产品描述
Ethylene – Vinyl Acetate – Maleic Anhydride Terpolymer
OREVAC® T 9305 is a random terpolymer of ethylene, vinyl acetate and maleic anhydride made by high-pressure radicalar polymerization process. As an ethylene copolymer, OREVAC® T 9305 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.
Applications
OREVAC® T 9305 is compatible with most tackifying resins and waxes and can be used for hot melt adhesives formulations. OREVAC® T 9305 is also suitable to produce thermo-adhesive films for solid substrates like PA, PET & PU films, aluminium foils...
