Antioxidants
|
|
ADEKA PALMAROLE offers a full range of solid and liquid primary and secondary antioxidants. For PVC we recommend the following products.

Light Stabilizer
|
Light stabilisers 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. ADEKA-PALMAROLE offers a complete range of light stabilisers:
• Benzophenones
• Benzotriazoles
• Hindered Amine Light Stabilisers (HALS)
• Inorganic
These light stabilisers 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 stabilise by 1.) preferential absorbtion of UV light and 2.) dissipating this harmful energy in a safe manner via stabilised excited states.
In general terms, stabilisers 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. |

Phosphites
|
|
Phosphites are efficient decomposers of hydroperoxides that are formed during the autooxidation of polymers. Phosphites are especially used in melt processing where they are added in blends with hindered phenolic anti-oxidants. Such combinations are more effective than hindered phenol alone.
