Elvax® 3182

Ethylene Vinyl Acetate Copolymer

DuPont Packaging & Industrial Polymers

产品说明：

DuPont™ Elvax® 3182 is an extrudable ethylene-vinyl acetate copolymer resin available in pellet form for use in conventional extrusion equipment designed to process polyethylene resins.
Composition

• 28 % By Weight Vinyl Acetate comonomer content

• Thermal Stabilizer: BHT antioxidant

Applications

• 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 or cast and cast coextrusion film equipment over a wide range of line speeds and film thicknesses. It can also be coextruded with a variety of other polymers. This resin is typically used as a low temperature seal layer in coextruded films.
