Jacket Materials（PVC pellets）

    The Jacket Materials of a cable is the outermost protective layer that shields the inner components from mechanical damage, moisture, chemicals, UV radiation, and fire. Common materials include PVC for general indoor use, PE or HDPE for outdoor and underground installations, and LSZH for environments where low smoke and toxicity are required during fire. The choice of sheath material depends on the cable’s application, environment, and performance requirements such as flexibility, durability, and safety.

    1.Common Jacket Materials for Coaxial & Network Cables

    Material Name (English)Used InKey Features
    PVC (Polyvinyl Chloride)Coaxial & LANMost common. Low cost, flexible, flame-retardant. Ideal for indoor use.
    PE (Polyethylene)Coaxial & LANExcellent insulation, moisture and UV resistance. Used for outdoor or direct burial.
    HDPE (High-Density PE)Coaxial & LANTougher than standard PE. Better mechanical strength.
    LSZH (Low Smoke Zero Halogen)Coaxial & LANEmits low smoke and no toxic halogen gas during fire. Used in enclosed or public areas.
    TPE (Thermoplastic Elastomer)Coaxial & LANSoft, flexible, eco-friendly. Suitable for high-flex or handheld devices.
    PU / TPU (Polyurethane)Mainly CoaxialExcellent flexibility, oil & abrasion resistance. Good for harsh environments.
    FEP (Fluorinated Ethylene Propylene)High-end CoaxialHigh-temp, chemical & UV resistance. Used in high-frequency or special coaxial cables.

     Application Tips:

    • Indoor use (home, office):
      ➤ PVC is most common for both coaxial and LAN cables.
      ➤ LSZH is used when fire safety is important.

    • Outdoor use (direct sunlight, rain):
      ➤ PE or HDPE is preferred for both LAN and coaxial cables.

    • Direct burial:
      ➤ PE with water-blocking elements (like flooding gel or tape) is typically used.

    • Industrial or harsh environments:
      ➤ PU/TPU or TPE is suitable due to oil, abrasion, and mechanical resistance.

    • High-frequency or high-temperature coaxial cables (like RF, microwave):
      ➤ FEP or other fluoropolymers are ideal.

    Key Features :

    • Customizable: Formulated for different levels of flexibility, flame retardancy, temperature resistance, weather resistance, and color.

    • Good Electrical Insulation: Suitable for low- and medium-voltage cable insulation.

    • Flame Retardant Options: Can meet UL 94 V-0, IEC 60332, and other fire safety standards.

    • Cost-Effective: One of the most economical materials for cable sheathing.

    • Easy to Process: Well-suited for extrusion and injection molding.
