It's a assembly hand tool which may be in contact with the ESD sensitive PCB.
I have some time to find out more detail about Pomolux too, only to hear about it's a kind of material which is widely used in ESD environment in replacing Delrin (not ESD compliance).
From the name "POM"olux, it sounds to be a modified POM (i.e. Acetal). Delrin is a tradename for Acetal/POM. So the Pomolux is probably a POM modified to have some electrical conductivity. You can find such materials at
I think the correct trade name you might be looking for is Pomalux. It's the trade name of one extruder for their semifinshed extruded acetal. It is co-polymer rather than homopolymer (Delrin). ESD normally stands for Electrostatic dissipative. In acetal this can be acheived by the additon of antistatic masterbatch and gives an off white colour but the mateial is suitable for use in clean rooms. Another possibility are ELS grades which use a high carbon black loading to get a degree of conductivity. There are several major extruders offering this type of material in rod and sheet. They would have their own trade names for the same material in extruded form.
Stainless steel fibre can also be added to give anti static or electrical shielding properties to plastics, including acetal co-polymer or homo-polymer.

You can also get mica coated with metal to impart electrical conductivity and Nyco are just releasing a wollastonite coated with metal. The conductivity relies on percolation (a continuous network of touching particles) so very anisotropic particles are more effective than round ones.
For ESD you don't need that much conductivity though so just carbon black of the right type should be enough.
