Description: THPS is a kind of environmental anti-microbial reagent. It is characterized by its low solidity point and fine stability. It can be reserved for long time and can easily dissolve in water. It is a kind of new environmental pesticide with high efficiency, low toxicity and low rudimental. It can kill germ and aquatic plants. In 1995, the EPA of the United States ratified it with zero toxicity and awarded it with US Green Chemical prize.

 

Feature：

THPS can degrade to a nontoxic substance immediately after use.And it is particularly effective against sulfate-reducing bacteria (SRB), which are often problematic in enhanced oil recovery operations like injection water treatment, top-side systems, pipeline protection and storage.

 

Application：

THPS is an environmentally friendly biocide applied in industrial cooling systems, oil field operations, and papermaking industry. THPS is also applied as flame retardant in cotton, dacron-cotton fibers

 

Package: 200kg plastic drum。
