I believe they all have slightly different densities, but if you're pressed for time, judge by appearance, details of the crime, and any burn tests given to you.SciOly15 wrote:I have a polymer flowchart, but the problem is that it doesn't differentiate between PC and PMMA, and PETE and PVC. Do you guys have any ways you differentiate between those two pairs?
PC: Clear. Used in eye protection, as well as in other projectile-resistant viewing and lighting applications that would normally indicate the use of glass, but require much higher impact-resistance.
PMMA: Clear. Used in aquariums, intraocular lenses, acrylic paint, dentures, and more.
PETE: Typically clear, perhaps with green or blue tint. Common in drinking bottles. Resin ID code of 1.
PVC: Typically opaque white with a slight yellowish tint. I'd describe it as eggshell, almost. Resin ID code of 3. Gives off hydrogen chloride gas when burned. Common in plumbing.
Hope that helps!
