For procurement managers and R&D scientists in the chemical and industrial sectors, understanding the precise specifications of a chemical product is paramount. Tetrakis Hydroxymethyl Phosphonium Sulfate (THPS), a versatile biocide and flame retardant, is no exception. As a leading THPS manufacturer and supplier in China, we are committed to providing clear and comprehensive information to our clients. This guide delves into the key specifications of THPS 75%, helping you make informed purchasing decisions.

Product Name: Tetrakis Hydroxymethyl Phosphonium Sulfate (THPS)
CAS Number: 55566-30-8

Key Specifications:

• Appearance: The standard appearance for THPS 75% is typically described as a colorless to light yellow liquid. This visual characteristic is an initial indicator of product quality and consistency. Variations within this range are common and do not typically affect performance, but significant deviations may warrant further investigation.
• Assay (%): The minimum assay for THPS is ≥ 75%. This figure represents the concentration of active THPS in the solution, ensuring that you receive a product with the advertised potency for effective application in water treatment, oilfield operations, or textile treatments.
• Specific Gravity (25°C): The specific gravity usually falls within the range of 1.35-1.42 g/ml at 25°C. This property is important for density calculations in formulation and handling.
• Active Phosphorus (%): A key component of THPS's efficacy, the active phosphorus content is typically ≥ 11.0%. This parameter is critical for understanding the chemical's functional contribution in various applications.
• Viscosity (25°C): THPS 75% typically has a viscosity between 30-40 cps (or mPa.s) at 25°C. This moderate viscosity ensures ease of handling, pumping, and mixing in industrial settings.
• Iron (Fe) content (ppm): The presence of iron is often monitored in chemical products. For THPS, the iron content is specified as ≤ 20 ppm, indicating a low level of metallic impurities, which is crucial for many sensitive applications.
• pH: The pH of THPS 75% typically ranges from 2.5 to 5.5. This slightly acidic nature contributes to its stability and compatibility with many other chemicals.

Understanding these specifications is vital for users to ensure THPS performs optimally in their intended applications, whether it's microbial control in industrial water systems, corrosion prevention in oilfields, or imparting flame retardancy to textiles. As a reliable THPS manufacturer and supplier from China, we guarantee our products meet these rigorous standards.
