For procurement managers and R&D scientists in the chemical industry, identifying reliable suppliers for key raw materials is crucial. Tris(2-butoxyethyl) phosphate (TBEP), with CAS number 78-51-3, is a versatile chemical used across various applications, from plastics and coatings to adhesives and textiles. This guide aims to provide essential information for buyers looking to purchase TBEP, emphasizing quality, specifications, and the advantages of sourcing from reputable manufacturers, particularly those based in China.

Understanding Tris(2-butoxyethyl) Phosphate (TBEP)

TBEP is a phosphate ester characterized by its clear, slightly yellow liquid appearance. Its primary functions include acting as a plasticizer, imparting flexibility and improving low-temperature performance in polymers, and serving as a flame retardant, enhancing the fire safety of materials. Its excellent solubility in most organic liquids and moderate solubility in water make it adaptable to various formulation needs.

Key Specifications and Quality Considerations

When sourcing TBEP, buyers should pay close attention to several key specifications to ensure suitability for their applications:

  • Appearance: Typically described as a colorless or light yellow transparent liquid. Deviations from this may indicate impurities.
  • Purity: While enterprise standards can vary, a high purity level (e.g., >95% or enterprise standard) is generally desired for consistent performance.
  • Acid Value: A low acid value (e.g., ≤0.1 mg KOH/g) is important, as high acidity can affect stability and compatibility in certain formulations.
  • Color (APHA): A low APHA color value (e.g., ≤50) indicates a purer product.
  • Moisture Content: Low moisture content (e.g., <0.2%) is crucial for many chemical processes to prevent unwanted reactions.
  • Specific Gravity: Typically around 1.017-1.023 at 20/25°C.
  • Boiling Point: Around 225°C, but values may vary slightly depending on pressure.

As a buyer, always request a Certificate of Analysis (CoA) from your supplier to verify these specifications. If you need to buy Tris(2-butoxyethyl) phosphate for critical applications, understanding these parameters is essential.

Common Industrial Applications

TBEP finds extensive use in several industrial sectors:

  • Plastics and Polymers: Used as a flame-retardant plasticizer for polyurethane resin, cellulose acetate, polyvinyl alcohol, and acrylic plastics, improving flexibility and fire resistance.
  • Coatings and Adhesives: Acts as a coalescing solvent and plasticizer in polishes, paints, and adhesives.
  • Textiles: Employed as a defoamer and leveling agent in various textile processing applications.
  • Detergents: Used as an antifoaming agent in cleaning formulations.

Sourcing TBEP from China: Advantages and Considerations

China has emerged as a leading global supplier of specialty chemicals, including TBEP. Sourcing from Chinese manufacturers offers several advantages:

  • Cost-Effectiveness: Competitive manufacturing costs often translate into more affordable pricing, especially for bulk orders.
  • Volume Capacity: Chinese manufacturers typically have large-scale production capabilities to meet high-volume demands.
  • Diverse Product Offerings: Many suppliers offer a range of related chemicals, simplifying procurement for multiple needs.

When selecting a supplier, look for companies with established quality management systems, clear communication channels, and a proven track record. Companies that can provide detailed technical data sheets (TDS) and safety data sheets (SDS) are also preferable.
