Description: VESTODUR X9407 is a special compound polymer modified based on polybutylene terephthalate. The resin is used as an adhesive to bond together VESTAMID(polyamide 12) and VESTODUR (polybutylene terephthalate) in multilayer tubing 1000.1 (MLT 1000.1)developed by Degussa. MLT 1000.1 is a 3-layer-tubing comprising an outermost layer of VESTAMID LX9010, an adhesive layer of VESTODUR X9407, and an innermost layer of VESTODUR X9406. This MLT was developed as fuel line tubing with outstanding resistance against hydrocarbon permeation when alcohol containing fuels are used. VESTODUR X9407 provides excellent bonding between layers consisting of polybutylene terephthalate and polyamide 12 also after contact with fuels at elevated temperatures.
