#783 is a synergistic mixture of #622 and #944. It is a versatile light stabilizer with outstanding extraction resistance, low gas fading, and low pigment interaction. #783 areas of application including polyolefins (PP,PE), olefin copolymers such as EVA as blends of polypropylene with elastomers. #783 is particularly well suited for LDPE, LLDPE, HDPE films, tapes and thick sections and for PP fibers and films. It is also the product of choice for thick sections where direct food contact approval is required.
