What is N,N-Diethylhydroxylamine in plastic?

In the plastics industry, DEHA (N,N-diethylhydroxylamine) is primarily used as a stabilizer, particularly as an antioxidant and light stabilizer.

During production, processing, and use, plastics are exposed to factors such as heat, oxygen, and light, which can lead to oxidative degradation, causing them to become brittle, discolor, and lose strength. DEHA can capture free radicals and inhibit the occurrence and progression of oxidative reactions, thereby slowing the aging process and extending the lifespan of plastics.

Ultraviolet radiation is a major factor in plastic aging. DEHA absorbs UV rays and converts them into harmless heat, thereby protecting plastics from the damaging effects of UV radiation, preventing yellowing, cracking, and performance degradation.
