What Does HALS Stand For?

HALS stands for Hindered Amine Light Stabilizers

HALS, or Hindered Amine Light Stabilizers, are a class of chemical compounds used in various materials to enhance their resistance to photodegradation. They function by scavenging free radicals generated by UV exposure, thereby preventing damage to polymers and maintaining the integrity and longevity of products such as plastics, coatings, and agricultural films. HALS are widely utilized in industries where long-lasting durability against sunlight is crucial.
