- Applications
RIASORB® UV-770DF is recommended to be used in polypropylene; impact modified PP (TPO), EPDM, polystyrene, IPS, ABS, SAN, ASA and polyurethanes and is also effective in polyamides and polyacetals. Benefit of using RIASORB® UV-770DF is the high light-stabilizing performance, particularly in PP thick sections. It has broad compatibility and can be easily dispersed. Compared to conventional UV-absorbers, the effectiveness of RIASORB® UV-770DF is less dependent on the polymer's thickness. For this reason, the use of RIASORB® UV-770DF also provides good light stability in articles with higher specific surface, e.g. films and tapes. Use with Sulfur-containing additives such DSTP or DLTP can have a negative influence on the effectiveness of RIASORB® UV-770DF
