PBTC (2-Phosphonobutane-1,2,4- Tricarboxylic Acid)
Product Overview:
PBTC is a phosphonate-based scale and corrosion inhibitor used extensively across industrial and oilfield water treatment applications. It is commonly employed in cooling towers, boilers, and industrial water treatment systems, where it binds calcium and magnesium ions to prevent scale buildup on heat transfer surfaces. Additionally, it serves as a corrosion inhibitor component that protects metal piping and equipment from oxidative and scale-related damage. PBTC is also utilized in midstream and upstream oilfield production water management programs to control scale in pipelines and process equipment. Furthermore, it finds applications in municipal water treatment systems requiring effective mineral scale control.
