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 said in a press release.
The company 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 fibres and for wire insulation and cable protection tubing. The latest development in PA 12 is a material that meets the stringent Hazard Level (HL3) requirements for rail vehicles.
Evonik is active in over 100 countries around the world. In fiscal 2013, more than 33,500 employees generated sales of around €12.7 billion and an operating profit (adjusted EBITDA) of about €2.0 billion. (GK)
