Unique smell. Do not burn, slightly acidic, corrosive. Easy-to-biodegradable, environmentally friendly and fairly. THPS is an environmental friendly phosphate biocide and flame retardant, water-soluble products, low freezing point, the nature of the chemical stability, and stored for a long time does not affect its quality.

1. Agent for sewage treatment (biocide), in the following sectors are widely used :

1） Oil field operations

2） Paper making industry

3) Industrial cooling systems

It is a new, good, efficient, broad-spectrum, low toxicity, low-dose, low-foam, environment-friendly biocide, for a number of industrial process water used in its sulfate-reducing bacteria are particularly effective, the product also apply to the acidic or alkaline environment, have excellent stability and easy-to-biodegradable.

4）Other environmental protection industry

2. As flame retardants. After the deal with flame retardant textiles. For cotton or polyester-cotton fabric and other persistent flame-retardant treatment, fire-retardant treated fabric performance, feel good, wash-resistant, strong loss of a small tear does not affect the original fabric of the excellent performance.

 3. Synthetic intermediates
