In late 1997, the long-standing Federal Specification for polyethylene foam for packaging, PPP-C-1752 was canceled, and two Commercial Item Descriptions (CIDs) were issued to take its place.
Although there is some similarity between the CIDs and the Federal Specification they replace, the CIDs require compliance with fewer property limits, and generally have less stringent test requirements. Many government users are finding the replacement CIDs to be insufficient for their needs, so we anticipate The Dow Chemical Company will continue to receive inquiries relative to PPP-C-1752 compliance for some time. In general, the ETHAFOAM products, which were certified to meet PPP-C-1752 requirements, also meet the CID requirements. Where test data to certify to this fact is available, the product certification documents have been edited to reflect compliance with both PPP-C-1752 and the appropriate CID.
The table below gives a quick reference to which ETHAFOAM products fit into which classification under both the new CIDs and the former Federal Specification. Further information regarding each CID is given following the tables.
