| Evonik manufactures a range of polybutylene terephthalate (PBT) compounds and supplies it under the registered trademark VESTODUR®. Material properties characterizing VESTODUR® compounds are: high thermostability high stiffness low water absorption resulting in high dimensional stability high hardness good strength good sliding friction behavior, low abrasion good creep behavior good electrical properties good chemical resistance good weathering resistance good processability no tendency to form stress cracks Applications VESTODUR® compounds can be used for a wide range of applications, for example, for thin-walled injection-molded parts in electrical engineering applications, for especially dimensionally stable components of high surface quality in the automotive industry, as a barrier layer in multilayer fuel lines, for laser-markable components, and in the cable industry. High-molecular extrudable VESTODUR® specialty products have come to occupy a leading position as materials for secondary fiber optic jacketing, because they fulfill the requirements perfectly.&& |
