OPAL PP Opalene RH38

OPAL PP Opalene RH38 is a polypropylene homopolymer fiber grade manufactured by ONGC Petro Additions Ltd. under the OPaLene PP brand. Produced using Ineos gas phase polymerization technology, this high flow grade is positioned for fine denier fibers, spun bond non-woven, and high speed spinning applications where converters need stable processing, reliable resin uniformity, and commercially consistent output.

ONGC Petro Additions Ltd. is one of India’s recognized petrochemical manufacturers with an established polypropylene portfolio supported by official technical data sheets and food contact declarations. For buyers searching for OPAL RH38 supplier India, RH38 PP spunbond grade, or high flow polypropylene homopolymer for nonwoven production, this grade offers a strong combination of processability, fiber-oriented flow behavior, and compliance-backed credibility.

Product Description

Opalene RH38 is developed for processors operating high-speed fiber and nonwoven lines where melt flow, throughput, and consistency directly affect production efficiency. With a melt flow index of 38 g/10 min, RH38 sits in the higher-flow segment of polypropylene homopolymer grades and is especially relevant for spun bond nonwoven structures and fine denier fiber production where smooth extrusion and stable web formation are critical.

The grade is designed to support manufacturers who need a PP homopolymer that can perform reliably under demanding spinning conditions without compromising resin consistency. In practical terms, RH38 is best suited for applications where output speed, finer fiber formation, and dependable line behavior matter more than general-purpose molding versatility. This makes it a focused technical choice for nonwoven and fiber processors looking for a specialized raw material rather than a commodity polypropylene grade.

OPAL PP Opalene RH38 has a melt flow index of 38 g/10 min, which places it in a distinctly high-flow category for polypropylene homopolymer fiber grades. This higher MFI profile makes the material especially suitable for high speed spinning and spun bond nonwoven production, where controlled melt behavior and efficient conversion are essential for maintaining productivity and product consistency.

The density of 0.90 g/cm³ aligns with standard polypropylene homopolymer material identity, while the broader mechanical and thermal profile supports its role in fine denier fiber and nonwoven applications. For manufacturers evaluating PP grades, the technical importance of RH38 lies in how its flow behavior supports finer fiber formation, more efficient line speeds, and smoother processing across demanding nonwoven operations.

From a buyer’s perspective, RH38 should be understood as a specialized high-flow PP homopolymer rather than a general-purpose resin. Its technical strength is in supporting applications where throughput, fiber fineness, and process stability are commercially critical. That makes it particularly relevant for processors selecting raw material for spun bond nonwoven production, high speed spinning lines, and fine denier fiber output.

Applications

Spun Bond Nonwoven

OPAL PP Opalene RH38 is strongly positioned for spun bond non-woven applications where processors need a high flow polypropylene homopolymer capable of supporting stable web formation and efficient line performance. Its flow profile makes it suitable for nonwoven manufacturers serving hygiene, medical, industrial, packaging, and filtration-related segments where consistency and throughput are key purchasing factors.

Fine Denier Fibers

For fine denier fiber production, RH38 offers the kind of high-flow behavior that helps processors target finer output with more dependable conversion performance. This makes it relevant in applications where fiber fineness, uniformity, and smooth processing are important to downstream quality and commercial acceptance.

High Speed Spinning

RH38 is also a suitable choice for high speed spinning environments where ordinary PP grades may not deliver the same level of flow efficiency. In these operations, the grade supports faster processing conditions and helps manufacturers maintain line stability while targeting high-output production schedules.

Fiber and Nonwoven Manufacturing

Across the broader fiber and nonwoven sector, RH38 fits buyers looking for a PP grade for spunbond nonwoven, polypropylene for fine denier fibers, and high flow PP homopolymer for industrial textile conversion. Its application profile makes it especially useful where production speed, resin consistency, and process control are central to grade selection.

Comparable Alternatives

Within the OPaL portfolio, RH38 is the more aggressive high-flow option when compared with RH25X and RH22U. RH25X, with its 25 MFI positioning, is better suited for multi filament yarns, fine denier staple fibers, and spun bond non-woven applications where a more balanced fiber-grade profile is preferred. RH38, by contrast, is the stronger choice when higher flow and high speed spinning performance are the main requirements.

Compared with RH22U, RH38 is less about UV stabilization and anti-gas fading and more about processing speed and spunbond-oriented conversion. RH22U is broader in its positioning across continuous filament, staple fibers, and selected molded applications, while RH38 is more tightly aligned to processors prioritizing fine denier fibers and high-speed nonwoven production.

The rationale behind RH38 is clear: it is assigned as a high flow polypropylene homopolymer for converters who need faster spinning, finer fiber capability, and stronger suitability for spun bond nonwoven manufacturing. For Indian buyers comparing OPaL grades, RH38 should be selected when the application is driven by line speed and nonwoven efficiency rather than broader fiber versatility or stabilization-focused performance.
