Dielectric Properties

  1. May 5, 2004 #1
    Where should I go to identify some very basic dielectric properties of the following materials: PVC, polyethylene, polystyrene, glass, acrylic, nylon, polyester?? I'm trying to determine whether these materials have negative or positive charges and how the charge is determined. My son, a 4th grader, is participating in a science fair....Thanks

    Try GE and DuPont web sites. I think they made most of these. They should have information on many properties.

    I don't know what you mean by having positive or negative charges. They should all be neutral, though some may have more of a propensity to accumulate positive or negative ions.
