Nomaco SOF Soft Bi-Cellular Polyethylene Foam, Backer Rod, 5/8" Diameter, Sold by the Foot

This Nomaco SOF Rod is a soft bi-cellular polyethylene foam backer rod used in concrete construction. It is comprised of both open and closed cells that will not out-gas when skin is ruptured and prevents sealant bubbling and failure.

SOF Rod has an outer skin and resilient interior network of cells and helps cold-applied sealants assume the optimum hour-glass shape to prolong the sealant service life. It is commonly used in applications such as expansion and contraction joints, window glazing, curtain-wall construction partitions, parking decks, bridge construction, modular-home gasketing and log-home chinking.

SOF rod is comprised of an inert material and is physically and chemically compatible with virtually all known cold-applied sealants including self-leveling types. Water resistant.
