Usage: THPS is a biocide against microbe used in oil field operations, industrial cooling system, and paper manufacturing industry. It will rapidly degrade to a nontoxic substance immediately after use. Besides, it is a flame retardant used in fabric finishing industry. Treated with it, fabric will have flame retardant property permanently, and the intrinsic property of fabric will not be affected.
