At a glance for your formula

PENPET Green supplies r-MEG as monoethylene glycol recovered as a co-product of chemical PET recycling. The supplier lists polyester production, automotive cooling and heat-transfer uses and describes it as chemically identical to virgin MEG. This is a recycled-feedstock sourcing claim, rather than proof that a particular batch meets polymer or coolant specifications. Purity, trace contaminants and recycled-content traceability should be qualified against the intended process.

Grade-specific screening values have not been recorded. Consult the selected supplier’s technical reference.

PENPET Green · Supplier-reported · Awaiting human review

Listed claims

  • Supplier reports
  • PET-recycling origin
  • chemical identity with virgin MEG.
  • Recylced

Suggested applications

  • PET and polyester production
  • Polyester fibres
  • Heating and cooling antifreeze
  • Solar-thermal heat-transfer fluids
  • Automotive coolants
  • Closed industrial cooling circuits

Sustainability highlights

  • Supplier reports recovery from PET depolymerisation
  • Recycling co-product origin
  • no numeric carbon saving adopted

Performance highlights

  • Supplier describes chemical equivalence to virgin MEG
  • Water-miscible hygroscopic liquid
  • exact purity specification on request

Grade scope & review questions

  • Supplier product page rechecked; applications are recommendations rather than independent validation.
  • Gap: Request current SDS/TDS, recycled-content chain of custody, purity, DEG, water, colour and metals. No lower-dose evidence.
  • CAS 107-21-1 identifies the underlying chemical. It does not establish commercial-grade purity, stabilizers, renewable origin or batch composition.

3 of 16 defined fields are recorded with a source. This measures structured information currently on this site, not the completeness of every linked PDF. Missing fields remain in the denominator.

Coverage is separate from scientific accuracy, human verification and EcoSafe assessment. Molecular fields may not apply to a grade or family; they are not filled from another material to increase its score.
