| description | Polymer compositions containing a polyoxymethylene base polymer that is compounded with a conductive filler and pigment carbon black are disclosed that exhibit electrostatic dissipative (ESD) capabilities while also being laser weldable. The polymer composition can be formed into shaped or molded articles such as filters, flanges, connectors, etc. for use in fuel systems where conductivity, ductility, weldability, and resistance to aggressive fuels are required. The compositions can be compounded into a pellet product which can then be formed into a shaped article that complies with the ESD capabilities required by SAE J1645. At the same time, parts produced from the compositions can absorb laser energy sufficiently to form a high quality welded interface with parts produced from other compositions that are transparent to laser radiation and cannot absorb laser energy sufficiently. |
