High-Performance Foaming Nucleating Agent for PE Coaxial Cables

This product is an exothermic nucleating agent, which can easily generate a large number of evenly distributed hot spots - nucleation points, and can effectively reduce the free energy barrier of nucleation, giving the foamed products fine and uniform pores, and is suitable for the physical foaming process of high-performance coaxial cables (CATV home cables).

1NS-CX0012, our premium exothermic nucleating agent engineered specifically for the physical foaming of polyethylene (PE) cables. This advanced additive is the key to achieving a perfect microcellular foam structure, which is critical for high-performance communication cables.

Our nucleating agent works by generating a vast number of evenly distributed nucleation sites upon heating. This intelligent action significantly lowers the free energy barrier required for bubble formation. The result? A exceptionally fine, dense, and uniform closed-cell foam structure that delivers unparalleled consistency and quality in your final cable products.

NS-CX0012 is an indispensable solution for manufacturers aiming to enhance product performance, reduce material usage, and improve production efficiency. It is particularly formulated for demanding applications like coaxial cables for CATV and broadband networks, where precise electrical properties and physical integrity are non-negotiable.



Key Benefits & Features

  • Superior Foam Structure: Promotes the formation of extremely fine, uniform, and closed cells, drastically improving foam quality.

  • Enhanced Nucleation Efficiency: High-density nucleation points ensure consistent and predictable foaming behavior across the production line.

  • Excellent Dielectric Properties: Maintains the critical electrical performance of the cable, ensuring low signal loss and stable impedance.

  • Optimized for Physical Foaming: Perfectly suited for use with physical blowing agents like nitrogen (N2) or carbon dioxide (CO2).

  • Easy to Use: Supplied in convenient yellow granular form for easy handling and homogeneous dispersion within the PE compound.

  • Proven Performance: Reliably improves production yield and minimizes defects like large, irregular voids.


Primary Application Fields

  • Coaxial Cables: Ideal for CATV (Community Antenna Television) drop cables, home cables, and broadband coaxial cables.

  • Communication Cables: Used in the insulation layer of various high-frequency data transmission cables.

  • Foamed PE Insulation: Applicable for any polyethylene-based insulation that requires a low dielectric constant through physical foaming.

  • High-Speed Foaming Lines: Enhances stability and cell density in modern, high-output extrusion processes.
