POM Black Granule: Black Recycled POM Granules

Actual per-batch values are available through our sales team.

• POM type (homopolymer or copolymer)

  Affects heat stability, chemical resistance, and processing settings.

• MFI

  Usually tested at 190 °C / 2.16 kg; indicates how easily the material flows in injection or extrusion.

• PVC and halogenated plastic contamination

  Critical: even a small amount can trigger POM decomposition in the barrel and release formaldehyde.

• Other contaminants (nylon, PP, metal)

  Other plastics and metal lower the quality of the processed material and can damage machines.

• Formaldehyde odor

  A strong odor in the material can indicate it has decomposed from overheating.

• Regrind size and dust

  Affects feeding into the machine and the uniformity of melting.

• Color consistency and black specks

  Important for products with visible surfaces.

Store covered in a dry place and dry if needed according to your machine or supplier recommendations. Do not process too hot or for too long in the barrel, because POM can decompose and release formaldehyde. Keep it away from PVC, purge the machine when changing materials, and ensure good ventilation.
