SYLYSIA® 350
Fuji Silysia Chemical USA Ltd. · SYLYSIA®
SYLYSIA® 350 is a 3.9 µm average particle size, non-treated, amorphous silica powder used as a matting agent, anti-blocking agent, and thickener. It delivers robust multifunctionality by reducing gloss, controlling ink transfer, and enhancing durability in various systems. SYLYSIA® 350 is especially well-suited for coatings, plastic films, adhesives, inks, and personal care formulations, due to its high oil absorption, low bulk density, and consistent particle size distribution.
- High porosity
- High chemical purity
- Compatible with multiple substrates
- Effective matting agent
- Enhanced surface properties
- Excellent adhesion
- Excellent pigment suspension
- Free flowing
- High thickening efficiency
