产品描述
EVATANE® 28-40 is a random copolymer of Ethylene and Vinyl Acetate made by high-pressure radicalar polymerization process.
The high Vinyl Acetate content of EVATANE® 28-40 brings softness, flexibility and polarity. EVATANE® 28-40 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® 28-40 delivers high cohesive strength with most fillers and can be used to produce HFFR compounds or masterbatches.
