Product Properties
1.UV-770 is recommended to be used in polypropylene; impact modified PP (TPO), EPDM, polystyrene, IPS, ABS, SAN, ASAand polyurethanes and is also effective in polyamides and polyacetals.
2.Benefit of using UV-770 is the high light-stabilizingperformance, particularly in Pp thick sections. lt has broad compatibility and can be easily dispersed. Compared toconventional UV-absorbers, the effectiveness of UV-770 is less dependent on the polymer’s thickness, For this reasonthe use of UV.770 also provides good light stability in articles with higher specific surface, e.g. films and tapes.
3. Use withSulfur-containing additives such DSTp or DLTP can have a negative influence on the effectiveness of UV-770.
