HMEL HDPE Polysure R0151D

HMEL HDPE Polysure R0151D is a 1-hexene co-monomer based high density polyethylene developed by HPCL-Mittal Energy Limited under the Polysure HDPE portfolio for raffia tape extrusion. Produced using Advanced Dual Loop Slurry MarTECH technology, this grade is designed for converters who need excellent processability, low water carry over, good stretchability, resistance to fibrillation, and high tenacity tapes for woven fabric applications.

HPCL-Mittal Energy Limited is one of India’s major petrochemical manufacturers supplying polyethylene grades for film, pipe, blow moulding, and extrusion applications. Within the HMEL raffia portfolio, R0151D is positioned as a specialized HDPE raffia grade for stretched tape extrusion where tape quality, drawing behavior, and woven fabric performance are critical. It is especially relevant for manufacturers producing fertilizer bags, food grain bags, tarpaulin, wrapping fabric, and other woven sack or woven fabric products that require strong and consistent raffia tapes.

Technical Specifications and Deep Technical Insights

HMEL HDPE Polysure R0151D has a melt flow index of 0.85 g/10 min and a density of 0.952 g/cc, making it suitable for raffia tape extrusion where controlled flow, tape orientation, and woven fabric strength are important. This balance supports stable processing and helps converters produce stretched tapes with dependable performance during drawing and weaving.

The grade shows tensile strength at yield of 27 MPa, tensile strength at break of 35 MPa, and elongation at break above 800%, indicating a resin with strong ductility and useful tape-forming behavior. It also offers flexural modulus of 1200 MPa, notched Izod impact strength of 250 J/m, ESCR of 80 hours, Vicat softening point of 127°C, and heat deflection temperature of 70°C. These values support its use in woven applications where strength, stiffness balance, and durability matter.

A major technical advantage of R0151D is its low water carry over, which is important in raffia processing because it helps support more stable tape quality and smoother downstream conversion. The grade also offers good stretchability, which is essential for efficient tape drawing and orientation during raffia tape production.

Another important benefit is its resistance to fibrillation. In practical terms, this helps converters produce tapes with more uniform structure and better weaving performance. Combined with its ability to deliver high tenacity tapes, R0151D is well suited for woven sack and tarpaulin applications where tape strength and consistency directly affect final product quality.

Recommended barrel temperature is 190 to 240°C. For storage and handling, the material should be kept in a dry, dust-free environment below 50°C and protected from direct sunlight and heat exposure before processing.

Applications

Fertilizer Bags

HMEL HDPE Polysure R0151D is highly suitable for fertilizer bag production where woven sack manufacturers need strong raffia tapes, good drawing behavior, and dependable woven fabric quality. Its high tenacity and resistance to fibrillation make it a practical choice for bags that must handle filling, transport, and stacking conditions.

Food Grain Bags

For food grain bag applications, R0151D supports the production of stretched tapes that can be woven into durable sack structures. Its processability and tape performance help manufacturers maintain consistent bag quality for agricultural and bulk packaging use.

Tarpaulin

Tarpaulin applications require raffia tapes with good strength, stretchability, and weaving consistency. R0151D fits this requirement well, making it relevant for producers who need an HDPE raffia grade capable of supporting durable woven fabric for covering and protective sheet applications.

Wrapping Fabric

The grade is also suitable for wrapping fabric and other woven fabric applications where tape uniformity and tenacity are important. Its combination of processability, low water carry over, and fibrillation resistance helps converters achieve more consistent weaving performance.

Stretched Tapes for Woven Applications

R0151D is fundamentally designed for stretched tapes used in woven applications, making it a strong choice for raffia extrusion lines focused on tape quality and downstream weaving efficiency. This makes it relevant across industrial packaging, agricultural sacks, and woven fabric manufacturing segments.

Comparable Alternatives

Within the HMEL raffia portfolio, R0150S is another raffia and stretch tape grade used for woven sacks and tarpaulin applications, but R0151D is positioned more strongly where converters want low water carry over, good stretchability, fibrillation resistance, and high tenacity tape performance. For buyers comparing the two, R0151D offers a clearer fit for woven fabric applications where tape consistency and strength are key priorities.

Against comparable Indian raffia grades such as GAIL R53H002, IOCL R53H002, Reliance R53H002, and OPaL RH03, R0151D competes as a specialized HDPE raffia resin for fertilizer bags, food grain bags, tarpaulin, and wrapping fabric. The rationale behind this grade is straightforward: it is assigned where converters need a raffia tape extrusion grade that supports strong stretched tapes, efficient drawing, and reliable woven fabric performance rather than general extrusion use.
