UV Absorber are useful in Preventing the degradation of substrates by filtering out harmful UV radiation.
UV absorbers are used in all synthetic material such as Plastics which is made up of Polycarbonate (PC), Polyesters, Polyamide (PA), Polyethylene (PE), Polyethylene terephthalate (PET) and so on.
In the UV absorbers there are 3 types as below:
1. Benzophenone
2. Benzotriazole
3. Triazine
One of the primary concerns with benzotriazoles is their potential to act as endocrine disruptors. Benzotriazole is a compound that has been identified as a Substance of Very High Concern (SHVC).
Benzophenones are less expensive, but are under scrutiny by REACH.
That’s why Triazine better to use over benzotriazoles and benzophenones.
Triazine is a nitrogen-containing heterocyclic compound with a six-membered ring structure composed of three carbon atoms and three nitrogen atoms. It is a highly stable and versatile compound that finds use in a wide range of applications, including UV Absorbers for Polymer additives, Coating, Dyes and Textile, Flame Retardant, Healthcare and Personal care, Automotive Industry, Agro films, etc.
Triazine chemistry - known for best UV stability there is.
Here we present our Presentation on Triazine for better understanding, why Triazine better to use over benzotriazoles and benzophenones.
