• Product description :

  UV-531 is a benzophenone type UV absorber for plastics and other organic polymers. Owing to its strong,broad UV absorption properties and excellent polymer compatibility.UV-531 exhibits very effective protection of polymers against UV light exposure. UV- 531 retards yellowing,embrittlement,and mechanical property degradation of the polymer when properly used.
