Backer Rods are typically made from closed-cell polyethylene or EPE (expanded polyethylene) foam. These materials provide durability, resistance to moisture, and compressibility, which are crucial for effective sealing applications.

Backer Rods come in various sizes, commonly ranging from 6 mm to 50 mm in diameter. Specific products may offer different lengths and thicknesses to suit various construction needs.

The temperature range for most Backer Rods is between -30°C to 120°C. This wide range allows them to be used effectively in diverse environmental conditions without compromising performance.

Installation requires ensuring that the joint is clean and free of contaminants. The rod should be compressed to about 25% to 80% of its original size to create a proper tooling base for the sealant application.

Yes, Backer Rods are designed to be resistant to water absorption, which helps maintain their structural integrity and effectiveness in sealing applications even in wet conditions.

Backer Rods are compatible with various sealants, including elastomeric types. They provide an inert backing that does not adversely affect the adhesion or performance of the sealants applied over them.

Backer Rods are primarily used in construction joints, expansion joints, precast concrete walls, and pavement maintenance. They help ensure effective sealing in environments such as bridges, parking decks, and glazing applications.

The Backer Rod is composed of extruded closed-cell polyethylene foam, which is resilient, compressible, and water-resistant.

It is used as a backup material in construction joints, controlling sealant depth, creating a backstop, and preventing sealant adhesion to the bottom of joints. Common applications include expansion joints, curtain walls, pavement joints, and log construction.

Key properties include a density of 1.3–1.9 PCF, tensile strength of 29–50 PSI, compression recovery above 90%, and water absorption below 0.5% by volume. It operates effectively within a temperature range of -40°F to 190°F.

Yes, it is compatible with most cold-applied sealants such as urethane, silicone, acrylic, butyl, polysulfides, and latex sealants. It does not adhere to sealants and acts as a bond breaker.

Sizes range from 3–10 mm (100 meters per roll) to 50–70 mm (2 meters per roll). Customized sizes and packaging are also available based on customer needs.

It is suitable for temperatures between -40°C to 120°C (-40°F to 190°F). Continuous use outside this range is not recommended.

Ensure the joint is clean and dry before installation. Select an oversized rod (20–30%) for proper fit and use a blunt tool for uniform placement without puncturing or stretching it.
