Kaolin contributes to the mechanical and thermal properties, while feldspars support the melting process and help create a homogeneous material structure. Thanks to its high silica content, quartz influences the chemical resistance and other properties of the resulting products. Combining these raw materials makes it possible to produce glass fibres with the required strength and durability. The consistent quality of our raw materials, together with expert know-how and reliable deliveries, forms the basis of long-term cooperation with our customers in this demanding industrial sector.
