Anti Static & E Con wheels are categorised according to level of resistivity. Anti static wheels generally have resistivity ratings of below: 10 ^ 6 (ohms) Electrically conductive wheels have a resistivity rating that is below: 10 ^ 4 Ohms. Whilst the term anti static generally refers to its ability not to generate a charge upon frictional contact with another material, if a charge is generated, it will be a frcition of what would otheriwse be the case through of contact electricfication.
CONDUCTIVE MATERIALS ON THE OTHER HAND ALLOOW CHARGES TO GO TO THE GROUND MORE EASILY AND THERBYPROTECT AGAINEST SHOCK OR DAMAGE TO EQUIPMENT WHICH IS SENSITIVE TO ELECROSTATIC DISCHARGE (ESD) ECON WHEELS ARE ALSO USED IN CLEAN ROOMS, LABS AND SO ON ALSO.
