ChemLink HBR-Rod Closed-Cell Backer Rod

ChemLink HBR-Rod Closed-Cell Backer Rod Flexible Foam Rods For Use As Backer For Sealants ChemLink HBR-Rod is a round, flexible, continuous lengths of extruded, closed-cell polyethylene foam backer rod for use as a backing material for elastomeric and other cold applied sealants. TYPE: C - Per ASTM C 1330. Cylindrical, flexible sealant backings composed predominantly of closed cell material per ASTM C 1330 for use with cold applied sealants. TYPE: 3 -Per ASTM D 5249. Round rods of various diameters for use with cold applied joint sealants. TEMPERATURE LIMITS: -45°F to +160°F. Chemlink HBR-Rod Benefits ChemLink HBR-Rod limits the depth of the sealant and prevents excessive sealant use. It also helps sealant assume optimum shape factor to prolong sealant service life and acts as a barrier to the flow of sealant through the joint. Chemlink HBR-Rod Compatibility Closed-cell polyethylene foam is an inert material; and therefore, it is compatible, both physically and chemically, with virtual
