Talk:Blue Camp Pad

You are mistaken in separating the "blue camp pad" from polyethlyene.

Camp pad is not an "alternative to polyethylene" because camp pad IS polyethylene. In fact it's also basically the same non-crosslinked type as the white cube under the "polyethylene" entry. The rectangular PE foam used for packing is typically of higher density than the camp pad.

Polyethlyene has many different attributes: 1. Crosslinked vs non-crosslinked 2. EVA (only shows up in crosslinked versions AFAIK). EVA is a softening additive. 3. Density. Some of the heaviest PE foams are 5x or more heavier than the lightest 4. HDPE vs LDPE. HDPE is a VERY rare type, only mfg'd by Zotefoam. Really tough, stiff-as-a-board stuff even in light weights. 5. Ionomeric polyethylene- very tough non-crosslinked, very rare, very expensive. 6. Any number of other exotic additives, flame retardency, etc. There are literally millions of formulations.
