Introduction:

Tetrahydroxymethylphosphorus sulfate (THPS) is mainly used as a bactericide and algicide in water treatment, oil field pipelines, fish farming, etc. It can be rapidly degraded into completely harmless substances after use, and is also commonly used in fabric flame retardant treatment, leather softening and Paper and other industries. Tetrahydroxymethylphosphorus sulfate is a green and environment-friendly Chemicalbook quaternary phosphate fungicide. The product has good water solubility, low freezing point, stable chemical properties, and long-term storage will not affect its quality. It is a new, excellent, high-efficiency, broad-spectrum, low-toxic, low-dose, low-foaming, environmentally friendly fungicide, which has strong killing performance against bacteria and algae.

 

Use: 

Tetrahydroxymethylphosphine sulfate is a green and environment-friendly quaternary phosphate fungicide, and it is also a permanent flame retardant for pure cotton and polyester-cotton fabrics internationally.

 

1. Tetrahydroxymethylphosphorus sulfate is mainly used as a biocide.

2. Widely used in water Chemicalbook treatment, oil field, paper making and other industries. Because its main advantage is that it can be quickly degraded into completely harmless substances after use, which greatly reduces the impact of this type of industry on the environment.

3. It can also be used as a permanent flame retardant for pure cotton and polyester-cotton fabrics.
