MRPL PP Mangpol HR005T

MRPL PP Mangpol HR005T is a polypropylene homopolymer raffia grade manufactured by Mangalore Refinery and Petrochemicals Limited using solvent-free gas phase polymerization with Novolen Technology. It is designed for converters looking for a dependable PP raffia grade for high-speed extrusion lines, general-purpose wrapping, and packaging conversion where process consistency and balanced mechanical performance are critical.

Mangpol HR005T is positioned as a general-purpose raffia and wrapping grade within the MRPL polypropylene portfolio. For buyers searching MRPL PP Mangpol HR005T, HR005T PP raffia grade, Mangpol HR005T supplier, or polypropylene homopolymer for wrapping in India, this grade offers a practical combination of extrusion efficiency, low water carryover, and stable end-use performance.

About the Manufacturer

Mangalore Refinery and Petrochemicals Limited (MRPL) markets its polypropylene range under the Mangpol PP brand. Its 440 KTA Novolen gas-phase polypropylene plant uses Ziegler-Natta catalyst technology and is known for low gel content, smooth processing at high line speed, excellent lot-to-lot consistency, and strong organoleptic characteristics. This manufacturing profile supports HR005T’s positioning as a reliable raffia grade for converters that prioritize throughput, consistency, and process stability.

Technical Description and Performance Insights

MRPL PP Mangpol HR005T is engineered for extrusion-led raffia and wrapping applications where stable melt flow and line efficiency are important. Its melt flow index of 4.5 g/10 min at 230°C/2.16 kg gives it a slightly higher-flow profile than lower-MFI raffia grades, which can support smoother processing and improved throughput on high-speed lines.

The grade delivers tensile strength at yield of 34 MPa and tensile elongation at yield of 9 percent, making it suitable for applications where tapes and converted structures need a dependable balance of strength and controlled flexibility. A flexural modulus of 1400 MPa supports stiffness in converted packaging formats, while Izod impact strength of 30 J/m contributes to toughness during handling, winding, and downstream use.

From a thermal standpoint, HR005T offers a Vicat softening point of 150°C and heat deflection temperature of 90°C. These values support stable processing and practical dimensional performance in raffia and wrapping applications. The official positioning around excellent processability, low water carryover, and a strong tenacity-toughness balance makes HR005T relevant for processors comparing PP homopolymer raffia grades for high-speed extrusion.

Processing Guidance

MRPL recommends barrel temperatures of 220–280°C and die temperatures of 260–280°C for extrusion processing. Quench temperature is guided at 30–40°C, while oven temperature is recommended at 155–160°C. These conditions are important for converters seeking stable tape formation, controlled orientation, and efficient line performance in raffia and wrapping production.

Applications

General Purpose Raffia Extrusion

MRPL PP Mangpol HR005T is suitable for general-purpose raffia extrusion where processors need a polypropylene homopolymer grade that runs efficiently on high-speed lines. Its flow profile and processability make it useful for converters focused on stable output, consistent tape behavior, and practical production economics.

Wrapping and Packaging Conversion

HR005T is positioned for wrapping applications where smooth extrusion and balanced mechanical properties are important. In packaging conversion, this makes the grade relevant for manufacturers looking for a dependable PP raffia raw material that can support consistent processing and usable end-product toughness.

High-Speed Extrusion Lines

One of the key strengths of Mangpol HR005T is its suitability for high-speed extrusion. Converters operating faster lines often need a grade with controlled flow, low carryover, and stable processing behavior, and HR005T fits this requirement well within the general-purpose raffia segment.

Industrial Packaging Uses

Beyond wrapping, HR005T can be considered for broader industrial packaging applications where raffia-type conversion is needed. It is especially relevant for manufacturers seeking a PP homopolymer grade that balances throughput and mechanical reliability without moving into film-specific or injection-moulding resin categories.

General Conversion Applications

Because HR005T is positioned as a general-purpose grade, it can serve converters who need flexibility across wrapping and raffia-led packaging uses. This makes it a practical choice for buyers evaluating domestic polypropylene grades for stable supply, process consistency, and broad conversion relevance.

Comparable Alternatives

Within the MRPL portfolio, HR005T is positioned as a general-purpose raffia and wrapping grade, while HR003 is more specifically aligned with woven sacks, FIBC, monofilament, and leno bag applications. This means HR005T is better suited where converters want slightly higher flow and high-speed processing support, while HR003 is a more application-specific raffia grade for woven packaging structures.

Compared with MRPL film grades such as HF003 and HF010, HR005T is clearly not a film-focused resin. It is also distinct from injection moulding grades like HM012T and high-flow yarn or fibre grades such as HY035R and HY035UR. Its assigned grade logic is centered on extrusion-led raffia and wrapping applications rather than molding, film, or fibre production.

Against broader Indian market alternatives such as OPaL RH03 and Repol B210R-type raffia grades, HR005T competes as a PP homopolymer raffia grade for converters who value processability, throughput, and balanced tenacity and toughness. Its differentiation comes from MRPL’s Novolen technology platform, the official emphasis on low water carryover, and its suitability for high-speed extrusion lines.
