UVGuard™ZnO
Hybrid Nano-Spherical Silica + Nano platelets based Gas Barrier Additive for High-Performance WVTR and OTR in Films and Packaging.
UVGuard TM ZnO is an advanced Nano-dispersion that provides broad-spectrum UV shielding for polymers, ensuring long-term outdoor durability and high clarity. This stable dispersion uses Morpheon™ Nano-Material Synthesis and Dispersion Technology to create a uniform distribution of Nanoparticles (>150 nm) at very low loadings. In addition to its primary function of UV blocking, it also provides antimicrobial and photocatalytic benefits. UVGuard TM ZnO is highly compatible with a range of polymers, including PP, PE, PET, PC, as well as various coating applications.
Conventional Challenges & Our Breakthrough
| UV Protection Range | Conventional Organic UV Absorbers | Nano ZnO Dispersion |
|---|---|---|
| UVB (280–320 nm) | Effective | Highly effective |
| UVA (320–400 nm) | Limited protection, many absorbers drop efficiency | Broad, strong absorption across full UVA |
| Visible Light (400–700 nm) | May cause yellowing at high loadings | Maintains clarity and color neutrality |
| Infrared Stability | Can degrade under prolonged sunlight exposure | Inorganic, stable under prolonged UV/IR |
