HMEL HDPE Polysure B0053D

HMEL HDPE Polysure B0053D is a 1-hexene co-monomer based high molecular weight high density polyethylene produced by HPCL-Mittal Energy Limited using Advanced Dual Loop Slurry MarTECH technology. This large blow moulding grade is developed for heavy-duty hollow articles where processors need excellent processability, high melt strength, good die swell, low parison sagging, high ESCR, and dependable stackability.

HPCL-Mittal Energy Limited is one of India’s major integrated petrochemical manufacturers, and its Polysure HDPE portfolio serves blow moulding, injection moulding, and pipe-related applications across industrial sectors. Within this range, B0053D is positioned as a large blow moulding specialist for 240 litre L-ring drums, open top drums, and industrial tanks. Its 1-hexene co-monomer chemistry and slurry technology platform support the melt strength and structural balance required for large hollow articles where parison control, wall distribution, and long-term durability are critical.

Technical Specifications and Deep Technical Insights

B0053D has a melt flow index of 0.08 g/10 min at 190°C/5 kg and 2.5 g/10 min at 190°C/21.6 kg, along with a density of 0.953 g/cc. This very low-flow, high molecular weight profile is especially important in large blow moulding because it supports strong melt strength and reduces parison sagging during production of large drums and tanks.

The grade delivers tensile strength at yield of 27 MPa, elongation at break of 900%, and flexural modulus of 1100 MPa. For manufacturers, this means the resin combines rigidity with very good toughness, helping large containers maintain shape while also resisting cracking, impact damage, and handling stress during filling, transport, storage, and repeated industrial use.

B0053D also offers ESCR of 300 hours and notched Izod impact with no break at 23°C, both of which are highly relevant for industrial chemical packaging. ESCR is a major selection factor in large blow moulded drums because it indicates how well the material can resist crack formation under load when exposed to detergents, chemicals, or other aggressive contents.

From a thermal standpoint, the grade has a Vicat softening point of 127°C and heat deflection temperature of 80°C. These values support dimensional stability in industrial storage and transport applications where large containers may face moderate thermal exposure in warehousing or field conditions.

Typical processing guidance includes barrel temperatures of 180–210°C and die temperatures of 160–200°C. In practical terms, this gives processors a stable operating window for maintaining melt strength, die swell behavior, and better wall-thickness consistency in large hollow parts. Buyers comparing HDPE large blow moulding grades typically assess MFI, density, ESCR, impact, and sag resistance together, and B0053D stands out as a purpose-built option for large industrial drums and tanks.

Applications

240 Litre L-Ring Drums

B0053D is highly suitable for 240 litre L-ring drums where large-part stability and wall-thickness control are essential. Its high melt strength and low parison sagging help processors produce drums with better dimensional consistency, which is important for industrial liquid storage and transport.

Open Top Drums

For open top drums, B0053D offers the structural balance needed for heavy-duty industrial packaging. Its toughness, rigidity, and chemical resistance make it a practical choice for containers that must withstand repeated handling, stacking, and demanding logistics conditions.

Industrial Tanks and Chemical Storage

Industrial tanks and chemical storage containers require a resin with strong ESCR, impact resistance, and dependable processability. B0053D fits these applications well because it supports large blow moulded parts that need long-term durability in contact with aggressive contents and rough operating environments.

Bulk Liquid Transport Containers

The grade is also relevant for bulk liquid transport containers used in industrial supply chains. Its stackability and resistance profile help improve performance in applications where container integrity during transport and warehousing is a key buying factor.

Performance Benefits

B0053D is valued for high melt strength, good die swell, low parison sagging, and useful ESCR in large blow moulding operations. These characteristics help processors improve parison control, reduce instability in large parts, and produce drums and tanks with more reliable wall distribution. Its impact resistance, chemical resistance, and stackability further strengthen its position in industrial packaging applications.

Comparable Alternatives

Within the HMEL portfolio, B0148D is better suited for medium blow moulding applications up to 120 litres, while B0155D is more aligned with smaller containers up to 20 litres. B0053D is the stronger HMEL choice when the application involves 240 litre drums, industrial tanks, or large hollow articles where very high melt strength and low sagging are more important than faster processing for smaller packs.

Compared with GAIL B53B005, OPaL B55L03, IOCL 55GB003, and similar Indian large blow moulding grades, B0053D stands out as a practical option for industrial drums and tanks where processors need a low-flow HDPE with strong parison stability and chemical durability. The rationale behind this grade is clear: it is assigned to large blow moulding applications that demand melt strength, stackability, ESCR, and industrial toughness rather than medium-container flexibility or injection moulding efficiency.
