JLK supplies high quality, U.S. produced hydrophobic precipitated and fumed silica for a wide variety of applications and industries.

Our products are manufactured as single and multi-phase composites to enhance properties such as dispersion, stability, hydrophobicity and functionality. Due to their unique particle characteristics, and large surface area, our fumed silica provides superior performance and benefits for many types of consumer and industrial applications such as adhesives, plastics, sealants, coatings, inks, toner, cosmetics, inks, food additives, and defoamers. Our products are approved for use per under 21 CFR §§ 173, 175, and 176.

Precipitated Hydrophobic Silica

We supply treated silica at levels of hydrophobicity ranging from standard to very high. Our products have particle sizes ranging from 2-3 microns to 12 microns and Surface Areas ranging from 120-140 m2/gr to 80 m2/gr. Industrial, Food Grade and Kosher products are available.
