Haldia HDPE Halene-H E5201

Haldia Halene-H E5201 is a high density polyethylene grade developed by Haldia Petrochemicals Ltd. under its Halene-H trademark for demanding blow moulding and extrusion applications. Produced using the Mitsui CX Process, this grade is characterized by broad molecular weight distribution, strong environmental stress crack resistance, dependable processability, and a balanced mechanical profile that makes it highly suitable for industrial packaging and technical extrusion uses.

This is not a generic HDPE grade positioned for broad commodity use. E5201 is better understood as a high ESCR HDPE grade built for converters and industrial buyers who need better crack resistance, stable processing, and reliable performance in applications such as high ESCR containers, cable sheathing and jacketing, lamination film, general purpose film, extrusion applications, and DWC pipes. For Indian technical buyers, the presence of BIS designation code IS 7328-3B-BB-EXDA also strengthens its relevance in specification-driven procurement.

About the Manufacturer

Haldia Petrochemicals Ltd. is one of India’s established polymer manufacturers and markets its HDPE portfolio under the Halene-H brand. The company identifies Mitsui, Japan as the technology partner for its HDPE range, and the manufacturer’s own technical literature states that Halene-H is the registered trademark of Haldia Petrochemicals Limited for high density polyethylene.

Technical Specifications

Haldia Halene-H E5201 has a melt flow index of 0.35 g/10 min at 190°C/2.16 kg, which places it in a low-flow range suitable for blow moulding and extrusion applications where strength, melt stability, and performance consistency are important. The manufacturer technical sheet lists the annealed density at 0.950 g/cm³, while the HDPE product listing also shows 0.952 g/cm³ for the grade. For technical content, the TDS value should be treated as the primary reference, while the portfolio listing supports broader commercial positioning.

Its mechanical profile supports industrial use cases well. The grade offers tensile strength at yield of 25 MPa and tensile strength at break of 34 MPa, showing a useful balance between stiffness and durability. Elongation at break of 850% indicates strong toughness under stress, while flexural modulus of 1000 MPa supports shape retention in formed products. Hardness of 65 Shore D gives the material a solid rigidity profile, and notched Izod impact of 120 J/m supports resistance to impact during handling and service.

One of the most important technical advantages of E5201 is its ESCR F50 above 600 hours in 10% Igepal solution, which is highly relevant for buyers selecting HDPE grades for chemical exposure, stress-loaded packaging, and technical service environments. The grade also shows a Vicat softening point of 122°C, heat deflection temperature of 60°C, and DSC melting temperature of 130°C, all of which help technical teams evaluate suitability for processing and end-use conditions.

Applications and Industry Use Cases

High ESCR Containers

Haldia Halene-H E5201 is strongly positioned for high ESCR blow moulded containers where resistance to environmental stress cracking is critical. This makes it relevant for industrial packaging used for chemicals, detergents, pesticides, and other demanding contents where ordinary HDPE grades may face cracking risk over time. For buyers searching for high ESCR HDPE grade or HDPE for chemical containers, E5201 offers a technically grounded option supported by manufacturer guidance.

Cable Sheathing and Jacketing

E5201 is also recommended for cable sheathing and jacketing compounds, making it relevant for wire and cable manufacturers looking for HDPE with dependable extrusion behavior and balanced mechanical performance. In these applications, processors need a grade that can maintain consistency during extrusion while also contributing to durability and protective performance in the finished cable layer. This makes E5201 a commercially meaningful option for HDPE for cable sheathing and HDPE for cable jacketing searches.

DWC Pipes

The grade is associated with DWC pipe applications in the Haldia HDPE portfolio, which expands its relevance beyond packaging into infrastructure-linked extrusion uses. For this type of application, buyers typically look for a material that combines processability with structural integrity and service durability. E5201’s ESCR profile and mechanical balance support its use in such technical extrusion environments where long-term reliability matters.

Lamination Film and General Purpose Film

Haldia also recommends E5201 for lamination film and general purpose film applications. While it is not positioned as a specialty film grade in the same way as packaging film-specific materials, its processability and broad molecular weight distribution allow it to serve extrusion-based film requirements where toughness and functional performance are more important than premium optical properties.

General Extrusion Applications

For buyers seeking HDPE for extrusion applications, E5201 offers a practical balance of melt behavior, toughness, and crack resistance. It is especially suitable where the end use demands durability under load or exposure rather than only easy flow. This gives the grade broader industrial relevance across technical extrusion segments in India.

Comparable Alternatives

Within Haldia’s own portfolio, the closest comparable grade is E5201S, which shares the same 0.35 MFI but is listed at 0.958 density and is positioned more toward general purpose blow moulding and DWC pipes. In comparison, E5201 has stronger positioning for high ESCR containers, cable sheathing, and jacketing, making it the better fit where crack resistance and technical application matching are more important than a more general blow moulding profile.

B5500 is another relevant alternative, also at 0.35 MFI, but it is positioned for high ESCR bulk containers for chemicals and water tanks. Buyers choosing between E5201 and B5500 should think in terms of application focus: E5201 is more versatile across packaging, cable, and extrusion uses, while B5500 is more directly associated with bulk chemical and water storage applications.

B6401 differs more clearly in market positioning. With 0.40 MFI and a higher density profile, it is aimed at lubricant and edible oil containers rather than high ESCR technical packaging or cable-related use. That makes B6401 a better fit for rigid container applications focused on shape retention and packaging performance, while E5201 is the stronger choice for stress crack resistance, technical extrusion, and industrial service conditions.

The rationale behind E5201’s assigned grade positioning is therefore very clear: it fills the need for a high ESCR HDPE blow moulding and extrusion grade that bridges industrial packaging and technical extrusion applications, rather than serving only one narrow packaging segment.
