The area of silicate raw materials shows the whole fascinating range of the diverse, profitable use of Dorfner fillers. From the classics – paper, glass and ceramics, to building materials and construction chemicals. Discover the diversity.
The Dorfner family business has been mining kaolin, also known as china clay, since 1895. High-quality industrial minerals are used in industries such as paper, glass and ceramics and are even used in vaccine ampoules.
Advantages of our raw materials:
Our raw materials from our own deposits in Hirschau are purified using modern processes, which guarantees the best results and globally recognized quality.
Dorfner kaolins are known throughout the paper industry as high-quality fillers and outstanding coating kaolins. They are used in a wide variety of paper qualities in the premium quality segment.
Dorfner products for the paper industry are always the first choice when particularly high quality demands and special technical requirements are placed on the paper – also with regard to its printability, the print image to be achieved and its feel
Dorfner has been offering the glass industry a complete range of high-quality glass sands for more than 50 years. The consistently high quality of Dorfner products gives the glass industry the security of being able to reliably control its melting processes in the furnace. Whether flat glass, crystal glass or borosilicate glass. The narrow grain size range of Dorfner solutions allows them to be used in almost all standard melting units. You can also rely on this in medical applications.
From sanitary ceramics and wall and floor tiles to high-quality porcelain and sophisticated technical ceramics: the range of applications for Dorfner industrial minerals in the ceramics industry is enormous. The high purity and customizable fineness of the products guarantee low production costs and compliance with the highest production standards. Our ground ceramic kaolins, for example, are processed using a complex, multi-stage hydrocyclone classification process. Due to their high kaolinite content, they enable a pure white firing color.
Dorfner in construction chemicals:
Dorfner offers mineral fillers for various construction chemical products such as fillers, coatings, levelling, repairs, fixings, joints and sealants. These refined minerals improve the formulation and facilitate processing, whether pasty compounds or finished products for mixing on site.
