TIANGANG Light stabilizers

light stabilizers are a group of additives that have been developed to minimise or prevent the damage to plastics caused by exposure to the enviromnmental parameters of light, heat and air. tiangang offers a complete range of light stabilizers:

• Benzophenones
• Benzotriazoles
• Hindered Amine Light Stabilizers (HALS)
• Inorganic

These light stabilizers provide protection from UV radiation by interfering with the physical and chemical processes of light-induced degradation according to different mechanisms.

The benzophenone and benzotriazole based products are termed 'UV Absorbers' and stabilize by 1.) preferential absorbtion of UV light and 2.) dissipating this harmful energy in a safe manner via stabilized excited states.
In general terms, stabilizers containing sterically hinderd amines, HALS are very efficient at scavenging free radicals and thus prevent these species from reacting and causing degradation of polymer chains
