Epe Foam BAcker Rod

About Epe Foam BAcker Rod

An EPE foam backer rod is made from expanded polyethylene foam, which is a closed-cell, lightweight, and compressible material. It is inserted into joints (such as cracks, gaps, or expansion joints) before applying sealant, helping to control the depth and shape of the sealant bead.

Reliable Sealant Backing Solution

EPE Foam Backer Rod is engineered for construction professionals seeking dependable sealant backing and crack filler solutions. Its versatile sizing and excellent compressibility deliver consistent results in both horizontal and vertical joints. Designed for easy installation, the rod's lightweight and flexible structure facilitate hassle-free handling on the job site.


Expanded Polyethylene Advantage

Manufactured from non-staining, odorless EPE foam, the backer rod ensures there's no chemical interference with sealants or surrounding materials. Its closed-cell structure minimizes water absorption to less than 1%, providing robust moisture resistance-a crucial attribute for insulation and joint sealing applications.


Durability and Performance

With a tensile strength of 0.16 MPa and an impressive compression recovery of over 80%, the EPE Foam Backer Rod can withstand repeated compressions and recover its shape, supporting long-lasting joint integrity. Its Shore 00 hardness level offers the perfect balance between softness and structural support, making it fit for both indoor and outdoor environments.
