PBT
赢创(原德固赛)(Evonik)
产品描述
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.
