MIL-STD-670 TE12 Silicone Foam

MIL-STD-670 TE12 silicone foam from ElastaPro meets the requirements of a U.S. military standard for a closed-cell medium-density silicone foam that is used for sealing and gasketing applications. The TE12 designation indicates a specific firmness and density within the MIL-STD-670 standard, which has been canceled for new designs but remains valid for the procurement of replacement parts for existing equipment.

Medium-Density Closed-Cell Silicone Foam

MIL-STD-670 TE12 silicone foam is compressible, shock-absorbent, and resistant to extreme temperatures, UV, and ozone. Because it’s a closed-cell material, this military silicone is water-resistant. Its medium density makes it suitable for applications that require compressibility and a firm seal. Operating temperatures range from very low (-100°F) to very high (450°F). With its low compression set, this medium-density closed-cell silicone foam retains its original shape after being compressed.

Applications and Industries

MIL-STD-670 TE12 silicone foam is used for soft, compressible gasketing in military and industrial applications where a soft, compressible material is needed to absorb shock and maintain a seal under harsh conditions. Applications include sealing for electronics enclosures, vibration dampening in automotive and aerospace sectors, and protective seals for military vehicles, aircraft, and weapons systems.
