Tetrakis(hydroxymethyl)phosphonium Chloride (THPC) Applications
Flame Retardants & Textile Auxiliaries
THPC, as well as THPS, are used in the flame-resistant fabric industry to improve the tear strength of cotton and other cellulosic fabrics.
THPC can be also used as tanning agents in the leather industry.
Oilfield Operations
THPC is an anti-microbial agent against SRB (Sulfate Reducing Bacteria) with minimum effects on the environment used in oilfield drilling and production applications. THPC 80% can be also used as an iron control chemistry to prevent iron sulfide scale common in the oil and gas industry.
Industrial and Commercial Water Treatment
Tetrakis Hydroxymethyl Phosphonium chloride (THPC) can be also used for the control of bacteria, algae, and fungi in industrial/commercial recirculating cooling water systems, in heat transfer water systems, and in industrial process water systems.
