Silicon Dioxide, E551, CAS no.7631-86-9, white powder. Silicon dioxide (SiO2), also known as silica, is a natural compound made of two of the earth's most abundant materials: silicon (Si) and oxygen (O2). Silicon Dioxide is a common additive in the production of foods, where it is used primarily as a flow agent in powdered foods, or to absorb water in hygroscopic applications used in silica gel, control moisture levels to avoid prevent certain goods from going bad. It is often used in cheese, fat spreads, confectionery, dried vegetables, etc.

Titanium Dioxide

$150 - $250
MOQ: 10  Tons (UK)
Supplier From London, United Kingdom
 
Titanium dioxide is a white, odorless, and naturally occurring mineral compound that finds extensive use in various industries. It is most notably recognized as a white pigment in paints, coatings, plastics, and cosmetics due to its exceptional opacity and brightness. Titanium dioxide serves as an effective UV blocker in sunscreens, protecting the skin from harmful ultraviolet rays. In addition to its role in pigmentation and UV protection, it is employed as a catalyst in the chemical industry, and as a strengthening and opacifying agent in the food industry for items like confectionery, sauces, and toothpaste. Its versatility and ability to enhance color, protection, and strength make titanium dioxide an indispensable component in a wide range of everyday products.

Titanium dioxide, also known as Titanium (IV) or Titania, is a simple inorganic compound produced as a pure white powder with the molecular formula TiO2. Generally, it is available in two main crystal forms, which are rutile and anatase. Anatase is economical, easily dispersed in water-based systems, and a perfect opacifier. Untreated titanium dioxide (anatase) has TiO2 with a refractive index of 2.55. However, it is not commonly used in exterior (weather-exposed) paint applications except for highway paints.

Application: Paint and Coating Industry, Paper Industry, Cosmetics Industry, Food Industry, Plastic Industry etc.

Packing: 25 kg PP Bags
