Plastic films and sheets are often rolled or piled after final processing. These films tend to adhere to each other at the many points of contact; a phenomenon called blocking. Such blocking problems occur in various kinds of plastic films, and can be minimized by introducing Sylysia into the formulation. High speed printing performance also suffers from similar problems. Wet ink printed on film, sheet, or paper transfers onto contact surfaces of other materials that are piled together. Sylysia has proven to be extremely effective in the prevention of ink transfer.
PHARMACEUTICALS & COSMETICS
Sylysia has been widely used as a powderizing agent or carrier for liquid medicines, fragrances, vitamin oil, and many other products. Other applications include improvement of powder fluidity in tablet production, use as a coating agent, and as an additive in ointments and milky lotions. Additional cosmetic applications include bath salts and related base cosmetics. Sylysia shows easy handling characteristics while stabilizing fragrance, hue, separation, adhesion, thickening, and fluidity. Sylysia is also used in cream products in the pharmaceutical and cosmetic industries. A tailored, micronized silica, SYLOPURE, is used as a thickening and abrasive agent in toothpastes.
ADHESION AND THICKENING
Sylysia is used in thinkening adhesive applications in resin, sealing components, along with many other products.
Sylysia can act to increase adhesive strength and durability. Sylysia can be used as an adhesive thickener to stabilize viscosity for longer shelf life. In addition to its adhesion and thickening effects, Sylysia effectively prevents stickiness and separation while providing emulsifying stability in these applications. These effects are stable regardless of environmental changes.
SENSITIZED PAPER APPICATIONS
Sylysia has been widely used to improve the printing performance of photographic printing onto Diaz sensitized paper, second traced paper, and photographic printing paper. Additionally, there are applications for information recording paper such as electrostatic recording paper, sensitized paper, and impact paper.
Sylysia is also applicable as a color-
These properties are precisely controlled to meet a wide variety of applications.
The superior Sylysia properties are applicable in several major industries

The chemical structure of SYLYSIA® is based on Silicon Dioxide (SiO2), one of the most abundant substances on earth.
The refractive index of SYLYSIA® is 1,46 similar to many polymer materials, which implies high transparency.
Synthetic micronized silica gel can be used in very different applications including matting agents in paint and coatings, film anti-
Silica grades having very fine particle sizes (3-
Silica grades with an average particle size between 6-
The adequate ratio particle size / film thickness is alsoaffected by the solid residue of the applied paint.
