THPS(Tetrakis(hydroxymethyl)phosphonium sulfate) Application/Usage

THPS 75% is useful in a wide variety of industries including textile finishing and leather tannage,
oil and gas production and industrial water treatment. Its broad range of use is based on
multifunctional properties that make it an effective agent for flame retardancy, protein crosslinking,
and metal sequestration and deposit control.

THPS is a biocide effective against micropest in industrial cooling systems, oil field operations,
and paper-making industry. The advantage is it will soon degrade to a nontoxic substance immediately
after use,Also it can be applied to fabric coating, obviously improving flame retarding property.
