LNO™ P pellets

1 of 3 products in this brand
LNO™ P pellets is Made from 100% post-consumer recycled PET, LNO™ p goes through a patented purification process which creates a food grade material. It can be blended with virgin resin at high levels to mimic virgin appearance, performance and cost. The process involves melting the flakes through a fine mesh filtration process to remove remaining contaminants such as aluminum, glass and label particles to minimize surface imperfections. LNO™ p is a high intrinsic viscosity resin which can also be used in non-food applications requiring those properties..

Technical Processing Information

Recommended Drying Procedures :PET is a very hygroscopic material which readily absorbs moisture when exposed to ambient air. PET which is not properly dried will result in a lower IV and loss of other important physical properties. At time of processing, the moisture in PET must be less than 50 ppm or 0.005% by weight. Dry thoroughly in a high heat regenerative–desiccant drying system. DO NOT remove dried material from the drying hopper or expose it to ambient conditions prior to processing. Rapid degradation will occur when hot, dry PET is exposed, even briefly, to ambient air.

Recommended Drying Parameters

  • Drying Time : 4-5 hours
  • Drying air temperature : 295-330º F.
  • Drying air dewpoint : -40º C. / F.
  • Drying air flow rate  :1 CFM per pound per hour processed

The drying temperature used should be kept as low as possible to minimize yellowing by oxidation during this portion of the process.

Material Handling :Phoenix RPET resin is produced from Recycled PET. It shows good material flow characteristics and blends well with major virgin PET resins. For best results blending should be done just prior to drying, and conveying blended materials long distances should be avoided, but Phoenix RPET resin can generally be handled as your virgin PET resin.

Processing Parameters :Phoenix RPET resin can be processed very easily over a wide range of conditions. Typically, processing temperatures range from 530-565º F. The main focus of processing should be to minimize process temperatures and melt residence times in an effort to maintain the molecular weight of the material and minimize any yellowing of the material during processing.

  • Use the lowest possible barrel-temperature profile that will produce a clear product. 
  • Minimize melt-residence time. 
  • Minimize the back pressure used in extrusion to reduce shearing of the material. 
  • Use the lowest possible hot runner and nozzle temperature that will produce a clear part. 
  • Use the lowest possible mold coolant temperature to promote part clarity
