Degussa AG Vestodur® X4159 Modified Polyester PBT for Fiber Optic Jacketing
Subcategory: Polyester, TP; Polybutylene Terephthalate (PBT); Thermoplastic
Material Notes: Description: Degussa AG’s High Performance Polymers Business Unit manufactures a range of polybutylene terephthalate compounds that are supplied 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
Specific Notes for this Material: X4159 is a modified polyester grade with a markedly higher flexibility, suitable where the flexibility of PA 12 secondary coatings has been insufficient. Recommended for tight buffering. Information provided by degussa.
