Description
THPS is a kind of environmentalanti-microbial reagent. It is characterized by its lowsolidity point
and fine stability. It can bereserved for long time and can easily dissolve in water. It is a kind of
new environmental pesticide withhigh efficiency, low toxicity and low rudimental. It can kill germ
and aquatic plants. In 1995, theEPA of the United Statesratified it with zero toxicity and awarded
it with US Green Chemicalprize.

Feature
THPS can degrade to a nontoxicsubstance immediately after use.And it is particularlyeffective
against sulfate-reducing bacteria(SRB), which are often problematic in enhanced oil recovery
operations like injection watertreatment, top-side systems, pipeline protectionand storage.
Application
THPS is an environmentallyfriendly biocide applied in industrial cooling systems, oil fieldoperations,
and papermaking industry. THPS isalso applied as flame retardant in cotton, dacron-cottonfibers.
