Commonly known as Rongalite, this is a Technical Grade powerful reducing agent. It is highly stable at room temperature but releases sulfoxylate radicals at elevated temperatures, making it ideal for controlled reactions.
The product features high purity (min 98%) and is primarily used in discharge printing on textiles. It ensures sharp patterns and excellent color removal without damaging the integrity of the base fabric.
In the polymer industry, it acts as a redox catalyst in emulsion polymerization. It allows for the production of synthetic rubber and resins at lower temperatures, enhancing product quality and process efficiency.
SoleChem, an ISO 9001:2015 certified chemical supplier based in Türkiye, delivers Sodium Hydroxymethylsulfinate (CAS 149-44-0) to customers in more than 40 countries.
