Foamed adhesive system.

Highly reactive adhesive polymers from the company can be crosslinked with UV radiation, and subsequently expanded into low density foamed adhesive systems. This development has been catalyzed by a highly crosslinkable SBS grade, allowing for new application development and market opportunities, according to the company. This SBS grade specifically targets technically demanding applications, such as automotive. Applications include use in sprayable foamed adhesives, the preparation of gaskets and sealants having the ability to expand in place, and potentially in acoustical and vibration damping applications. Facilitated by the highly crosslinkable SBS grade, the company is said to have produced reactive adhesive systems which can be easily processed and then crosslinked by exposure to UV radiation. This polymer technology is said to be extremely advantageous, as it couples the inherent processability and functional advantages of SBCs with a number of performance properties typically associated with thermoset polyurethane and natural rubber adhesive systems, according to the company. The end result is said to expand the capabilities of SBC adhesive systems to higher service temperature ranges and improved solvent and chemical resistance. (Kraton Polymers LLC) www.kraton.com
