Ethylene-vinyl acetate copolymer wax. Used in hot-melt adhesives as an hardener, viscosity reducer and dispersing aid for dyes.
VESTOWAX is synthetic waxes produced essentially by two different processes, the Ziegler polymerization and the Fischer-Tropsch process. The Ziegler polymerization of ethylene synthesizes polyethylene waxes with different densities and molecular weights depending on the preparation conditions. The Fischer Tropsch process yields straight chain products possessing low viscosity in the melt and having molecular weights between 500 and 1000g/mol.
