Elvax®3182-2

Ethylene Vinyl Acetate Copolymer

DuPont Packaging & Industrial Polymers

产品说明：

DuPont™ Elvax® 3182-2 is an extrudable ethylene-vinyl acetatecopolymer resin available in pellet form for use in conventionalextrusion equipment designed to process polyethylene resins.

Composition

• 28 % By Weight Vinyl Acetate comonomer content

• Thermal Stabilizer: non-BHT antioxidant

Applications

• This resin is designed to provide a low temperature heat seal toitself or many other materials commonly used in flexible packagingapplications. The melt properties of this resin allow it to beprocessed on blown or cast and cast coextrusion film equipment overa wide range of line speeds and film thicknesses. It can also becoextruded with a variety of other polymers. This resin istypically used as a low temperature seal layer in coextrudedfilms.
