SYLYSIA® 370
Fuji Silysia Chemical USA Ltd. · SYLYSIA®
SYLYSIA® 370 is a 6.4 µm average particle size, non-treated, amorphous silica powder designed for use as a matting agent, anti-blocking additive, and viscosity stabilizer. It provides effective gloss control, improved print clarity, and strong anti-blocking performance in high-speed film and ink applications. SYLYSIA® 370 is especially suited for coatings, plastic films, inks, adhesives, and personal care products due to its high pore volume, low bulk density, and consistent particle size. The product ensures excellent dispersion, free flow, and functional consistency across diverse formulations.
