Light Stabilizers

Your location: Home  > Products & Solutions  > Light Stabilizers


Light stabilizer is a polymer (e.g., plastics, rubber, paint, synthetic fibers) additive, which can block or absorb ultraviolet energy, quenching singlet oxygen and make hydrogen peroxide decomposed into non-active substances For the polymers under light radiation, light stabilizer can eliminate or mitigate the possibility of photochemical reaction, prevent or delay the process of photoaging, so as to prolong the service life of polymer products purpose. At present, the most widely used light stabilizer is hindered light stabilizers (HALS) and ultraviolet absorber (UVA).

 

HALS: Hindered amine light stabilizer (HALS) is a kind of organic Amine having a steric hindrance of the compounds. Added to plastics and other materials, it can inhibit or slow the speed of light degradation of the polymer.
