Sulphur chemicals

Sulphur chemicals – quality made in Germany and with passion and experience

Tradition: we have produced sulphur chemicals for more than 50 years now and our passion is a permanent motivating force for their development. Our customers love our reliability, experience and flexibility. Our products’ chemical purity and high quality play an important role for them.

Today, in an era of globalisation and fast-paced changes, trust and reliability are of huge importance and we provide all this to all our customers in various industries for fertilisers, food, wood-based materials, natural oil, leather, textiles, photo developers, feeds, drugs, metal and in the mining industry, paper production and water treatment.


Ammonium bisulphite is commonly used in the production of caramel colour and for other things, e.g. in industrial water treatment or for wood-based materials.


Ammonium thiosulphate is used in the production of fertilisers for various plants like rapeseed, maize or corn or for photo developers.


Sodium bisulphite is very versatile. It is used, for example, for the production of surfactants and pigments or water treatment in the leather and textile industry.

TIB® Thio TS

Sodium tetra sulphide is used in water treatment to precipitate heavy metals and in the petrochemical industry, to name but a few.

TIB® Thio Flakes

Sodium hydrogen sulphide is used in the mining industry, leather production and water treatment. Sodium sulphide accelerates the depilation and soaking processes in leather production.
