IOCL HDPE Propel 003DB52

IOCL HDPE Propel 003DB52 is a high molecular weight bimodal high density polyethylene grade developed by Indian Oil Corporation Limited under the Propel brand for medium blow moulding and sheet extrusion applications. Produced using LyondellBasell Hostalen slurry process technology, this grade is designed for processors who need good processability, balanced stiffness, and dependable impact performance in larger blow moulded containers and industrial packaging formats.

Indian Oil Corporation Limited is one of India’s largest integrated petrochemical manufacturers, supplying HDPE and PP grades across packaging, blow moulding, injection moulding, raffia, and pipe applications. Within the IOCL Propel portfolio, 003DB52 is positioned in the HDPE blow moulding segment as a medium blow moulding grade for containers and bottles up to 100 litres, while also supporting sheet extrusion applications. This positioning makes it commercially relevant for converters serving industrial packaging, lubricant packaging, utility containers, FMCG packaging, and selected regulated contact applications where documentation and processing stability matter.

Technical Specifications and Deep Technical Insights

IOCL HDPE Propel 003DB52 has a melt flow index of 0.32 g/10 min at 190°C/5 kg and 9.5 g/10 min at 190°C/21.6 kg, along with a density of 0.952 g/cm³. This property profile reflects a high molecular weight bimodal HDPE resin engineered for medium blow moulding, where processors need a combination of parison strength, stable processing, and finished container rigidity.

The grade delivers tensile strength at yield of 32 MPa, elongation at yield of 10%, flexural modulus of 1300 MPa, notched Izod impact strength of 300 J/m at 23°C, and a Vicat softening point of 126°C. These values indicate a resin that offers a useful balance between stiffness and toughness, helping converters produce containers that hold shape well while still resisting handling stress and impact during transport and use.

A major technical advantage of 003DB52 is its bimodal molecular structure, which supports good processability and a broader performance balance in medium blow moulding applications. In practical converter terms, this means the grade is better suited to larger container formats than small bottle-focused GPBM grades, because it supports the combination of melt strength, rigidity, and impact behavior needed in medium-capacity packaging.

The recommended processing temperature range is 180 to 220°C. IOCL also notes the importance of proper storage and handling. The resin is supplied in 25 kg raffia bags and should be stored in a dry, protected environment away from prolonged sunlight exposure, since poor storage can affect bag condition and material quality.

Applications

Containers and Bottles up to 100 Litres

IOCL HDPE Propel 003DB52 is primarily suited for containers and bottles up to 100 litre capacity where processors need a medium blow moulding HDPE grade with reliable parison behavior, good stiffness, and impact support. This makes it relevant for industrial packaging, utility containers, and larger rigid blow moulded packs that must maintain shape during filling, stacking, and transport.

Medium Blow Moulding Applications

For medium blow moulding lines, 003DB52 offers a practical balance of processability and mechanical performance. Converters working with medium-capacity bottles, jerry-style packs, and industrial containers can benefit from a resin that runs consistently while supporting strong finished part performance.

Sheet Extrusion Applications

Beyond blow moulding, the grade is also recommended for sheet extrusion applications. This expands its usefulness for processors who need a versatile HDPE grade that can support rigid industrial sheet and utility product manufacturing where stiffness and durability remain important.

Lubricant and Utility Packaging

The grade can be used in packaging formats for lubricants, household chemicals, and utility products where larger pack sizes demand better structural integrity than small retail bottles. Its balanced stiffness and impact profile make it suitable for these practical packaging environments.

Food and Regulated Contact Packaging

Because IOCL documentation references compliance for foodstuff, pharmaceutical products, and drinking water contact, 003DB52 also carries added value for buyers who require documentation-backed confidence in regulated packaging applications. This is especially useful where procurement teams evaluate both performance and compliance support before grade selection.

Comparable Alternatives

Within the IOCL portfolio, 003DB52 and 012DB54 serve different blow moulding needs. 012DB54 is a general purpose blow moulding grade intended for smaller bottles and containers up to 5 litres, with stronger positioning around small-pack packaging. 003DB52, by contrast, is assigned to the medium blow moulding segment for containers and bottles up to 100 litres, making it the more suitable option where larger capacity, stronger parison behavior, and medium-pack structural performance are required.

Compared with Indian alternatives such as HMEL B0155D and HMEL B0148D, IOCL 003DB52 sits between small-container and large-container blow moulding use cases. HMEL B0155D is more closely aligned with containers up to 20 litres, while HMEL B0148D is positioned for larger medium-to-large blow moulding applications such as tanks and bigger containers. The rationale behind 003DB52 is therefore clear: it is selected when processors need a medium blow moulding HDPE grade that bridges productivity, stiffness, impact performance, and broader application versatility including sheet extrusion.
