Application Note

Better Characterization of Hot Melt Adhesives Using the Double Furnace DSC


Hot melt adhesives are a copolymer consisting of ethylene and vinyl acetate (VA). The end use properties of EVA copolymers, such as packaging films and hot melt adhesives, are very much dependent upon the level of the amorphous vinyl acetate component contained in the copolymer. The characterization of the thermal properties of EVA copolymers and hot melt adhesives is important for process optimization, product improvement and for quality assurance purposes.

This application note describes how PerkinElmer Double Furnace DSC, which is the only DSC that can provide very rapid heating and cooling, provides outstanding characterization information on hot melt adhesives.
