FUNCTIONAL,
NOT JUST GREEN
Chosen for what it does, not only for being green.
The strength of SHELLIE
Our own particle processing technology gives SHELLIE physical properties that resist cracking, even at 70–80% eggshell loading.
We treat the surface of each eggshell-based particle so it blends into plastics and paints.
Our own particle shape and size improve dispersion in plastics, coatings and fibres.
Antibacterial and antiviral performance confirmed by a third-party lab
Activity values. Tested on PP plates with 10% SHELLIE Powder. A value of 2.0 or more means effective.
