EVERSORB® 991 is an excellent light stabilizer, and especially suitable for polyolefin. e.g. automotive bumpers, fascia, garden furniture etc. Eversorb® 991 does not affect initial color of polyolefin, and prevents degradation of polyolefin from light and weather, especially for discoloration from sunlight. In general, Eversorb® 991 is recommended 0.2 to 1.0 wt. % based on polymer weight.

EVERSORB® SC3 is particularly effective in styrenic polymers such as PS, ABS, and SAN. It provides outstanding photo-stability under UV exposure by effectively retarding yellowing, preventing embrittlement, and preserving mechanical properties of the polymers.
