The control of electrostatic discharge (ESD) is desirable for many app
lications of polymer materials in automated device handling equipment.
Materials such as polysulfone (PS), polyether-sulfone (PES), polyethe
r-etherketone (PEEK), and polyetherimide (PEI) are used for conditioni
ng chamber walls, guide rails, stop pins, contactor sockets, etc. Thes
e polymers have excellent thermal and electrical insulating capabiliti
es, low coefficients of thermal expansion, and superior machinability.
