Vacuum-formed products is manufactured under know-how of Aug. RATH jun. AG, Austria. For production are used high-grade alumina-silica fibres, fillers and organic and inorganic binders. These products are chemically neutral and are resistant to most acids and alkalis, except hydrochloric acids, phosphoric acids and concentrated alkalis.
