OPaL PPCP Opalene MI44N

OPaL Opalene MI44N is provisionally described as a nucleated polypropylene impact copolymer (PPCP) with an estimated melt flow index in the 40–50 g/10 min range. Produced by ONGC Petro additions Ltd (OPaL), MI44N is engineered for injection moulding and compounding applications requiring high flow, medium impact strength, and dimensional stability. While official TDS and database listings for MI44N are limited, its designation and MFI band suggest suitability for appliance parts, automotive components, thin-wall injection moulded products, and masterbatch compounding. MI44N is typically supplied as natural granules in 25 kg bags, aligning with industry packaging standards.

Functional Features

Opalene MI44N is designed for converters and OEMs seeking high-flow processability, nucleated crystallisation for low warpage, and a balanced mechanical profile. Its reactor-grade consistency (inferred from OPaL’s product line) supports efficient, reliable production and traceability for B2B buyers.

Applications & Industry Use Cases

Appliances & White Goods

MI44N is suitable for appliance housings, AC grills, washing machine internals, and other white goods components where high flow, dimensional stability, and moderate impact resistance are critical.

Automotive

Automotive compounders and OEMs may use MI44N for interior and exterior trims, non-structural parts, and compounds where a balance of stiffness and impact is required.

Thin-Wall Injection Moulding (TWIM)

The high MFI and nucleated structure support efficient thin-wall moulding of containers, tubs, and utility products, reducing cycle times and supporting complex geometries.

Compounding

As a base resin for filler and masterbatch compounding, MI44N’s processability and reactor-grade uniformity support efficient dispersion and consistent mechanical properties.

Performance Advantages

Compared to lower-MFI or non-nucleated PPCP, MI44N (provisionally) offers faster cycles, lower warpage, and superior thin-wall filling. Its technical profile is competitive with Repol B400MN (38 MFI), IOCL Propel 3400MN (40 MFI), and Haldia M340 (40 MFI) for thin-wall, appliance, and compounding uses.
