Product Overview
CRL Sof® Rod represents a cutting-edge sealant backing material that impeccably combines the best features of open and closed-cell backer rods into one trouble-free product. Sof® Rod is a continuous length of extruded polyolefin foam with a non-absorbent outer "skin" and an extremely resilient interior network of open and closed cells. Sof® Rod will not release gas if ruptured, and it can withstand temperatures ranging from -45°F to 160°F (-43°C to 71°C).
Key Features:
- Easily conforms to joint irregularities
- Non-gassing if damaged
- No moisture absorption
Product Warning: Note: Do not tear, puncture, crease, compress, or stretch during insertion. Always use the correct size backer rod for the particular application. Do not use hot-applied sealants or hot melt adhesives where their surface temperature is over 160°F (71°C).
