Which are Ecologically friendly Ultraviolet ray blockers/absorbers/stabilizers that can be used in polymer?
Working on (reinforcement) bio-composite material using bamboo fibers & starch based DIY bio plastic from starch, glycerin, vinegar.
I wanted to incorporate UV Protection to my composite by adding UV protective additive in polymer mix.
I searched for regular additives (Benzophenone) that are added but I want to find if any Environmentally friendly UV stabilizers are available or can be extracted from natural sources to be used in bioplastic.
1-PABA (p-Amino benzoic acid) & 2-ZnO
Please do add your valued opinions.
