In optical films, displays, LED lighting, and protective eyewear, UV and blue light are major causes of yellowing and aging over time.

With smartphones, tablets, vehicle displays, and LED lights everywhere, high-energy short-wave blue light (380–440 nm) is a major cause of eye strain and blurred vision.

Outdoor plastic products face constant aging from UV, heat, and moisture. OMNISTAB® LS3529 and LS3346 are high‑molecular‑weight hindered amine light stabilizers (HALS) that provide effective, long‑term protection for polyolefins and engineering plastics.

The highly reactive -NCO end rapidly undergoes addition reactions with hydroxyl, amino and thiol groups;

OMNISTAB® AN91PQ features a thermal decomposition temperature of around 300℃, far superior to conventional phosphite antioxidants.

Polymeric materials are highly susceptible to thermal degradation, yellowing, and mechanical property deterioration during high-temperature extrusion, high-speed injection molding, and prolonged service exposure.

Polymeric materials such as rubber, plastics, and elastomers have long permeated every aspect of production and daily life: synthetic rubber in shoe soles and anti-slip gloves provides comfort through its elasticity and wear resistance

During the use of polymer material, ultraviolet radiation silently breaks chemical bonds, causes yellowing, and leads to a deterioration in the materials’ mechanical properties.
