Foam EVA and foam PVC are widely used in the soles of sports shoes and casual shoes because of their relatively light elasticity, good performance and strong flexibility.
Most of the foam soles are white.
What kind of optical brightener should be used for EVA foam shoe soles?
The soles often come into contact with soil, water, land and other scenes, so the optical brightener should be excellent in heat resistance, sun protection and oxidation resistance.
Most fluorescent whitening agents can hardly meet the requirements of foamed soles.
Optical brightener Oribrite KCB has a strong whitening effect. Its stability, migration resistance and weather resistance make Oribrite KCB the best choice for EVA foam materials.
