The Nomaflex REJ-050-4000-10 1/2 in. x 4 in. x 10 ft. Expansion Joint Filler (100 ft. Bundle) is a semi-rigid, closed-cell polypropylene foam that simply performs better and installs faster. Nomaflex is a closed-cell polypropylene foam that can be used in residential, commercial, civil, municipal and industrial applications. It will not absorb water, swell and disintegrate and it extends the service life of concrete by reducing the amount of imcompressible materials entering the joint. Nomaflex does not impede sealant cure time and can be used without a bond breaker with no impact on the long term performance of the sealant. Nomaflex resists oils, gas, salts, acetone and other chemicals. It does not leach like other products and is not sticky. Nomaflex is waterproof and can be stored outside. It will not break or flake due to weather elements. Nomaflex lasts longer and is 100% recyclable. Nomaflex fully complies with ASTM standard specification D 8139, and ASTM standard specification D 1751 for extrusion, compression recovery and water absorption as tested per ASTM test method D 545.
