HMEL HDPE Polysure B0155D

HMEL HDPE Polysure B0155D is a 1-hexene co-monomer based high density polyethylene blow moulding grade produced by HPCL-Mittal Energy Limited using Advanced Dual Loop Slurry MarTECH technology. Developed for general-purpose blow moulding, this grade is widely used for containers up to 20 litres, jerry cans, and double-walled corrugated pipes where processors need strong melt strength, reliable die swell, and stable parison control.

HPCL-Mittal Energy Limited operates an integrated petrochemical complex and markets its polyethylene portfolio under the Polysure brand. Within this range, B0155D is positioned as a general-purpose HDPE blow moulding grade for industrial and packaging applications that demand balanced stiffness, toughness, and processability. Its 1-hexene co-monomer structure and slurry technology platform support the combination of melt strength and end-use durability required in larger blow-moulded packs and technical extrusion applications.

Technical Specifications and Deep Technical Insights

B0155D has a melt flow index of 0.35 g/10 min and a density of 0.955 g/cc, making it suitable for blow moulding applications where parison stability and wall-thickness control are critical. The low MFI supports stronger melt behavior during extrusion, which helps processors maintain better shape retention in larger containers and jerry cans.

The grade offers hardness of 62–63 Shore D, tensile strength at yield of 27–29 MPa, elongation at break of 600–900%, and flexural modulus of 1000–1050 MPa. For manufacturers, this means the resin combines rigidity with useful toughness, allowing finished containers to resist deformation while still handling impact and stress during filling, stacking, transport, and use.

B0155D also shows notched Izod impact of 150–160 J/m and ESCR of 25–35 hours, which are important for applications involving detergents, lubricants, and chemical exposure. ESCR is especially relevant in blow moulded packaging because it indicates how well the material can resist cracking under stress in aggressive environments.

From a thermal standpoint, the grade has a Vicat softening point of 125–127°C and heat deflection temperature of 73–75°C. These values support its use in rigid packaging and industrial applications where dimensional stability under moderate heat exposure matters.

Typical processing guidance includes barrel temperatures of 170–200°C and die temperatures of 150–190°C. In production terms, this gives processors a practical operating window for maintaining melt strength, die swell behavior, and efficient blow moulding performance. Buyers comparing HDPE blow moulding grades often look at MFI, density, ESCR, impact, and stiffness together, and B0155D stands out as a well-balanced option for medium-to-large container production.

Applications

Lube Oil and Edible Oil Containers

B0155D is well suited for blow-moulded containers up to 20 litres used in lube oil and edible oil packaging. Its melt strength helps maintain parison stability during moulding, while its stiffness supports container shape, stacking performance, and resistance to panel bulging during storage and transport.

Jerry Cans and Chemical Packaging

For jerry cans and household or industrial chemical containers, B0155D offers a useful combination of rigidity, impact resistance, and environmental stress crack resistance. This makes it a practical choice for detergent packs, lubricant containers, and similar packaging formats where durability under handling and chemical contact is important.

Pharmaceutical, Cosmetic, and Personal Care Packaging

The grade is also relevant for blow-moulded pharmaceutical and cosmetic packaging where processors need consistent conversion behavior and dependable finished-part quality. Its balanced mechanical profile supports rigid containers that require clean moulding performance and stable wall formation.

Double-Walled Corrugated Pipes

Beyond packaging, B0155D is used in double-walled corrugated pipe applications where melt strength and structural integrity are important. The grade supports extrusion performance needed for pipe profiles used in underground cable protection and light drainage systems.

Performance Benefits

B0155D is valued for exceptional processability, very good melt strength, and excellent die swell properties in blow moulding operations. These characteristics help processors improve parison control, maintain wall-thickness consistency, and reduce production instability in larger containers. Its balanced stiffness and ESCR profile also make it commercially attractive for converters serving oil, detergent, chemical, and technical pipe markets.

Comparable Alternatives

Within the HMEL portfolio, M2050S is positioned for thin-wall injection moulding and M0662D is aligned more with crate and industrial moulded products, so they are not direct substitutes for B0155D in blow moulding. B0155D remains the primary HMEL option when the application requires blow-moulded containers or corrugated pipe structures.

Compared with GAIL B53A003U, B0155D competes in the blow moulding space for packaging containers, but B0155D is strongly positioned where processors need a combination of melt strength, die swell, and suitability for larger formats up to 20 litres. Against OPaL B55H03 and similar IOCL blow moulding grades, B0155D stands out as a practical Indian HDPE grade for jerry cans, edible oil packs, detergent containers, and technical pipe applications.

The rationale behind this grade is clear: it is assigned to applications that need low-flow blow moulding behavior, good rigidity, useful ESCR, and stable processing rather than injection moulding speed or pipe-grade pressure performance.
