CLARIFEX clarifiers effectively reduce haze and yellowness, imparting a clearer, whiter appearance to polypropylene homopolymers, ethylene-propylenecopolymers, and LLDPE.
Even after repeated heat histories, as with regrind, CLARIFEX clarifers do not yellow or darken like many other nucleating agents.
Unpleasant odor and taste problems are eliminated as well, serving to increase the marketability of your molded part or its contents. ,
Less apparent, yet crucial to consumers, is that CLARIFEX clarifiers offer the broadest FDA clearance for retortable food applications.
