Use of THPS 75%
 
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.
 
Package
 
In 25kg, 250kg plastic drum, or 1000L IBC tote, total 19.6-20mt/20'FCL palletized.
