IEP-Backer Rod’a Titan Foam®

The Titan Foam® is a soft, grey, non-gassing, pliable backer rod, with an impervious outer skin, used as a backing for elastomeric and other cold applied sealants.

Titan Foam® controls the depth of the applied sealants and ensures cross-sectional hour-glass configuration.

Specific Uses:

Suitable for applications such as irregular and varying joint widths where standard closed cell backer rods are not appropriate. Common applications include but are not limited to: concrete expansion and contraction joints, curtain walls, parking decks, bridge and highway construction, pavement maintenance, window glazing and log home chinking.

Composition and Materials: 

TITAN FOAM™ is an extruded polyethylene bi-cellular foam product which when punctured per ASTM C 1253 does not exhibit any out-gassing. TITAN FOAM™ has an impervious outer skin that resists moisture. It is easily compressible, flexible, and pliable for easy installation. It is furnished in a wide variety of sizes listed under packaging information.

Technical Data:

Mile High Foam® is chemically inert, resists oil, gasoline and most solvents. Material is odorless and will not stain.


Prior to installing TITAN FOAM™, all joints must be free from all contaminants such as curing compounds and form-release agents, as well as loose and foreign materials. Install TITAN FOAM™ under 25% minimum, 50% maximum compression to the depth recommended by the sealant manufacturer. Before applying sealant, all joints must be clean and dry.


TITAN FOAM™ is an inert material and therefore is compatible with virtually all known cold applied sealants including silicones, polyurethanes, acrylics, polysulfide, and butyl.

Physical Properties:
  • Density: 1.8 – 2.5 lb/ft3 ASTM D 1622
  • Out-gassing: NONE ASTM C 1253
  • Compression Recovery: 95% min ASTM D 5249
  • Tensile Strength PSI: 39-50 PSI ASTM D 1623
  • Temperature Range: -90 degrees F to 210 degrees F ASTM D 5249
  • Water Absorption: less than .03 g/cc ASTM C 1016 – Proc. B

Do not use with hot applied sealants. Do not puncture, over compress or stretch TITAN FOAM™ during installation.
