Evatane® 28-25

EVATANE® 28-25 is a random copolymer of Ethylene and Vinyl Acetate made by high-pressure radicalar polymerization process.

The high Vinyl Acetate content of EVATANE® 28-25 brings softness, flexibility and polarity. EVATANE® 28-25 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® 28-25 delivers high cohesive strength with most fillers and may be used to produce masterbatches or HFFR compounds. EVATANE® 28-25 is also suitable for film extrusion.
