ONGC Petro Additions Ltd. is a major Indian petrochemical manufacturer with an established polypropylene portfolio supported by official technical data sheets and food contact declarations. For buyers searching for OPAL PP Opalene MH13, MH13 PP injection molding grade, high stiffness polypropylene for household articles, or rigid packaging PP homopolymer India, this grade offers a practical balance of flow, stiffness, and molding efficiency for industrial converters.

Product Description

Opalene MH13 is developed for injection molders who need a polypropylene homopolymer grade that delivers structural rigidity without sacrificing processing ease. With a melt flow index of 13.5 g/10 min, MH13 sits in a balanced flow range that supports efficient mold filling while maintaining the stiffness needed for molded consumer and packaging parts.

The grade is especially relevant where manufacturers need repeatable part geometry, stable molding behavior, and dependable productivity on commercial injection molding lines. Its high stiffness profile, combined with good dimensional stability and faster molding cycle capability, makes MH13 a strong fit for processors producing household goods, rigid packaging components, and everyday consumer products where part consistency and production efficiency are both critical.

OPAL PP Opalene MH13 has a melt flow index of 13.5 g/10 min at 230°C/2.16 kg, giving it a balanced processing profile for injection molding applications that require good mold filling with controlled stiffness. The density of 0.90 g/cm³ is consistent with polypropylene homopolymer identity and supports its use as a rigid molding resin for packaging and consumer applications.

From a mechanical perspective, MH13 offers tensile strength at yield of 34 MPa, elongation at yield of 6%, flexural modulus of 1150 MPa, notched Izod impact strength of 20 J/m at 23°C, and Rockwell hardness of R95. This property combination gives molders a useful balance of rigidity, dimensional control, and practical part performance for structural molded products.

Thermally, MH13 shows a Vicat softening point of 150°C and heat deflection temperature of 100°C. These values support its suitability in molded applications where thermal resistance and dimensional stability matter during use and processing. The technical strength of MH13 lies in its ability to combine higher flow for easy processing with stiffness and cycle efficiency, making it a commercially strong choice for injection molders selecting a reliable PP homopolymer grade.

Applications

Household Articles

OPAL PP Opalene MH13 is well suited for household articles where manufacturers need a polypropylene homopolymer grade with good stiffness, dimensional stability, and dependable molding behavior. Its balanced flow profile helps support efficient production of molded items that need to retain shape and perform consistently in everyday use.

Consumer Products

For consumer products, MH13 offers a practical mix of rigidity, processability, and surface quality. This makes it relevant for converters producing molded parts that require repeatable geometry, clean finish, and efficient cycle performance. The grade is especially useful where production consistency and structural integrity are important to finished-product quality.

Rigid Packaging

MH13 is a strong option for rigid packaging applications where molders need a high stiffness PP homopolymer with easy processing and good dimensional control. Its flow behavior supports efficient cavity filling, while its stiffness profile helps maintain part shape and functionality in packaging components used at commercial scale.

General Injection Molding Use

Across the broader injection molding segment, MH13 fits buyers looking for a PP grade for household molded products, consumer goods, and rigid packaging containers. Its technical profile makes it especially relevant where molders want a reliable homopolymer resin with balanced flow, faster cycles, and stable part performance.

Comparable Alternatives and Grade Positioning

Within the OPaL portfolio, MH13 occupies a clear position as a high stiffness injection molding grade for household articles, consumer products, and rigid packaging. Compared with MH13A, MH13 is the standard version, while MH13A is more relevant when antistatic performance is specifically required. Buyers should choose based on whether the application needs base high-stiffness molding performance or added handling-related functionality.

Compared with MH12N, MH13 is a straightforward high stiffness injection molding grade, while MH12N is more differentiated by its nucleated and antistatic formulation. MH12N is better suited where faster crystallization and reduced dust attraction are important, whereas MH13 is a strong fit when the priority is balanced flow, stiffness, and general-purpose rigid molded part production.

Against lower-flow or impact-oriented alternatives such as MI03, MH13 is better aligned to rigid packaging and consumer molded parts rather than high-impact furniture applications. The rationale behind MH13 is clear: it is assigned as a polypropylene homopolymer grade for converters who need easy processing, high stiffness, dimensional stability, and faster molding cycles in mainstream injection molding operations.
