Expanded polypropylene (EPP) The stuff that usually comes in boxes with stuff that you buy. When you break it, it gets everywhere. It can be made more sturdy or the exact opposite by application of the process. Expanded polypropylene (EPP) is an engineered plastic foam material. By combining polypropylene resin with magic dust, and applying heat, pressure and CO2 in an autoclave, the material is formed into small plastic beads. These small, closed-cell foam beads are injected into a steam chest to create parts custom moulded into complex shapes using steam heat & pressure.
Supreem That soft compressible stuff used primarily for computer and camera cases, packing and shipping, acoustical dampening and sound proofing. It is charcoal grey/black in color usually.
Polyethylene Polyethylene foam is a strong and resilient closed-cell foam. Ideally suited as the material or a component material in shock absorbing products, this closed-cell foam padding is also a great way to dampen the effects of vibration. This makes it an excellent packaging material for items that may receive indelicate handling or require long-distance transportation.
