Polyurethane timing belts can generate substantial static charges during normal use, which can be dissipated by means of a TransDev antistatic coating and tested by means of a TransDev Antistatic Conductivity Meter.
Dielectric materials are by definition poor conductors of electricity. When such materials are separated after contact with either a conducting material or another insulating material, a static electric charge can be produced by the capacitance effect, which can lead to sparking or crackling. This effect can also occur with belts which are insulating when they run on metal pulleys. The electric discharges which result can cause the following problems:
- Interference with electronic equipment
- Risk of ignition or explosion of flammable materials
- Risk of shocks to the operator from the high
voltages which can be generated
