Product Safety
| Neuburg Siliceous Earth, extracted in the surrounding of Neuburg (Danube) is a natural combination of corpuscular, crypto-crystalline and amorphous silica and lamellar kaolinite: a loose mixture impossible to separate by physical methods. As a result of natural formation, the silica portion exhibits a round grain shape and consists of aggregated, crypto-crystalline primary particles of about 200 nm diameter, which are covered by amorphous silica opal like. This base material and a downstream thermal process lead to our calcined products.
The mineralogical uniqueness is the reason why Neuburg Siliceous Earth as "siliceous earth" the individual CAS No. 1020665-14-8 or Calcined Neuburg Siliceous Earth as "siliceous earth, calcined" the CAS No. 1214268-39-9 has been assigned. Moreover, their main components silica, kaolinite or calcined kaolinite are listed in all international product registers.
Which further applied formalities and directives are met by our products Sillitin/Sillikolloid/Aktisil and Ailfit/Aktifit, are summarized in pertaining synoptic charts.
Furthermore, we also want to point to the special REACh status of our products.
Worth mentioning in this context is the extremely low heavy metal content of Neuburg Siliceous Earth, which makes the material particularly suitable as a filler in products such as duroplast resins, reactive resins, rubber, cellophane, paper, cardboard, plastics dispersions, paints and coatings, if they are used in applications with food contact.
Additionally we confirm, that according to the Code of Federal Regulations Sillitin/Sillikolloid/Silfit and their surface treated types Aktisil/Aktifit can be used in elastomer applications.
In addition, other sensible application areas deserve mentioning such as food additives, self-medication products and cosmetics.
