I've read that common plastics will generally create the greatest static charge.

Materials that don't easily transfer charges are called insulators.

One of the best known insulators are common plastics

Just need clarification on this, as it seems a little contradictory at first.

How can common plastic build up a big charge in the first place, if they don't easily transfer charges?

Is it that they build up a charge over time, more slowly than other materiials, and that they keep them longer so that when they do transfer then it's a big transfer?

Also, what will cause this transfer.I mean doesn't the conductor have to be 'stronger' than the insulator, ie' more force pulling the electons/charge.

Here's a quick rundown on Electrostatics for you, Flex


Shocking reading, I tell you .....

 

noooooooooooooooooooooooo that was bad jak!

bet you fancy yourself as a bright spark huh? lol.

to be honest, i think plastics have a greater ESD because they build up the charge but because they're not so good conductors, it doesnt go anywhere, until it finds a really easy discharge route (you/your electronics!)

Lol, I realsie I was getting it the wrong way around slightly now.

Thanks for the link.

I'm going to drill this into my head so that it's always there for recall when needed
