Tetrakis(hydroxymethyl)phosphonium sulfate

1.THPS 2.Transparent liquid 3.Assay:Min75% 4.As new environmental pesticide with high efficiency and low toxicity

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.
