VESTODUR^® - Polybutylene Terephthalate

VESTODUR® is the brand name for a series of polybutylene terephthalate (PBT) compounds that have been carefully adapted to the requirements of processors and end-users.

Material properties characterizing VESTODUR® compounds are:

• high thermostability
• high stiffness
• low water absorption resulting in high dimensional stability
• high hardness and good strength
• good sliding friction behavior, low abrasion
• stable electrical properties
• good chemical resistance
• easy processability
• no tendency to form stress cracks

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.
