Hi Doug:
Thanks for sharing your findings on insulating tape
and anti-static tape.
All insulators have the property of insulation
resistance. Modern insulations have insulation
resistances in the gigaohm and teraohm ranges.
I would guess that anti-static insulators have a
relatively low value of insulation resistance. From
what you describe, the manufacturer has assumed that
his anti-static material is not suitable as an
insulator, presumably because the insulation
resistance is relatively low.
The insulation resistance required by a circuit is
relative to the circuit resistances.
Insulation is in parallel to circuit resistances.
The effect of insulation resistance is usually
ignored because we assume the insulation resistance
is very high compared to the circuit resistance.
For relatively low circuit resistances, I would
think that relatively low insulation resistances
-- say megohm range -- would be acceptable. I
would think that one could use an anti-static
material as an insulator if the insulation
resistance was sufficiently high compared to the
circuit resistance.
I wonder of anti-static material manufacturers have
studied the long-term effects of various values of
working voltage on the material?
Best regards,
Rich
