product description

Product Description
UV Absorber UV-P CAS 2440-22-4 White Powder Chemical Auxiliary Agent for Plastic
Product Name: UV-Absorber
Chemical Name: 2-Hydroxy-4-Octyloxybenzophenone; Octabenzone
CAS No.: 1843-05-6
MF: C21H26O3
.Storage&Packing: Store in a sealed, dark can. Packed in 25kg fiber can, 20kg, 25kg carton.
UV-Absorber UV 531 (Benzophenone-3) is widely used in plastics and rubber to prevent UV-induced degradation. It effectively absorbs UV radiation (290-360 nm) and dissipates it as heat, protecting polymers from yellowing, embrittlement, and loss of mechanical properties. Commonly applied in polyolefins, PVC, coatings, and rubber products like automotive parts and outdoor materials, it enhances weatherability while maintaining material clarity.

Application
UV Absorber UV-P CAS 2440-22-4 White Powder Chemical Auxiliary Agent for Plastic
UV absorbers are widely used in plastics and rubber to enhance durability by preventing photodegradation caused by UV radiation. These additives absorb harmful UV rays and convert them into harmless heat, thereby reducing discoloration, brittleness, and mechanical property loss. Common types include benzophenones and benzotriazoles, which are effective in polyolefins, PVC, and coatings. In rubber applications, UV absorbers protect against cracking and surface degradation, extending the lifespan of products like tires, seals, and outdoor footwear. They are often combined with antioxidants for synergistic effects. Their versatility and efficiency make them essential in industries requiring long-term UV resistance, such as automotive, construction, and packaging.
