Avient (formerly PolyOne) introduces ColorMatrix™ AAzure™ Acetaldehyde Control Additive. The new grade is a process aid for PET and recycled PET (rPET) preforms with added acetaldehyde (AA) control capabilities. It is a patented liquid formulation that can reduce AA by up to 80 percent in the preform and helps to counter off-taste in bottled contents.
Technology to Overcome rPET Usage Issues
The increased use of rPET in PET bottles can lead to increased AA levels and can compromise bottle mechanical strength and create blowouts. This reduces productivity and increases scrap rates. The new technology helps to overcome these issues so that higher levels of rPET can be used.
The product can be combined with recycle-friendly toners to offset the yellowing common with increased rPET content. One more benefit is the reduction in the energy required to heat preforms, which fosters roughly 25 percent lower carbon emissions.
ColorMatrix AAzure enables increased levels of rPET usage in plastic products without any reduction in performance or quality.
