Can you explain why is it correct to use WHEN rubbing not While rubbing ...?

Because we are concerned with the situation (the generation of static electricity), not the durational action (that is, we are not thinking about 'before' or 'after' rubbing the balloon).

A purist would dislike the dangling particle here. The electrons are not rubbing the balloon.
