SYLYSIA® 430
Fuji Silysia Chemical USA Ltd. · SYLYSIA®
SYLYSIA® 430 is a 4.1 µm average particle size, non-treated, amorphous silica powder designed for use as a matting agent, anti-blocking additive, and thickener. It is part of the SYLYSIA 400 series, known for its high-density and low-bulk density properties, making it particularly effective in resin-based and water-based coatings. SYLYSIA® 430 is also used in plastic films, adhesives, paper coatings, and personal care formulations. With high chemical purity, pore volume, and surface area, it offers enhanced flowability, durability, and viscosity control across a wide range of applications.
