產(chǎn)品說明：
Elvax? 3120 is an extrudable ethylene-vinyl acetate copolymer resin available in pellet form for use in conventional extrusion equipment designed to process polyethylene resins.
Composition
Applications
Composition
- 7.5 % By Weight Vinyl Acetate comonomer content
- Slip additive, Antiblock additive.
- 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 film equipment 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.
