Nearly every plastic is prone to degradation when exposed to UV light leading to brittleness, discoloration and other product failures. Typically introduced at very low levels, UV stabilizing additives can be combined with a base polymer or prepared as a part of a masterbatch.

Amshield-A25 is a heavily loaded, efficient stabilizer against light-induced degradation of polyolefins. It also contains a primary and secondary antioxidant to help thermal degradation.
