Precipitated silica - special products for food industry
Glassven's products line offers a wide range of Special Precipitated Silicas used as free flowing, anti-caking, carrier and process aid with many fields of applications in the food industry,pharmaceuticals, nutraceuticals, flavors and fragrances, essential oils, among others.
PIROSIL® protects the particle's surface from the moisture, avoiding the caking and allowing the free flowing of the particles between them. Due to its porous structure can absorb large quantities of liquids and still remains as a free flow powder.
PIROSIL® Benefits：
● High chemical purity enabling them to be used as food additive for human consumption.
● Excellent optical whiteness.
● Absorbs up to three fimes its own weight and keep its original form.
● Its production process guarantees a product free of toxins.
● Does not modify the nutritional value of foods.
● Offers good compatibility with other ingredients.
● The amorphous structure of Precipitated Silicas make them safer to use than the natural crystalline forms.
● Combines high absorption capacity with high density, as a result very good flow properties.
● Improves the free flow properties of powders making them easy to manipulate, transport and use.
● Cost saving.
● Complies with the food industry standards and food safety certifications.

PIROSIL®PS-200
It is a Precipitated Silica widely used as free flowing and anti-caking agent,due to its reduced particle size and hygroscopic nature. It guarantees the flowabilily of the product and storage stability up to high environmental moisture conditions.
PIROSIL®PS-300
It is a Precipitated Silica specially designed to perform as free flowing agent, anti-caking and carrier due to its high absorption capacity. It has a very fine particle size (obtained by milling process), which enables it to be compatible with a wide products range, particulartly those that have been powdered.
