In the vast world of silicone oils, IOTA BJ510 polymethylphenylsiloxane stands out as a remarkable product. It belongs to the category of methylphenyl polysiloxane polymers and is a monophenyl - component phenyl silicone oil. This unique chemical structure endows it with a series of excellent properties.
IOTA BJ510 exhibits excellent thermal stability. It can maintain stable performance even under high - temperature conditions, without undergoing decomposition or deterioration. Its high flash point and non - flammability ensure high safety during use, significantly reducing the risk of fire. Additionally, its low volatility minimizes performance degradation and losses due to evaporation during long - term use or storage.
The inherent inertness of IOTA BJ510 makes it an ideal choice for many applications. It does not corrode metals and has no adverse effects on the seals commonly used in pressure reducers, valves, and instruments, thereby extending the service life of equipment. Its relatively high compressibility makes it well - suited for shock absorption and motion damping applications, effectively absorbing and dispersing energy to reduce the impact of vibrations and shocks on equipment.
With good oxidation resistance and temperature resistance, IOTA BJ510 can be used for heat transfer. Its thermal conductivity remains relatively constant over a wide temperature range, ensuring efficient and stable heat transfer. Moreover, it has excellent radiation resistance, with a radiation resistance value of 1.7×10⁸ rads, making it suitable for applications in radiation - exposed environments.
The technical specifications of IOTA BJ510 are precisely defined. It appears as a colorless and transparent liquid. Its specific gravity at 25℃/15.6℃ ranges from 0.985 to 1.090, and its viscosity at 25℃ is between 50 and 3000 mm²/s, with a viscosity - temperature coefficient of 0.655. The flash point is ≥274℃, the ignition point is >343℃, and the auto - ignition temperature is 482℃. The pour point is - 57℃, indicating good low - temperature fluidity. The specific heat at 100℃ is 0.405, and the thermal conductivity at 50℃ is 0.00036 g - cal/cm² - sec - ℃. The volatility (%, 4 hr, 250℃) is 2.5. The compression rates and bulk moduli at different pressures (5000 psi and 20000 psi) are also clearly specified, enabling it to meet the requirements of various complex working conditions.
IOTA BJ510 has a wide range of applications. It can be used in hydraulic arresters, buffers, hydraulic drive valves and instruments in nuclear power plants, as well as other applications with radiation exposure. Additionally, it serves as a high - temperature heat carrier in insulation, lubrication, damping, shock absorption, and dust - proof applications, and can also be used as the base oil for high - temperature lubricating oils and greases.
IOTA BJ510 is packaged in 25 kg or 200 kg drums, which is convenient for transportation and storage. When stored in its original unopened container at or below 60℃, it has a shelf life of 60 months from the date of production, providing users with a relatively long usage period and reducing the hassle of frequent product replacement.
