All applications feature the same specialty characteristics
- 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
Specialty VESTODUR® polybutylene terephthalate compounds are licensed for direct contact with active ingredients. These compounds are easy to process and the moldings made of them are dimensionally stable. They feature low sliding friction. Thus, on the one hand, dimensionally stable housings like pipette housings and functional components of inhalers can be made with them. But VESTODUR® is also suitable for processing with the melt-blow process, where the structure of the non-wovens produced can be adjusted. They are used as blood filters, for example.
Special high moleculare, extrudable VESTODUR® compounds have become leading materials for secondary fiber optic jacketing. They perfectly protect the optical fibers due to their mechanical properties - on demand also with excellent flame retardant characteristics.
Computer keyboards made of laser-markable VESTODUR® compounds retain the sharp contours of their lettering, even after millions of keystrokes. High contrast and contour sharpness are also essential for secure transfer of the encoded information in bar codes or data matrix codes. Laser marking is not only possible in parts made of natural-colored resins but also in colored products, with good color constancy. The patented additive allows a high staining depth, but only a small foaming height, so that the inscribed characters are more resistant to abrasion than in other systems. Compounds and markings feature high chemical resistance and light stability.
