👉 The PD Fluid, or Poly-Dimethylsiloxane fluid, is a type of silicone-based lubricant primarily used in industrial and medical applications. It's known for its excellent thermal stability, low toxicity, and ability to maintain a consistent viscosity over a wide range of temperatures. PD Fluids are widely utilized in machine bearings, hydraulic systems, and medical devices due to their non-reactive nature, which prevents chemical degradation and ensures long-lasting performance. Their low surface tension also makes them ideal for applications requiring minimal friction, such as in microfluidic devices and precision instruments.
