Evonik Vestodur® X9412 Black E70203 Conductive, Impact Modified PBT (discontinued **)
Categories:	Polymer; Thermoplastic; Polyester, TP; Polybutylene Terephthalate (PBT); Polybutylene Terephthalate (PBT), Impact Grade
Material Notes:	Description: VESTODUR X9412 is a conductive, impact modified compound based on polybutylene terephthalate. It is used as an inner layer resin in multilayer tubing 1040.2 (MLT 1040.2) for fuel lines to prevent against electrostatical charging. MLT 1040.2 is a 4 layer-tubing comprising an outermost layer of VESTAMID LX9010, an adhesive layer of VESTODUR X9407, a barrier layer of VESTODUR X9406 and an innermost layer of VESTODUR X9412. This MLT was developed as fuel line tubing with outstanding resistance against hydrocarbon permeation especially when alcohol containing fuels are used. Information provided by degussa. Evonik Industries is the successor company to Degussa.
