What Is LDPE JD-6116 and Its Applications?

LDPE JD-6116 is a low-density polyethylene (LDPE) compound developed for cable insulation and sheathing. It combines the flexibility and lightweight nature of LDPE with enhanced processability, electrical performance, and durability, making it a reliable material for communication, power, and industrial cable applications.

Composition and Properties

• Base Resin: LDPE (Low-Density Polyethylene)

• Additives: Antioxidants, stabilizers, and processing aids to improve thermal and mechanical performance

• Processing Method: Optimized for extrusion to ensure smooth cable insulation and sheath surfaces

Key Features

• Excellent Electrical Insulation with high dielectric strength

• Good Flexibility for ease of installation and handling

• Lightweight & Low Density, reducing cable weight

• High Processability, suitable for high-speed extrusion

• Chemical Resistance to acids, alkalis, and common solvents

• Cost-Effective compared to more advanced materials like XLPE

Applications

• Communication Cables: Insulation for telephone and data transmission

• Power Cables (Low Voltage): Inner insulation for household and industrial wiring

• Coaxial & Signal Cables: Provides insulation and protection for stable signal transmission

• Packaging & Films (Secondary Use): Due to its flexibility and softness, it can also be adapted for non-cable uses

Advantages

• High purity and insulation stability for reliable electrical performance

• Flexible and easy to process in complex cable designs

• Smooth extrusion surface, reducing friction during cable installation

• Economical material choice for large-scale cable manufacturing

Technical Parameters (Typical)

• Density: 0.918–0.922 g/cm³

• Melt Flow Index (MFI): 1.5–2.5 g/10 min (190°C/2.16 kg)

• Tensile Strength: ≥10 MPa

• Elongation at Break: ≥300%

• Dielectric Strength: ≥25 kV/mm

• Volume Resistivity: ≥10¹⁴ Ω·cm

Limitations

• Lower heat resistance than XLPE and LLDPE

• Not suitable for medium- or high-voltage power cables

• Susceptible to environmental stress cracking compared to HDPE/LLDPE

FAQs

Q1: What is the main advantage of JD-6116 over LLDPE cable materials?
JD-6116 provides higher softness and easier processing, while LLDPE offers better crack resistance and toughness.

Q2: Can LDPE JD-6116 be used outdoors?
It can be used outdoors if properly stabilized, but for long-term UV exposure, black LLDPE or HDPE is preferred.

Q3: Is it suitable for fiber optic cables?
Yes, JD-6116 can be used as an insulation layer in communication and fiber optic cables.

Q4: How does it compare to XLPE?
JD-6116 is more cost-effective and flexible, while XLPE provides higher temperature and voltage resistance.
