Polypropylene (PP) is widely used in injection-molded parts and as a base resin in compounds where flow, color, and compatibility with additives or fillers need to be considered. This Regenport grade is a white PP pellet listed with diaper feedstock and classified as post-consumer recycled (PCR). The product card lists compounding and injection molding as applications and identifies GRS certification.

The listing reports a melt flow index (MFI) of 40 g/10 min and a density of 0.92 g/cm³. If measured under the commonly used PP condition of 230°C and 2.16 kg, an MFI of 40 g/10 min would generally indicate a relatively high-flow PP grade. This may support the filling of thin sections and longer flow paths in injection molding. However, the product card does not state the test temperature, load, or method, so the MFI condition should be confirmed before comparison with another virgin or recycled PP datasheet.

Processing Performance and Application Potential

The white color is notable because it leaves more flexibility than black or grey recycled PP. It can provide a lighter base for coloring or for parts where a neutral appearance is preferred.

The listed MFI of 40 g/10 min may support injection molding of thin sections and longer flow paths, subject to confirmation of the test condition. For compounding, MFI is only one part of the evaluation. Buyers should also consider compatibility with the intended base resin, fillers, additives, and final formulation, as well as the effect of additional thermal processing on the recycled resin.

The diaper feedstock also deserves closer review. Because the sheet classifies the grade as PCR, buyers should confirm the exact input, the cleaning and separation process, and the basis for the PCR classification. Since diapers contain multiple materials, it is also worth requesting ash, moisture, filtration, and odor information when evaluating a sample.

Material Data

Supply from South Korea and GRS Documentation

The listing shows 30 MT per month from South Korea. Availability from a recovered-material stream can depend on collection volume, reprocessing yield, existing contracted quantities, production scheduling, lot availability, and shipping lead time. Allocation against a given specification and delivery schedule should therefore be confirmed at the time of contracting rather than assumed from the listed figure.

GRS is the certification identified on the product card. Before making a formal recycled-content or certification claim, buyers should verify that the applicable certification covers the relevant material and production site. They should also request the relevant Scope Certificate, confirm the certificate’s validity dates, and obtain a Transaction Certificate for the specific shipment where required.

Buyers whose reporting depends on a verified recycled-content figure should confirm the recycled-content percentage and ensure that the certification documents correspond to the material being supplied.

A White, Relatively High-Flow PCR Option to Evaluate

This grade is a white rPP pellet listed at an MFI of 40 g/10 min and a density of 0.92 g/cm³. The product card classifies the grade as PCR, lists diaper feedstock, identifies GRS certification, states South Korean origin, and shows availability of 30 MT per month. Compounding and injection molding are the listed applications.

The white color and the listed flow value may make it worth evaluating for converters that need a light-colored recycled PP base, a relatively high-flow injection grade, or a recycled PP component for compounding. Final suitability should be assessed after the MFI condition, feedstock stage, separation process, lot consistency, odor, and relevant certification documentation have been confirmed.

Sample quantities may be available for trial. Share your target formulation or part requirements, target color, and expected volume, and we will confirm current lot data, MFI test conditions, ash and moisture figures, certificate scope, and lead time.

Frequently Asked Questions

What are the advantages of a white recycled PP pellet? A white pellet may provide a lighter base for coloring or for applications requiring a light or neutral appearance. Buyers should confirm the color source and lot-to-lot consistency.

Is MFI 40 g/10 min suitable for injection molding? If measured under the commonly used PP test condition, an MFI of 40 g/10 min would generally indicate relatively high flow and may support thin-section or longer-flow-path injection molding. Buyers should confirm the actual MFI test condition and evaluate the material in the intended mold and processing window.

What should buyers evaluate when using this rPP for compounding? Buyers should evaluate compatibility with the intended polymer system, fillers, additives, and target formulation. MFI, color, odor, moisture, ash, filtration, and the effect of additional thermal processing should also be considered during compounding trials.

What should buyers confirm about the diaper feedstock? Buyers should confirm the exact source of the feedstock and how it supports the PCR classification — for example, whether the input comes from used post-consumer hygiene products or another recovered stream. They should also request information on sorting, cleaning, residual non-PP content, ash, moisture, odor, and filtration.

What does the GRS certification cover? The product card identifies GRS certification, but buyers should verify the applicable Scope Certificate, certified site, validity dates, and shipment-specific documentation where required.
