IOCL HDPE Propel 004DP44

IOCL HDPE Propel 004DP44 is a natural high density bimodal polyethylene grade developed by Indian Oil Corporation Limited for pressure pipe extrusion applications. Manufactured using LyondellBasell Hostalen Slurry Process technology, this grade is designed for pipe manufacturers looking for dependable processability, strong mechanical performance, and reliable hydrostatic strength in PE 80 pipe systems.

Indian Oil Corporation Limited is one of India’s leading petrochemical producers with a broad portfolio of HDPE and PP grades serving pipe, packaging, moulding, and industrial processing applications. Within the IOCL Propel HDPE range, 004DP44 is positioned as a PE 80 pressure pipe grade developed for water transportation, sprinkler irrigation, sewerage, and related pressure pipe applications. Its bimodal structure helps balance extrusion efficiency with long-term mechanical performance, making it relevant for processors who need both output consistency and dependable finished pipe quality.

Technical Specifications and Deep Technical Insights

IOCL HDPE Propel 004DP44 has a melt flow index of 0.45 g/10 min at 190°C/5 kg and a density of 0.945 g/cm³, giving it a processing and stiffness profile suitable for PE 80 pipe extrusion. This combination supports good melt behavior during extrusion while maintaining the structural properties expected in pressure pipe applications.

The grade delivers hardness of 61 Shore D, tensile strength at yield of 27 MPa, elongation at break above 600%, and flexural modulus of 800 MPa. It also demonstrates hydrostatic pressure test performance of 165 hours at 80°C and 4.6 MPa and 48 hours at 80°C and 4.9 MPa, along with ESCR above 1000 hours under F50 10% Igepal conditions. In addition, it offers a Vicat softening point of 126°C and oxidative induction time above 30 minutes. These values show that 004DP44 is not just easy to process, but also built for long-term field durability, crack resistance, and thermal stability.

A key technical advantage of 004DP44 is its bimodal molecular weight distribution, which helps pipe processors achieve stable extrusion and consistent pipe properties. For manufacturers, this matters because pipe grades must perform not only in laboratory testing but also during continuous production runs where melt strength, dimensional consistency, and long-term pressure performance all influence final product quality.

The recommended processing temperature range is 180 to 220°C. The material is supplied in 25 kg raffia bags and should be protected from direct sunlight and poor storage conditions to maintain resin quality before use.

Applications

Water Transportation Pipes

IOCL HDPE Propel 004DP44 is well suited for PE 80 pressure pipes used in water transportation systems. Its hydrostatic performance, mechanical strength, and extrusion stability make it suitable for water supply lines where processors need a reliable HDPE pipe grade for long service life and consistent manufacturing output.

Sprinkler Irrigation Pipes

For sprinkler irrigation pipe manufacturing, 004DP44 offers a practical balance of processability and durability. Agricultural and irrigation pipe producers benefit from a resin that can run efficiently on extrusion lines while still delivering the pressure performance and toughness required for field conditions.

Sewerage Pipes

In sewerage applications, this grade supports the production of durable HDPE pipes that need to withstand long-term use, handling stress, and environmental exposure. Its high ESCR performance is especially relevant where resistance to stress cracking contributes to better reliability in service.

General Pressure Pipe Applications

Beyond standard water and irrigation uses, 004DP44 is also relevant for general PE 80 pressure pipe applications where manufacturers require a dependable extrusion grade with proven hydrostatic test performance. It is a suitable choice for processors serving utility, infrastructure, and project-based pipe demand in the Indian market.

Comparable Alternatives

Within the Indian HDPE pipe resin market, IOCL 004DP44 competes with grades such as HMEL P0148D, GAIL P80, and OPaL P80. Based on the available technical positioning, 004DP44 stands out as an IOCL PE 80 grade with a density of 0.945 and MFI of 0.45, making it a practical option for processors who prioritize smoother extrusion behavior and dependable pressure pipe performance in PE 80 applications.

Compared with IOCL 002DP48, which is a PE 100 grade for higher pressure and more demanding long-term performance requirements, 004DP44 is the more appropriate choice where PE 80 classification is sufficient and the application is focused on water transportation, sprinkler irrigation, or sewerage systems. Compared with HMEL P0148D and other PE 80 alternatives, 004DP44 offers a clear value proposition through IOCL-backed Hostalen technology, strong ESCR performance, and verified hydrostatic test results. The rationale behind this grade assignment is straightforward: it is intended for pressure pipe manufacturers who need a PE 80 resin that combines processability, durability, and compliance-oriented performance.
