In the industrial landscape, the selection of materials is of param utmost importance. A material with excellent performance can provide reliable protection for numerous application scenarios. IOTA BJ550 Phenyl Silicone Oil, also known as Polymethylphenylsiloxane Polymer, is such a remarkable material.

Unique Composition and Basic Properties

IOTA BJ550 is a single - phenyl - component phenyl silicone oil belonging to the category of polymethylphenylsiloxane polymers. It boasts several impressive basic properties. In terms of appearance, it is a colorless and transparent liquid, giving an impression of purity and uniformity. Its specific gravity at 25℃/15.6℃ is 1.11, and its viscosity at 25℃ reaches 125 mm²/s. The viscosity - temperature coefficient is 0.79, indicating relatively stable viscosity with temperature changes, which ensures consistent performance across different temperature environments.

Outstanding Safety and Stability

Safety and stability are crucial criteria for evaluating a material. IOTA BJ550 has high flash and fire points, with a flash point of no less than 300℃ and a fire point greater than 343℃. Its auto - ignition temperature is 482℃. These high safety parameters mean it has good safety in high - temperature environments and is less likely to catch fire, significantly reducing the risk of fire accidents during use. Moreover, it has a low volatility, with only 2.1% volatility under conditions of 4 hours at 250℃, allowing it to maintain stable performance over an extended period. It also has excellent radiation resistance, with an anti - radiation value of 1.7×10⁸ rads, enabling it to work stably in radiation - exposed environments.

Wide Range of Applications

Thanks to its outstanding performance, IOTA BJ550 finds extensive applications in various fields. In hydraulic surge arresters and buffers, it can effectively play a role in shock absorption and motion damping. In hydraulic drive valves and instruments used in nuclear power plants, its radiation - resistant property ensures the normal operation of the equipment. Additionally, it can serve as a high - temperature heat carrier in applications requiring insulation, lubrication, damping, shock absorption, and dust prevention. It can also be used as the base oil for high - temperature lubricating oils and greases, providing reliable lubrication and protection for industrial equipment.

Good Compatibility and Functionality

IOTA BJ550 has inherent inertness. It does not corrode metals and has no adverse effects on the seals commonly used in pressure reducers, valves, and instruments, showing good compatibility with various equipment and components. Its relatively high compressibility makes it highly suitable for shock absorption and motion damping applications. Due to its good oxidation resistance and temperature resistance, it can be used for heat transfer, with a relatively constant thermal conductivity over a wide temperature range, meeting the heat - transfer requirements under different temperature conditions.
