🔷 Comprehensive Introduction to HDPE HBM 5510 – A Powerful Grade for Large Blow-Molded Parts

HDPE HBM 5510 is one of the most specialized high-density polyethylene grades produced by Arya Sasol Polymer, specifically designed for large blow-molded parts, industrial gallons, and open-top drums up to 110 liters. This grade is produced using 1-hexene as the comonomer and offers an exceptional combination of high strength, excellent processability, outstanding melt strength, and superior chemical/environmental stress crack resistance (ESCR).

🔹 Key Features of HDPE HBM 5510

✔ High Strength and Excellent Stiffness

With a density of 0.955 g/cm³ and a tensile modulus of 1000 MPa, this grade withstands mechanical loads and operational stresses in industrial applications.

✔ Excellent Processability

• MFI = 0.5 g/10 min (at 5 kg)
• HLMI = 10 g/10 min (at 21.6 kg)

These values allow manufacturers to produce large blow-molded parts with stable parison behavior and uniform wall thickness.

✔ Superior ESCR Performance

Stress crack resistance:
ESCR F50 = 110 hours (100% Igepal)
This property is crucial for gallons, chemical containers, and detergent packaging.

✔ Remarkable Impact Strength

• Tensile Impact: 135 kJ/m² at −30°C
• Izod Impact: 22 kJ/m² at 23°C

These figures show that HDPE HBM 5510 delivers reliable performance under impact, pressure, and drop conditions.

🔹 Thermal Properties

• Vicat A/10N = 127°C
• HDT (1.8 MPa) = 45°C

These thermal values ensure dimensional stability and reliable performance during transportation and storage.

🔹 Main Applications of HDPE HBM 5510

This grade is ideal for producing:

• Standard and lightweight gallons
• Open-top drums up to 110 liters
• Large industrial blow-molded parts
• Chemical-resistant containers
• Packaging containers for detergents and oils

Its blow-molding performance provides excellent surface quality, bubble stability, and uniformity.

🔹 Additives in This Grade

• Antioxidant: Yes
• Slip: No
• Antiblock: No
• Processing Aid: No

The antioxidant improves the thermal stability of the polymer during processing.

🔹 Recommended Processing Conditions

• Extruder zone temperature: 180–220°C
• Melt temperature: 200–235°C

These ranges provide the best balance between parison quality, output rate, and final mechanical properties.

🔹 Safety, Storage, and Handling Notes

• Avoid exposure to hot air during melting; fumes or irritating vapors may form.
• Store in a dry, cool environment, away from direct sunlight and below 50°C.
• When burned, the resin produces dense black smoke and high heat.
• HDPE should ideally be used within 6 months to prevent property degradation.

🔹 Conclusion

HDPE HBM 5510 is a powerful, durable, and economical choice for manufacturers of industrial blow-molded parts. With its balanced combination of stiffness, flexibility, chemical resistance, impact strength, and excellent processability, this grade is an ideal option for gallons, industrial containers, and robust open-top drums.
