Haldia HDPE Halene-H B5500

Haldia Halene-H B5500 is a high molecular weight high-density polyethylene (HMHDPE) blow moulding grade manufactured by Haldia Petrochemicals Ltd. under the Halene-H trademark. Produced using the Mitsui CX Process, this grade is designed for demanding blow moulding applications where high environmental stress crack resistance, strong rigidity, excellent mechanical properties, and dependable impact resistance are essential. In the Haldia HDPE portfolio, B5500 is positioned for high ESCR bulk containers for chemicals, detergent containers, lube oil packs, and water tanks, making it one of the more application-specific industrial blow moulding grades in the range.

Industrial buyers searching for Haldia B5500 HDPE, high ESCR bulk container grade, HDPE for detergent containers, HMHDPE water tank grade, or Haldia blow moulding grade are typically looking for a resin that can handle tougher service conditions, larger part sizes, and more demanding packaging environments. B5500 matches that requirement very well.

About the Manufacturer

Haldia Petrochemicals Limited is an established Indian polymer manufacturer and markets its HDPE grades under the Halene-H brand. The official Haldia product ecosystem identifies Mitsui, Japan as the technology partner for the HDPE line, which strengthens the technical credibility of the grade for industrial buyers and procurement teams.

Technical Specifications and Material Strength

Haldia Halene-H B5500 has a melt flow index of 0.06 g/10 min at 190°C/2.16 kg, 0.35 g/10 min at 190°C/5 kg, and 8 g/10 min at 190°C/21.6 kg. This flow profile reflects the grade’s HMHDPE character and supports its use in blow moulding applications where melt strength, wall integrity, and structural performance are important. The manufacturer reports density of 0.952 g/cm³ by ASTM method and 0.956 g/cm³ by JIS method, which supports its rigid and durable material profile for industrial packaging and tank applications.

The grade offers tensile strength at yield of 27 MPa and tensile strength at break of 40 MPa, along with elongation at break of 850%. This indicates a material that is not only rigid but also capable of handling deformation and service stress without early failure. Flexural modulus of 1000 MPa contributes to structural stability, while hardness of 64 Shore D supports a solid and durable end-product feel. Its notched Izod impact strength of 500 J/m is especially valuable for larger blow moulded parts that must survive handling, transport, and industrial use.

A major technical advantage of B5500 is its ESCR F50 above 1000 hours in 10% Igepal solution, which is a strong indicator of crack resistance in demanding chemical and detergent packaging environments. The grade also shows Vicat softening point of 127°C, heat deflection temperature of 63°C, and DSC melting temperature of 133°C, giving processors and technical buyers a fuller picture of its thermal behavior and application suitability.

Applications and Industry Use Cases

Chemical Bulk Containers

Haldia Halene-H B5500 is highly suitable for high ESCR bulk chemical containers, especially where the packaging must withstand chemical contact, long storage cycles, and physical handling. In these applications, environmental stress crack resistance becomes one of the most important material selection factors. B5500’s technical profile makes it a strong fit for industrial chemical packaging where reliability and structural durability are critical.

Detergent Containers

Detergent packaging places stress on plastic materials because detergent formulations can accelerate cracking in lower-performance grades. B5500 is well positioned for detergent containers because its high ESCR and impact resistance help the finished pack remain durable through filling, transport, stacking, and end use. This makes it highly relevant for buyers searching HDPE for detergent containers and high ESCR blow moulding grade.

Lube Oil Packs

For lube oil containers and packs, B5500 offers a strong balance of rigidity, toughness, and blow moulding processability. This helps converters produce packs that maintain shape well while also resisting handling damage. In industrial and automotive packaging, that balance is important because the container must perform well in both logistics and end-user handling.

Water Tanks

B5500 is also recommended for blow moulded water tanks up to 1000 litres, with external UV stabilizer suggested for outdoor use. This makes the grade especially relevant for larger storage products where long-term toughness, crack resistance, and structural integrity are essential. For buyers looking for HDPE water tank grade in India, B5500 has a clear and manufacturer-backed application advantage.

Comparable Alternatives

Within the Haldia HDPE portfolio, B6401 is a more specific alternative for lubricant and edible oil containers up to 20 litres. Compared with B5500, B6401 is better suited to smaller rigid packaging applications, while B5500 is the stronger choice for larger, more demanding, and more chemically exposed blow moulded products.

E5201 is another relevant comparison grade. It is positioned for high ESCR containers, cable sheathing and jacketing, and DWC pipes, which gives it a broader technical extrusion and cable-related role. B5500, by contrast, is more directly aligned with bulk blow moulding applications such as chemical containers, detergent packs, and water tanks. Buyers choosing between the two should think in terms of end use: E5201 is broader across extrusion and technical applications, while B5500 is more specialized toward larger blow moulded industrial packaging.

E5201S is a more general-purpose blow molding and DWC pipe grade. It works well where the need is broader and less severe. B5500 is the better fit when the application demands higher ESCR, stronger impact resistance, and more confidence in larger blow moulded parts. That is the core rationale behind the assigned grade positioning of B5500 in the Haldia lineup.
