Description
High-Density Polyethylene — HDPE BL3 (Blow Molding Grade)
High-Rigidity & Superior ESCR Resin for Bottles, Jerrycans & Small Containers — Commercial Trade Names: MPC BL3 / HF4760 / BG-HD-BL3 — Supplier: MizanPetroGas Company
Product Introduction
HDPE BL3 (marketed under industry trade designations including MPC BL3, HF4760, and BG-HD-BL3) is a prime high-density polyethylene resin engineered specifically for extrusion blow molding (EBM) of hollow containers, consumer bottles, and industrial jerrycans up to 10 liters. Featuring a high density of 0.954 g/cm³ and a controlled melt index of 1.2 ± 0.3 g/10 min (190 °C / 5.0 kg), this grade delivers an optimal balance of structural rigidity, parison swell consistency, and environmental stress cracking resistance (ESCR).
Supplied globally by MizanPetroGas Company through direct sourcing partnerships with leading petrochemical manufacturers (including Bakhtar Petrochemical, Jam Petrochemical Company, and Marun Petrochemical), HDPE BL3 is widely utilized in the manufacturing of detergent bottles, chemical containers, edible oil packaging, personal care bottles, and export-grade industrial packaging.

Technical and Structural Profile
HDPE BL3 is synthesized through the copolymerization of ethylene with 1-butene (C4) comonomer, producing a tailored molecular weight distribution that provides the high melt strength needed to prevent parison sag during continuous or accumulator extrusion blow molding. The crystalline density of 0.954 g/cm³ provides exceptional flexural stiffness (Tensile Modulus ~ 1100 MPa), ensuring that blow-molded containers possess high top-load compressive strength for multi-tier warehouse pallet stacking.
Formulated with a balanced additive stabilization system comprising calcium stearate acid neutralizers and secondary phosphite/phenolic antioxidants (Irganox 1010 & Irgafos 168), BL3 provides high thermal stability across broad melt processing temperatures (180 °C – 200 °C) while maintaining tight mold shrinkage tolerances (1.5% – 2.5%) for precise neck and thread definition.

Technical and Industrial Advantages
High Top-Load Compression
High stiffness (Tensile Modulus ~ 1100 MPa) allows blow-molded bottles and jerrycans to withstand heavy pallet stacking loads without side-wall buckling.
Surfactant Stress-Crack Immunity
Superior ESCR performance prevents stress cracking and seam leaks when packaging aggressive household detergents, bleaches, and industrial cleaners.
Precision Neck & Thread Definition
Predictable mold shrinkage (1.5–2.5%) ensures precise cap-thread sealing, eliminating liquid leakage during automated filling and transport.
Drop Impact Durability
High break elongation (> 400%) and polymer toughness prevent bottle rupture and seam splitting when containers are dropped from standard handling heights.
High-Speed Cycle Efficiency
Optimal crystallization kinetics allow rapid mold in-cavity cooling, shortening blow molding cycle times and boosting production output.
Material Weight Optimization
High mechanical modulus enables bottle light-weighting (down-gauging) without sacrificing side-wall rigidity or vacuum resistance.
