Expanded polypropylene (EPP)
Mold ability, light weight, good heat, oil, and insulating properties, excellent shape memory, ability to take multiple impacts
Expanded polyethylene (EPE)
Similar characteristics to EPP but with a very soft and smooth surface which lends itself well to packaging parts with sensitive finishes that require non-abrasive contact
