Benzophenone and benzotriazole chemistries are traditional UV stabilizers, characterized as absorbers. The protection mechanism of UV absorbers is based on absorbing the harmful UV radiation then dissipating without leading to photo-oxidation (i.e. dissipation as heat). 3V Absorbers can be used in a variety of polymers, including polypropylene, polyethylene, polystyrene, nylon, PVC, PET and others, and can be used alone or in combination with other UV stabilizers, i.e. HALS.
Product category: Light stabilisers (s. UV stabilizers)
Hindered amine light stabilizers, or HALS, are used in many different applications to protect the plastic articles from degradation due to prolonged outdoor exposure. 3Vs portfolio of HALS includes monomeric, oligomeric and polymeric products, and low, high and ultra high molecular weight HALS. Our broad product offering allows for stabilization systems to be individually tailored for superior performance.
3V HALS can be used in a variety of polymers, including polypropylene, polyethylene, polystyrene, nylon, PVC, and others. HALS and can be used alone, in HALS combinations or with UV absorbers.
