A Colorless and Consistent Fluid

At first glance, IOTA BJ550 is a colorless liquid with a specific gravity of 1.068 at 25°C/15.6°C. However, its true value lies in its meticulously engineered physical properties. With a low viscosity of 125mm²/sec at 25°C, it flows easily, facilitating rapid heat exchange and efficient lubrication. The fluid also exhibits a surface tension of 25 mN/m at 25°C, allowing it to wet surfaces effectively and penetrate microscopic gaps in mechanical assemblies.

Thermal and Oxidative Resilience

The molecular structure of Polyphenylmethyldimethylsiloxane grants IOTA BJ550 its remarkable stability. It possesses a high flash point of 300°C and a freeze point of -50°C, covering an extraordinary temperature spectrum. More importantly, its good oxidation and gumming resistance ensures that the fluid does not degrade into acidic byproducts or thick sludge when exposed to heat and oxygen. The viscosity stability remains below 5%, proving that the fluid maintains its original characteristics even after prolonged thermal stress.

Optical and Storage Specifications

For applications requiring optical clarity, IOTA BJ550 has a refractive index of 1.49-1.50 at 25°C. Proper storage is essential to maintain these premium characteristics. When kept in original, unopened containers at temperatures of 60°C or below, the product guarantees a usable life of 60 months from the date of production. It is important to note that while this fluid is a marvel of industrial chemistry, it is neither tested nor represented as suitable for medical or pharmaceutical uses, strictly adhering to industrial safety and regulatory standards.
