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.
Guidelines for use Thick Sections UV Stabilization of HDPE, LLDPE, LDPE and PP 0.1-0.8%
Films UV Stabilization of LLDPE and PP 0.1-1.0%
Tapes UV Stabilization of PP and HDPE 0.1-0.8%
Fibers UV Stabilization of PP 0.1-1.0%
The presence of the UV-absorber is recommended in unpigmented or slightly pigmented articles or to improve the light fastness of certain organic pigments. The idiographic dosage should be based on fact.
