| OREVAC® T 9304 is a random terpolymer of ethylene, vinyl acetate and maleic anhydride made by high-pressure radicalar polymerization process. As an ethylene copolymer, OREVAC® T 9304 is compatible with PE in all proportions, and with most other ethylene copolymers. Vinyl acetate brings softness, flexibility and polarity, maleic anhydride gives reactivity, leading to versatile adhesive properties to polar and non polar substrates. As a result of high-pressure polymerisation in tubular reactor, OREVAC® T 9304 exhibits high transparency (low haze). Applications OREVAC® T 9304 is compatible with most tackifying resins and waxes and can be used for hot melt adhesives formulations. OREVAC® T 9304 is also suitable to produce thermo-adhesive films for solid substrates like PA, PET & PU films, aluminium foils, fiber mats, foams… OREVAC® T 9304 can also be used as a tie layer between polyethylene and polyamide in blown film coextrusion.&& |
