NGR PET improvement systems

The  market  introduction  of  P:REACT  was  world  premiere  at  the  NPE2015.  The  P:REACT  follows  the  design  principles  of  LSP  (Liquid  State Polycondensation)  and  considerably  improves  the  properties  of  PET. This system has received the FDA-Letter of Non-Objection for food-contact applications in 2013 and is suitable for bottle flakes, fibers, wovens, non-wovens, sheets, thermoform-skeletons, preforms, start-up lumps and trays.

The  decontamination  performance  is  extremely  effective,  as  carried  out  in  the  liquid  phase  of  PET.  The  cleaning  of  the  material  exceeds  limits  set  by  recognized food safety standards, but also effectively removes spin oil from fibers. The IV increase can be measured in approx. 0,01 dl/g/min.  

The  continuous  operation  of  P:REACT  provides  rPellets  within  a  narrow  IV-range,  suitable  for  usage  in  valuable  high  end  applications  (i.e.  fiber-spinning  or  sheet  extrusion).  Batch  related  IV-fluctuations  are  simply  designed out.  The favorable      conditions      inside      P:REACT (temperature/surface:volume  ratio  of  the  melt/high  performance  vacuum),  easily  initiates  the  post-condensation-process  of  PET.  This  results  in  IV  increase rates of some 0,01 dl/g/min. Faster reaction leads to faster results and  a  more  profitable  operation.  The  separation  of  harmful contaminants, as spin-oils or those components not desired for food contact, are  removed  by  high  performance  vacuum.  This  high  decontamination performance  allows  the  use  of  P:REACT  for  many  applications. Scientific, third party tests show, that harmful components in the PET-melt are easily and securely removed within P:REACT, ensuring highest safety standards for  100% food-contact.   

P:REACT  actively  controls  the  residue-time  of  the  PET-melt  inside  the  reactor  and  automatically  adjusts  the  machine  parameters  to  receive  the desired IV at a consistent level. The recycling of PET requires the material to be  melted.  P:REACT  uses  the  melt-energy  for  post-condensing  PET.  The reactor  itself  only  maintains  the  heat-level.   

To prepare the melt for the LSP process,NGR offers the following systems:  

P:REACT can also improve PET-melts coming from other extrusion-sources
