Polyethylene wax (PE wax) is a versatile, low molecular weight polyethylene polymer renowned for its unique properties, including low viscosity, high melting point, hardness, and thermal stability. These characteristics make it indispensable across various industries. Gulbrandsen, a global leader in chemical manufacturing, offers a diverse range of specialty polymers that cater to these industrial needs. As a high-performance polyethylene wax for industrial applications, it enhances efficiency and quality in multiple sectors.

Applications of Polyethylene Wax

1- A Nucleating Agent in EPS

In EPS (Expanded Polystyrene) production, the nucleation stage plays a crucial role in determining the quality and characteristics of the final foam. Gulbrandsen’s high-purity Polyethylene (PE) Waxes function as highly efficient nucleating agents, engineered to improve foam structure, reduce density, and streamline processing.

With consistent molecular structure and excellent thermal properties, our PE Waxes enable precise control over cell formation—making them a valuable additive in achieving superior EPS performance.

Key Benefits of Using Gulbrandsen’s PE Wax as a Nucleating Agent:

• Enhanced Cell Nucleation:
  Promotes the development of fine, uniform, and closely packed cells, resulting in improved surface aesthetics and thermal insulation properties.
• Lower Foam Density:
  Enables the production of low-density EPS with better stability and performance, contributing to material savings and efficiency.
• Faster Pre-Puff Maturation:
  Accelerates the aging process of pre-expanded beads, reducing cycle time and improving production throughput.
• Improved Mechanical Strength:
  Delivers stronger foam at target densities by promoting optimal cell distribution and reducing voids.
• Reduced Cooling and Molding Time:
  The wax’s excellent thermal characteristics support quicker heat transfer during molding, allowing faster cooling and shorter cycle times.
• Superior Fusion and Mold Release:
  Acts as a processing aid that enhances bead fusion and simplifies demolding, helping reduce scrap and improve production consistency.
