👉 St-fluid, also known as synthetic fluid or Styrene Butadiene Rubber Fluid (SBRF), is a type of lubricant and sealant used in various industrial applications, particularly in automotive and machinery maintenance. It is a viscous fluid composed primarily of styrene butadiene rubber (SBR) polymers, which provide excellent resistance to wear, abrasion, and chemical degradation. St-fluid is widely used as a brake fluid in vehicles due to its ability to maintain low friction and high thermal stability, ensuring smooth braking performance. Additionally, it serves as a sealant in hydraulic systems and other mechanical applications, offering durability and resistance to environmental factors like UV light, temperature extremes, and contaminants.
