It increases polymer IV in the melt phase, allowing for: • Improved rPET quality and performance • Higher target IV’s • Reduced solid state polymerization time • Increased productivity It also aids in the drive towards the circular economy and helps Brand Owners achieve sustainability targets through: • Reduced carbon emissions • Increased rPET content PCR rPET resin with • Reduced SSP or oven time • Reduced yellowing PCR rPET resin with INCREASED TARGET IV ColorMatrix rePrize allows for increased target IV and increased strength of the rPET material, enabling a wider range of product applications including carbonated soft drinks (CSD). ColorMatrix rePrize is a very reactive additive and any changes to the extruder temperatures and parameters will have an effect on melt viscosity of the polymer and also the finished article.

Since the FlexCart Micro has a smaller footprint for use in operations where space is limited, the metering system uses the smaller 10L (LN) polymer delivery pack. The FlexCart Micro unit, due to its smaller footprint and reduced throughput range, is designed to work with the LN molded polymer containers—specifically the 10-liter pack.

History PET is the most common thermoplastic polymer in the polyester family. It is the same polymer resin utilized in the plastic bottle industry.
