产品描述
EVATANE® 40-55 is a random copolymer of Ethylene and Vinyl Acetate made by high-pressure radicalar polymerization process.
The high Vinyl Acetate content of EVATANE® 40-55 brings softness, flexibility, polarity and high solubility. EVATANE® 40-55 is compatible with most tackifying resins and waxes. Combined with a high fluidity, it is an efficient and easy handling product for hot melt adhesives formulations. EVATANE® 40-55 can also be used in solvent base adhesives, inks formulation and for making foams (shoe industry).
