YK-783 is a synergistic mixture of YK-944 and YK-622. It shows outstanding extraction resistance, low gasfading and low pigment interaction and delivers excellent cost/performance benefit. YK-783 is particularly well suited for LDPE, LLDPE, HDPE films, tapes and thick sections and for PP in fibers and films. It also be used in polyolefins (PP, PE), olefin copolymers such as EVA as well as blends of polypropylene with elastomers.
