Closed Cell Foam Description: The Pelican Gun Cases are now available with closed cell Polyethylene foam. This plastic foam will not absorb water, is not affected by oils, acids, solvents or gasoline. What does this mean? It means that it will hold very small amounts of destructive moisture. It also means that the oils used to clean your guns will not deteriorate the foam as it happens with the standard open cell Polyurethane foam. This type of foam is a lot firmer and stiffer than open cell Polyurethane foam making it easier to cut when you are customizing the interior. It protects your weapons better. |
