Ethylene Vinyl Acetate Copolymer
DuPont Packaging & Industrial Polymers
产品说明:
DuPont™ Elvax® 3135X is an extrudable ethylene -vinyl acetate copolymer resin available in pellet form for use in conventional extrusion e designed to process polyethylene resins.
Composition
12 % By Weight Vinyl Acetate comonomer content
Thermal Stabilizer: BHT antioxidant
Application
This resin is designed to provide a low temperature heat seal to itself or many other materials commonly used in flexible packaging applications. The melt properties of this resin allow it to be processed on blown film e over a wide range of film thickness and blow-up ratios. It can also be co-extruded with a variety of other polymers. This resin is typically used as low temperature seal layer in co-extruded films.
