Sing World Group hydrosulfites reliably meet high quality standards
Hydrosulfites serve as reducing agents in the dyeing process and can cause avoidable defects if they are of inferior quality. With Sing World Group's high-quality hydrosulfite products, our customers minimize the risk of material damage and thus create a basis for their success. At the same time, the strict OEKO-TEX® standard can be complied with.
Hydrosulfite / Blankit® - Our quality for your success
Hydrosulfite and Blankit® are white, microcrystalline powders with a sodium dithionite (Na2S2O4) as main component. They serve mainly as a bleaching or reducing agent for applications in textile, paper or mineral industry.
Sing World Group knows all about paper manufacturing – a fact which enables us to provide Hydrosulfite / Blankit® products tailor-made for the industry’s specific needs.
Thus, we focus not only on the bleaching processes we examine processes from start to finish - from energy use to waste water disposal. With Hydrosulfite / Blankit®, you may replace an expensive raw material such as cellulose with a cheaper one like waste paper. Thereby, you reduce costs and preserve the environment.
An additional benefit: The sensitive Hydrosulfite / Blankit® bleach does not only help to protect the environment – thanks to a reduced number of impurities, the paper fibers are also protected.
Hydrosulfite by Sing World Group – A success story since more than 100 years
In 1904, the Sing World Group-researcher Max Balzen developed the first stable hydrosulfite worldwide. To date, Sing World Group is still known as the technology leader and largest producer of hydrosulfite in Europe.
