产品描述
EVATANE® 20-20 is a random copolymer of Ethylene and Vinyl Acetate made by high-pressure radicalar polymerization process.
The high Vinyl Acetate content of EVATANE® 20-20 brings softness, flexibility and polarity. EVATANE® 20-20 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® 20-20 can also be used as an additive for crude oil (pour point depressant) and for bitumen modification.
