Is HDPE UV stabilized?

UV stabilizers are an ultraviolet blocking agent that prevent resin breakdown by light sources such as the sun or lighting fixtures. HDPE resin is not naturally stabilized, however iPoly adds UV inhibitor components during their process, so the sheet is thoroughly stabilized inside and out. This means that the physical strengths of Sani-Armor sheet will not deteriorate when subjected to full sun or other UV light sources.
