Evonik Unveils HFFR PBT Grade for Optical Fiber Jackets and Wire Bundles

Published on 2015-03-02. Author : SpecialChem

ESSEN -- Strict fire safety regulations for cable material are increasingly becoming the norm in calls for tenders for public construction projects. Evonik Industries, Essen, now offers a new halogen-free polybutylene terephthalate (PBT) grade for optical fiber jackets and wire bundles, with excellent flame-retardant properties (HFFR). VESTODUR® X9426 has a high limiting oxygen index (LOI) and low smoke density, and any smoke gases emitted are of low toxicity. The extruded material is also extremely flexible, kink- and crush-resistant and has good hydrolysis properties.

Evonik offers a range of VESTODUR® PBT and VESTAMID® polyamide 12 compounds for the cable industry. These are used both for the safe and efficient protection of optical fibers and for wire insulation and cable protection tubing. The latest development in PA 12 is a material that meets the stringent HL3 requirements for rail vehicles in accordance with standard EN 45545 – 2:2013.
