Description

HDPE 52B18, or BG-HD-52B18, is a high-density polyethylene (HDPE) grade specifically formulated for injection molding applications. Its medium density ranges between 0.951 and 0.953 grams per cubic centimeter at 23°C, and a melt flow index (MFI) of 15-21 g/10 min at 190°C with a 2.16 Kg load.

  • Butene-1 (C4) Comonomer: This addition enhances the material’s properties, including easy processing, high rigidity, and strength.

Physical Properties:

  • Melt Flow Rate (MFR): 15-21 g/10 min at 190°C/2.16 Kg, indicating its flow behavior during processing.
  • Density: 0.951-0.953 g/cm³ at 23°C, placing it within the medium-density category of HDPE.
  • Bulk Density: Approximately 0.57 g/cm³, affecting the material’s compactness and weight per unit volume.
  • Tensile Strength @ Yield: 25-27 MPa, showcasing its ability to resist deformation under tension.
  • Tensile Strength @ Break: Greater than 14 MPa, demonstrating its ultimate tensile strength.
  • Elongation @ Break: More than 150%, indicating its ductility and ability to stretch significantly before breaking.
  • Vicat Softening Temperature: Between 130-134°C, relevant for its thermal processing capabilities.
  • Flexural Modulus: 1300-1400 MPa, reflecting its stiffness.
  • Izod Impact: 36 J/Min, showing its resistance to impact forces.

HDPE 52B18 is versatile and has applications in general-purpose items and thin-walled foam containers. Its combination of strength, rigidity, and ease of processing makes it suitable for a wide array of injection-molded products, including:

  • Storage Containers: For household and commercial use, benefiting from its durability and resistance to impact.
  • Foam Packaging: Providing cushioning and protection for delicate items during shipping.
  • Industrial Parts: Where high strength and rigidity are required, such as in automotive components or hardware.

  • Acid Scavenger
  • Antioxidants
  • Lubricants
  • UV Stabilizer
