...tronics industry for heat resistance, particularly for the use of lead-free solders, since they have a 30°C higher working temperature than conventional lead-containing solders. Solder-Resistant PBT Degussa offers Vestodur CL where short-term heat-resistant materials are required, for example for soldering processes. The radiation-crosslinkable polybutylene terephthalate (PBT) – when glass-fibre reinforced – withstands maximum temperatures up to almost 500°C, and is less expensive than convent...

... ingredients or body fluids. These include housing parts as well as infusion and transfusion components like connector pieces, adapters and multi-way taps, such as the three-way taps made by B. Braun Medical AG of Switzerland (see photo). Special Vestodur formulations are similarly licensed for direct contact with active ingredients. These PBT moulding compounds are easy to process and the moulded parts produced from them display a particularly high dimensional stability for a low sliding fricti...

...er the past few years are already on the market as commercial applications, including radiation crosslinkable grades for SMD production of electronics components to withstand the very high soldering temperatures that briefly prevail (such as Vestodur X9410, manufacturer: Degussa). New on the market are PBT grades with a considerably higher flow rate, including Pocan and Crastin grades, as well as SF grades of Arnite, where the producer especially stresses the combination of an easy-flowing melt,...

...ed with the challenge of developing a material with a higher short-term heat resistance but with PBT's customary set of properties. The obvious solution appeared to be to modify PBT for this purpose so that it satisfied the requirements (Grade: Vestodur X9410, Manufacturer: Degussa AG, Düsseldorf/Germany). The modification is incorporated firmly in the polymer chain, thus avoiding the use of any additives that could evaporate and damage the electrical contacts. As a result of the modificatio...

...0 at 0.75 mm in tests.Strict regulations for fire protection of cable materials are becoming more and more important in tenders for public buildings. Evonik Industries AG of Essen, Germany, is offering the cable industry a series of Vestodur PBT and Vestamid polyamide 12 molding compounds for use with fiber optic cables. They provide safe, efficient protection for insulating fiber optic cables, circuitry and cable conduits. Vestodur X9426A is a new, halogen-free PBT molding compound (HFFR) with ...
