiming for an annual production volume of more than 5 million connectors.”
In plastics, good flowability also means that the injection molding tool
can be filled without unduly stressing the material. This property characterizes
Ultradur® High Speed, which the Molex company employs in its new generation
of 16-contact connectors for safety and relay boxes. As far as its dyeing
properties are concerned, this flow-improved PBT made by BASF displays
considerable advantages over conventional PBT (polybutylene terephthalate)
grades. Molex Elektronik GmbH of Ettlingen belongs to Molex Automotive Europe,
a subsidiary of Molex Incorporated. This American company is headquartered
in Lisle, Illinois and, with its almost 28,000 employees, ranks among
the three largest manufacturers of industrial connectors and connector
modules. Ultradur® is BASF’s tradename for its line of partially crystalline saturated polyesters. This line is based on poly(butylene terephthalate) and is employed in applications demanding a high performance level such as load bearing parts in different industrial sectors. Ultradur® is outstanding for its high rigidity and strength, very good dimensional stability, low water absorption and high resistance to many chemicals. Moreover, Ultradur® exhibits exceptional resistance to weathering and excellent heat aging behavior.
