This is a Source Control Drawing and Parts List for a Closed Cell Foam Cushioning Material. The document provides detailed specifications for polyethylene foam materials used in fabrication, supplied by Sealed Air Corporation from Louisville, Kentucky.

The parts list specifies eleven foam sheet components with varying specifications across multiple parameters. Materials are available in waterproof or black finishes, with grades ranging from Type I to Type V, and densities from 2.2 PCF to 9.6 PCF. Part numbers include configurations such as -1, -1B, -2, -3, -3B, -4, -5, -5B, -6, -7, -7B, and -8, with corresponding drawing numbers and current tooling information provided. Key requirements include polyethylene foam materials meeting A-A-59136 specifications unless otherwise specified, anti-static additive homogenization during manufacturing to achieve electrostatic decay times not exceeding 60 seconds per EIA Standard 541, and foam density and conductivity requirements within specified ranges. The document prohibits residual explosive blowing agents above 10% of the lower explosive limit and restricts water absorption to less than 1.0 x 10⁻³ grams per square foot. Military grade white foam is available as a special order through Sealed Air. The drawing is maintained by the Naval Surface Warfare Center at Crane Division, with approval dated June 6, 1985, and distribution authorized for public release with unlimited distribution.
