Chargar’s “LDPE” Soft Type Backer Rod

Chargar’s Soft Type Backer Rod is a soft, non-gassing, liable, bi-cellular backup material for construction joints and applications that require sealants.  It performs as a depth control for most known cold applied sealants and also helps sealant to assume the optimum hour-glass shape.  Sealant will not adhere to it; no bond breaker is required.
