1.THPS is a green and environmentally friendly quaternary phosphate fungicide. THPS has good water solubility, low freezing point, stable chemical properties, and long-term storage does not affect its quality. THPS is a new, excellent, efficient, broad-spectrum, low toxicity, low dose, low foaming, environmentally friendly fungicide with strong killing performance against bacteria and algae.

2.TPHS is also recognized internationally as a permanent flame retardant for pure cotton and polyester cotton fabrics. Due to its active hydroxymethyl group in its chemical structure, it has a reactive performance and can form high polymers with many substances such as amines and phenols. When used for olefin hindrance finishing, it can be shared with several resin initial reducers, giving cotton fabrics excellent flame retardant properties. When co treated with amines, due to the formation of a network structure with cellulose, methylene bonds and P-C-N bonds are formed, allowing flame retardant phosphorus to firmly adhere to the fibers. Moreover, the hydrolysis stability of P-C-N bonds is good, making the fabric resistant to alkaline washing. Pure cotton and polyester cotton fabrics treated with THPS still maintain their effective flame retardant properties after repeated washing.
