SantoRad™’s Polyphenyl Ethers (PPEs) are notably resistant to ionizing radiation, making them ideal for high-temperature, radiation-resistant fluids. Our range of PPE-based lubricants is specifically designed for machinery operating in environments with intense, short-wavelength ionizing radiation. Common lubricants tend to degrade under such conditions, as ionizing radiation—like gamma rays, x-rays, and charged subatomic particles -breaking the carbon-hydrogen bonds, forming structurally different, less effective molecules with increased viscosity. In contrast, polyphenyl ether-based lubricants retain their structural integrity even when exposed to ionizing radiation levels as high as 10^11 ergs/gram. This resilience prevents them from turning into viscous gels, a common issue with hydrocarbon-based lubricants.
