Additives to recycle polyesters
such as PET, PBT, PLA and polyamides
Polyesters, polyamides and polycarbonates suffer hydrolysis and thermal degradation during processing, that´s why when you buy a recycled grade, the viscosity is much lower than the one you find with a virgin grade.
If you have experienced problems when you try to extrude or inject recycled streams of polyesters, polyamides and polycarbonate, AddiCo additives can help!
Chain Extension in PET
Recycled PET untreated shows low and inconsistent viscosity
AddiCo 9000, 9050
or AddiCo 3910 (pellet)
PET + AddiCo (0.5%) recovers
its melt viscosity
Chain Extension in PBT
AddiCo 9000 and its masterbatch AddiCo 3910 are an excellent choice as chain extenders for PBT. They allow lower melt viscosity, improving processability of recycled streams.
Chain Extension in PLA
AddiCo 9000 and its masterbatch AddiCo 3910 are an excellent choice as chain extenders for aliphatic polyesters
Small concentrations of these additives allow the recovery of molecular weight and melt viscosity
