Product Description:
HF-4760 (BL3) is a high-density polyethylene (HDPE) grade containing 1-butene as a co-monomer. Its primary features include high density, superior stiffness, good ESCR (Environmental Stress Crack Resistance), excellent rigidity, and flowability. Additionally, it boasts good impact strength, making it ideal for small blow molding and container applications, particularly in demanding environments such as pharmaceutical and surfactant packaging.
Main Applications:
- Small blow molding products
- Bottles
- Containers (up to 5 liters)
- Packaging for pharmaceuticals and surfactants

Performance Highlights:
-
Density and Flowability:
- Mass Density of 0.954 g/cm³ ensures excellent structural integrity, making HF-4760 ideal for small blow-molded containers and bottles.
- The Melt Flow Rate (5.0 kg) of 1.2 g/10 min and Melt Flow Rate (21.6 kg) of 23 g/10 min indicate superior flowability, enabling consistent and efficient mold filling during production.
-
Mechanical Strength:
- Stress at Yield (26 MPa) and Stress at Break (32 MPa) ensure high mechanical strength and durability under physical stress.
- Flexural Creep Modulus (1300 MPa) and Tensile Modulus (1250 MPa) contribute to the material’s impressive stiffness and resistance to deformation.
-
Elongation and Impact Strength:
- With Elongation at Break >600%, HF-4760 can withstand significant stretching, making it durable for blow molding applications.
- Impact Strength (10 kJ/m² at 23°C) ensures resistance to physical shocks, making it reliable for demanding use cases.
-
Thermal Stability:
- The resin softens at 77°C, tolerates brittle temperatures below -80°C, and has high resistance to environmental stress and cracking (5 hours under full notch conditions).
-
Surface and Durability:
- Shore D Hardness (62) provides a robust surface finish suitable for blow-molded and packaged products.
- 100% Swell Ratio ensures dimensionally stable, high-quality output.
