BCPL PP Brahma-pol WH034N
BCPL PP Brahma-pol WH034N is a polypropylene homopolymer raffia grade manufactured by Brahmaputra Cracker and Polymer Limited using Novolen Gas Phase technology. Designed for stretched tape and yarn applications, this grade combines low water carry-over, good processability, and strong mechanical performance for woven sack and monofilament converters.
Brahma-pol WH034N is positioned in BCPL’s raffia and monofilament portfolio as a dependable low-MFI polypropylene homopolymer for tape extrusion and related downstream conversion. It is especially relevant for manufacturers that need stable tape formation, good tenacity, and efficient processing on raffia lines. BCPL, a GAIL group company, produces this grade through Novolen Gas Phase technology, supporting consistent polymer quality for industrial packaging and monofilament applications.
Technical Insights
BCPL WH034N typically offers a melt flow index of 3.4 g/10 min and density of 0.91 g/cm³, making it suitable for raffia tape extrusion where controlled flow and mechanical strength are important. Typical performance values include tensile strength at yield around 340 kg/cm², elongation at yield around 9%, flexural modulus near 15000 kg/cm², and Vicat softening point around 154°C. This profile supports a useful balance of stiffness, drawability, and thermal resistance for woven sack and yarn applications.
A major processing advantage of WH034N is its low water carry-over, which helps improve line stability and reduce processing interruptions. Combined with good processability, this makes the grade attractive for high-speed raffia operations where output consistency and tape quality are critical. The mechanical profile also supports durable finished structures in sacks, ropes, monofilament products, and selected thermoforming applications.
Applications
Woven Sacks
Brahma-pol WH034N is highly suitable for woven sacks used in cement, fertilizer, food grain, and sugar packaging. Its raffia-grade flow and mechanical strength help converters produce stretched tapes with the durability and consistency needed for heavy-duty industrial packaging applications.
Leno Bags
This grade is also relevant for leno bag production, especially in vegetable and agricultural packaging. Its processability supports stable tape extrusion and weaving performance, helping manufacturers create lightweight yet durable packaging structures for produce handling and transport.
Ropes and Monofilament
WH034N performs well in ropes and monofilament applications where strength, stiffness, and processing consistency matter. The grade’s homopolymer structure and raffia-oriented characteristics make it useful for converters producing industrial filament-based products that require dependable mechanical behavior.
Thermoforming Applications
In thermoforming, WH034N can be used where processors need a polypropylene homopolymer with good stiffness and thermal resistance. While it is primarily known for raffia and tape applications, its broader utility makes it relevant for selected thermoformed products depending on design and processing conditions.
Comparable Alternatives
Within the BCPL portfolio, WH034N is the key raffia and monofilament grade, while grades such as FH110N are positioned more toward film packaging applications. This makes WH034N the more suitable choice for stretched tape, woven sack, and yarn-oriented processing rather than tubular film conversion.
In the broader Indian market, WH034N can be compared with MRPL HR003, OPaL RH03, and Reliance Repol B210R type raffia grades. All are relevant for woven sacks and raffia tapes, but WH034N stands out for buyers specifically seeking BCPL-origin polypropylene with low water carry-over, good processability, and application alignment across woven sacks, leno bags, ropes, and monofilament.
