OPAL PP Opalene MH13A

OPAL PP Opalene MH13A is a polypropylene homopolymer injection moulding grade manufactured by ONGC Petro additions Limited (OPaL) under the OPaLene PP portfolio. This natural coloured PP grade is developed using Ineos gas phase polymerization technology and is designed for converters who need a reliable balance of higher flow, high stiffness, anti-static performance, and good dimensional stability.

MH13A is especially suited for moulders producing household articles, furniture components, and masterbatch, filler, and compound-based products where process consistency and part rigidity matter. Its anti-static property helps reduce dust attraction on finished parts, while its flow profile supports easier mould filling and stable production in regular injection moulding operations.

Manufacturer Snapshot

ONGC Petro additions Limited (OPaL) is one of India’s major petrochemical producers, supplying polypropylene grades for injection moulding, film, raffia, and specialty industrial applications. OPaLene PP grades are widely referenced in the Indian plastics market for dependable quality, application-focused grade design, and documentation aligned with food-contact and polymer compliance requirements.

Technical Insights and Data Sheet Highlights

OPAL PP Opalene MH13A has a melt flow index of 12 g/10 min, making it a practical high-flow PP homopolymer for injection moulding applications that require easier processing and efficient cavity filling. This flow level supports productivity in moulded parts with moderate wall sections while helping maintain cycle consistency.

The grade has a density of 0.90 g/cm³, which is standard for polypropylene homopolymer and useful for lightweight rigid applications. In mechanical performance, MH13A delivers 35 MPa tensile strength at yield, showing good load-bearing capability for rigid moulded products. Its 200% elongation at break adds a useful level of toughness beyond pure stiffness-focused performance.

For structural rigidity, the flexural modulus of 1400 MPa makes this grade suitable for furniture parts, household mouldings, and compound-based applications where shape retention is important. Its notched Izod impact strength of 25 J/m at 23°C supports everyday durability in end-use handling conditions. The Rockwell hardness of 95 on the R scale further reinforces its suitability for hard, rigid finished parts.

Thermally, MH13A offers a Vicat softening point of 150°C and heat deflection temperature of 100°C, helping moulded parts retain performance under moderate service heat. Combined with anti-static behavior and dimensional stability, these properties make the grade a strong choice for industrial moulders seeking a dependable high-stiffness PP injection grade.

Injection Moulding Performance

MH13A is designed for injection moulding processors that need a polypropylene grade with smoother flow and stable part geometry. The higher flow characteristic helps reduce mould filling issues and supports faster, more repeatable production, especially in consumer and industrial moulded articles.

Its anti-static property is a practical advantage in products exposed to dust-prone environments or where cleaner part surfaces are preferred. Combined with high stiffness, this makes MH13A relevant for moulders serving furniture, utility products, and compound-based downstream applications.

Applications

Household Articles

OPAL PP Opalene MH13A is well suited for household injection moulded products such as storage items, utility containers, kitchen-use articles, and daily-use rigid plastic components. Its high stiffness helps maintain product shape, while the anti-static property can improve surface cleanliness during storage, handling, and retail display.

Furniture Components

For plastic furniture and furniture-related moulded parts, MH13A offers the stiffness and dimensional stability needed for consistent shape retention and reliable structural feel. It is a suitable PP homopolymer grade for moulded chairs, stools, support parts, and rigid furniture accessories where processability and rigidity must work together.

Masterbatch, Filler and Compound Applications

MH13A is also used in masterbatch, filler, and compound applications where a stable polypropylene homopolymer base resin is required. Its flow profile supports easier dispersion and processing, while the stiffness profile makes it useful for compounders targeting rigid end-use formulations for injection moulding markets.

Compliance and Handling

This grade is aligned with IS 10910, IS 10909 positive list, and FDA CFR Title 21, 177.1520 requirements referenced for olefin polymers. For storage, the material should be kept in a dry, dust-free environment below 50°C and protected from direct sunlight and heat exposure to preserve processing consistency.

Comparable Alternatives and Grade Positioning

Within the OPaL range, OPAL PP Opalene MH13 is a close alternative for processors seeking a similar high stiffness injection moulding grade, but MH13A stands out because of its anti-static property. That makes MH13A a better fit where dust attraction on moulded parts is a concern or where cleaner surface behavior is preferred.

Compared with OPAL PP Opalene MH12N, MH13A is positioned as a high stiffness anti-static injection grade, while MH12N is typically considered where nucleation and related performance balance may be more relevant. Grade selection depends on whether the processor prioritizes anti-static behavior, stiffness profile, or specific moulding response.

Against Indian market alternatives such as IOCL Repol H110MA, MH13A remains competitive for moulders looking for a high-flow, rigid PP homopolymer for household and furniture applications. The rationale behind MH13A is clear: it is assigned for injection moulding segments that need stiffness, dimensional control, and anti-static benefit in one practical resin platform.
