Description
Low-Density Polyethylene — LDPE LFI2121
High-Performance Cable Insulation & Sheathing Grade LDPE — Producer: Arya Sasol Petrochemical Company (ASPC) | Supplier: MizanPetroGas Company
Product Introduction
LDPE LFI2121 is a specialized, high-purity low-density polyethylene grade engineered specifically for power cable insulation, telecommunication jacketing, and wire sheathing. Produced by Arya Sasol Petrochemical Company (ASPC) using tubular high-pressure technology and supplied internationally by MizanPetroGas Company, this grade provides reliable dielectric insulation, low dissipation factor, and smooth extrusion rheology at elevated line speeds.
Formulated with high cleanliness standards and tailored antioxidant stabilization, LDPE LFI2121 protects conductors from moisture intrusion, chemical exposure, and dielectric breakdown in low-voltage and medium-voltage electrical cable systems.

Technical Profile and Structural Properties
LDPE LFI2121 is synthesized via tubular high-pressure free-radical polymerization of high-purity ethylene monomer. With a nominal Melt Flow Index (MFI) of 2.1 g/10min (at 190°C / 2.16 kg) and a calibrated base density of 0.921 g/cm³ (921 kg/m³), the polymer architecture exhibits a controlled distribution of long and short-chain branching that ensures low die swell, uniform cross-sectional cable wall thickness, and high drawdown speeds without melt fracture.
The resin is reinforced with a balanced phenolic/phosphite antioxidant system to inhibit thermal-oxidative degradation during extrusion and prevent copper-catalyzed aging in direct contact with metallic conductor cores.

Thermal Aging Stability
Integrated antioxidant package protects the polymer matrix against thermal oxidation during extrusion and continuous service.
Moisture & Ingress Barrier
Non-polar polyolefin structure prevents water migration, preserving insulation resistance in wet and underground conduits.
Flexibility & Toughness
Maintains bending flexibility and notch toughness at sub-zero temperatures, preventing jacket cracking during installation.
Conductor Adhesion & Strippability
Provides uniform adhesion to metallic conductors while allowing clean strippability during field cable termination.
