Understanding PBTC·Na4 Specifications: Liquid vs. Powder for Your Application

PBTC·Na4 (2-Phosphonobutane-1,2,4-Tricarboxylic Acid Sodium Salt) is a cornerstone chemical for industrial water treatment, renowned for its excellent scale and corrosion inhibition properties. Available in both liquid and powder forms, understanding the distinct specifications of each is crucial for selecting the most appropriate product for your specific application. As a leading manufacturer and supplier in China, we provide detailed insights into these variations.

The primary PBTC·Na4 product typically comes in two main forms: a colorless to yellowish transparent liquid and a white crystal powder. Each form is engineered to meet different logistical, handling, and application requirements.

Liquid PBTC·Na4:

The liquid form, often supplied in 200kg drums or IBC totes, offers convenience in terms of handling and direct dosing into water systems. Its specifications typically include:

  • Active content (as PBTC, %): 30.0 min
  • Active content (as PBTC·Na4, %): 40.0 min
  • Density (20℃): 1.35 g/cm³ min
  • pH (1% water solution): 9.0-12.0

The liquid form is preferred for its ease of integration into automated dosing systems and its suitability for applications where precise concentration control is paramount. Its higher pH also makes it inherently alkaline, which can be beneficial in certain water treatment scenarios.

Powder PBTC·Na4:

The white crystal powder, typically packaged in 25kg bags or larger woven bags, offers advantages in terms of storage stability and transportation efficiency, especially for longer distances or where space is a consideration. Its specifications typically include:

  • Active content (as PBTC, %): 64.0 min
  • Active content (as PBTC·Na4, %): 85.0 min
  • Total phosphoric acid (PO4³⁻, %): 22.5 min
  • pH (1% water solution): 4.0-6.0
  • Fe, mg/L: 20.0 max

The higher active content in the powder form means less material is needed for equivalent treatment strength, potentially reducing transportation costs and storage footprint. The lower pH of the powder form is also a consideration for specific formulation needs. It's important to note that the solid form can be hygroscopic, requiring careful storage to prevent moisture absorption.

When you choose to buy PBTC·Na4 from a reputable China manufacturer, you gain access to products engineered for consistent quality and performance. Whether you require the readily soluble liquid or the concentrated powder, our offerings are designed to meet the rigorous demands of industrial water treatment. We encourage you to contact us to discuss your specific needs and obtain a quote for the most suitable PBTC·Na4 form for your application. Our expertise ensures you receive the right chemical solution for optimal results.
