DuPont Elvaloy®AC 3427 is a granular EBA copolymer with 27% butyl acrylate content. Processable on standard LDPE extrusion equipment, it is suitable for film blowing, cast film and co-extrusion processes with a wide processing temperature window, serving as a preferred raw material for efficient toughening modification of polyolefin materials.
Excellent process adaptability, compatible with standard LDPE film blowing and cast film equipment without additional production line modification.
Wide processing window with melting temperature ranging from 160°C to 285°C, flexibly meeting the requirements of different co-extrusion substrates.
Significant toughening effect, with good compatibility with PE, PP and other polyolefin resins, improving the impact resistance of modified products.
Good thermal stability, with a maximum processing temperature of up to 310°C, no obvious degradation during high-temperature processing, ensuring stable product performance.
High molding precision, with clear temperature parameter guidance for film blowing and cast film processes, facilitating precise process control.
Polyolefin blown film products, used to produce high-toughness packaging films and improve the puncture and tear resistance of films.
Cast film/sheet processing, suitable for food packaging, industrial film and other fields, optimizing film flexibility and heat-sealing performance.
Polyolefin co-extruded composite films, used as raw material for the toughening layer to enhance the interlayer adhesion and impact resistance of multi-layer film structures.
Modification of PP injection-molded products, improving the low-temperature crack resistance of home appliance shells, auto parts and other products.
Modification of polyethylene pipes, enhancing the weather resistance and external impact resistance of pipes and extending service life.
