Evatane®28-25
Ethylene Vinyl Acetate Copolymer
Arkema
产品说明：
EVATANE® 28-25 is a random copolymer of Ethylene and VinylAcetate 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 mosttackifying resins and waxes. Combined with a high fluidity, it isan efficient and easy handling product for hot melt adhesivesformulations. EVATANE® 28-25 delivers high cohesive strength withmost fillers and may be used to produce masterbatches or HFFRcompounds. EVATANE® 28-25 is also suitable for film extrusion.
