四羟甲基氯化磷(THPC)/Tetrahydroxymethyl Phosphorus Chloride (THPC)
Tetrahydroxymethyl Phosphorus Chloride (THPC)
English name: Tetrakis Hydroxymethyl
PhosphoniumChloride/TetramethylolphosphoniumChloride(THPC)
Tetrakis(hydroxymethyl)phosphorus chloride (THPC) is mainly used for flame retardant treatment of fabrics, and also used as an additive flame retardant for plastics and paper products. It can also be used in organic synthesis. It is widely used as an efficient environmentally friendly flame retardant in printing and dyeing enterprises in Europe and my country in Henan, Hebei, Sichuan and other places. After THPC is added with urea, tetrakis(hydroxymethyl)phosphorus chlorinated urea (THPC-U) with a content of >70% can be synthesized. This new flame retardant can greatly increase the washing durability of pure cotton textiles, and make cotton fabrics still Maintains good softness and feel, the tearing force index remains unchanged, THPC-U maintains the original performance of the fabric to the limit.

Purpose
(1) Flame retardant for textile post-treatment, used for durable flame retardant treatment of pure cotton or polyester cotton and other fabrics. The treated fabric has excellent flame retardant performance, good hand feeling, washing resistance, low tear strength loss, and no Affect the original excellent properties of the fabric.
(2) Additive flame retardant for plastics and paper products.
