Low-Density Polyethylene 2420K, commonly referred to as Lupolen 2420K, is a versatile LDPE grade designed for a wide range of industrial and packaging applications. Its well-balanced physical and mechanical properties make it suitable for demanding processing and end-use environments, although it is not recommended for medical or pharmaceutical applications.
With a density of 0.924 g/cm³ and a melt flow index (MFI) of 4 (190 °C / 2.16 Kg), this polymer provides an optimal combination of flexibility, toughness, and processability.
Supplied in granular (pellet) form and containing no additives, LDPE 2420K ensures clean and consistent processing. It is produced by Amir Kabir Petrochemical Company under HS Code 39011030
Good Heat Seal Performance
LDPE 2420K provides excellent heat-sealing capabilities, forming strong, reliable seals even at lower temperatures. This makes it highly suitable for flexible packaging applications, ensuring product protection and secure closures without compromising mechanical strength.
Good Optical Properties
With high clarity and gloss, this grade enhances the visual appeal of final products. Its excellent transparency is particularly valuable in food and consumer packaging, where product visibility is critical for both branding and quality assurance.
Good Processability
2420K is easily processed across multiple manufacturing techniques, including extrusion and molding. Its controlled melt flow index ensures smooth processing, reduced cycle times, and cost-efficient production, making it adaptable for a wide variety of end uses.
High Tensile Strain
Offering superior elongation at break (up to 300% in machine direction and 600% in transverse direction), this grade ensures exceptional flexibility and stretchability. These properties make it ideal for stretch films and other applications requiring deformation resistance without material failure.
Balanced Mechanical Properties
LDPE 2420K demonstrates a well-rounded profile of strength, flexibility, and durability. With a reliable tensile modulus, tensile stress at yield, and tensile strength across directions, it ensures stable performance in demanding packaging and industrial applications.
LDPE 2420K is a versatile low-density polyethylene grade that combines optical clarity, flexibility, and mechanical strength, making it suitable for a wide range of industrial and consumer applications. Its adaptability across packaging, hygiene, construction, and automotive sectors highlights its value as a reliable material for both performance and efficiency.
