Clariant introduces new liquid additive masterbatch in HiFormer family

摘要

CLARIANT, one of the world leaders in specialty chemicals, has announced the introduction of a new liquid additive masterbatch that minimizes yellowing and greying of PET (polyester terephthalate) polymers caused by the introduction of post-consumer-recycled resin (PCR). The new optical brightening products, which are part of the HiFormer family of liquid masterbatch solutions and application technology, can be used in a wide variety of PET resin grades and processes, including injection-blow molding, injection molding and extrusion. Typically, PET resins are used in bottles and formed-sheet packaging. The additive has received approval for food-contact applications from the U.S. Food & Drug Administration.
