Evatane® 28-800

Ethylene Vinyl Acetate Copolymer

Arkema

产品说明：

EVATANE® 28-800 is a random copolymer of Ethylene and Vinyl Acetate made by high-pressure radicalar polymerization process.
The high Vinyl Acetate content of EVATANE® 28-800 brings softness, flexibility and polarity. EVATANE® 28-800 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® 28-800 delivers high cohesive strength with most fillers and may be used to produce masterbatches. It can also be used as a viscosity modifier for various EVA based compounds such as HFFR formulations for wires and cables.
