EPDM is generally used as a rubber material rather than a melt-processable thermoplastic resin. This grade is a black rEPDM flake made from car window seal feedstock and listed as PCR. The product sheet lists a 2 mm flake size, South Korean origin, and listed availability of 50 MT per month. Its listed applications include playground tracks, footpaths, and foam rubber.

Supplied in flake form rather than as melt-processable pellets, this rEPDM grade is evaluated in relation to its listed flake specification and the requirements of the intended rubber-based system. MFI is therefore not presented as a primary product specification.

Processing Performance and Application Potential

In bound rubber surfacing systems, rubber granules or flake are commonly combined with a polyurethane binder and installed as part of the finished surface. In a typical two-layer poured-in-place system, the base layer provides impact attenuation while the upper wear layer provides the exposed walking surface. Depending on the formulation and project requirements, EPDM rubber particles may be used in wear-layer or other bound-rubber systems.

The product sheet lists a 2 mm flake size for this black rEPDM flake. Flake size can be one of the factors affecting packing, surface texture, binder demand, and the final properties of a bound-rubber system, and the actual result depends on the formulation, binder ratio, compaction, and installation conditions.

Buyers may compare this grade with other available EPDM flake options based on size, feedstock, color, intended application, and binder-system requirements.

Material Data

Listed Availability from South Korea

The product sheet lists availability of 50 MT per month from South Korea. This rEPDM flake provides a PCR material option for playground tracks, footpaths, foam rubber, and other rubber-based applications where a black flake material is suitable.

A Rubber Flake Option to Evaluate

This grade is a black rEPDM flake listed at a 2mm flake size, classified as PCR with car window seal rubber as its feedstock, with 50 MT available per month and playground track, footpath, and foam rubber as its listed applications. As a rubber flake product rather than a melt-processable thermoplastic resin, this grade is described on the product sheet by its material type, feedstock, form, color, 2 mm flake size, listed applications, origin, and availability rather than by an MFI value.

Frequently Asked Questions

Why doesn't this grade have an MFI figure? This grade is supplied as rubber flake rather than a melt-processable thermoplastic pellet. EPDM is generally used as a rubber material rather than a melt-processable thermoplastic resin, so MFI is not used in the same way as it is for thermoplastic resins such as PP, PE, or ABS. The product sheet instead lists the material form, feedstock, color, 2 mm flake size, applications, origin, and availability. Density is not stated on the current product sheet — contact Regenport if a density value is required for your application.

What does the 2 mm flake size mean? The product sheet lists a 2 mm flake size for this grade. Flake size can be one of the factors affecting packing, surface texture, binder demand, and the final properties of a bound-rubber system, and the actual result depends on the formulation, binder ratio, compaction, and installation conditions used in a given surfacing system.

What should buyers consider about the car-window-seal feedstock? This grade is produced from recovered car window seal rubber, giving buyers an automotive-rubber feedstock option for PCR EPDM flake. This feedstock description distinguishes the material from tire-derived rubber crumb, and buyers should discuss compatibility, the intended binder system, and any contamination-control requirements with the supplier when evaluating this grade. The product sheet lists this feedstock alongside black flake form, a 2 mm flake size, and applications including playground tracks, footpaths, and foam rubber.
