In the vast world of industrial fluids, IOTA BJ1000 phenyl silicone oil stands out with its unique properties, making it a popular choice in various fields. It is a transparent, colorless, and odorless polydimethylsiloxane containing a significant amount of phenyl groups. This special chemical structure endows it with a series of excellent characteristics.
IOTA BJ1000 has a broad spectrum of applications. In the heat - transfer field, it serves as an efficient heat - transfer fluid, ensuring that equipment operates at a stable and appropriate temperature. For pressure transmission, it can accurately convey pressure signals, meeting the requirements of precision equipment. In the electronics industry, it acts as an ideal dielectric in capacitors and transformers, providing a stable electrical environment for electronic components. Additionally, it functions as a base fluid for heat - resistant lubricants, offering reliable lubrication protection to mechanical parts under high - temperature conditions.
The effective temperature range of this silicone oil is from - 35°C to + 200°C, but this is based on the condition that the fluid's thermal stress occurs under "pure chemical" circumstances. In practical use, even trace amounts of acids, bases, mineral oils, organometallic compounds, metal salts, or metal oxides can significantly reduce its service life. Moreover, the flash point of silicone fluids may change due to thermal stress. Therefore, in open systems, it is crucial to check the flash point at least once a year, and more frequently if the operating conditions require.
Visually, IOTA BJ1000 is transparent and colorless, giving an impression of purity. At 25°C, its viscosity ranges from 900 - 1300 mPa.s (tested by DIN 51562), the refractive index is approximately 1.51 (DIN 51423), and the density is about 1.09 g/cm³ (DIN 51757). Its volatility is less than 1.0% under the condition of 5g/2h/250°C. The thermal conductivity at 50°C is about 0.14 Wm⁻¹K⁻¹, and the specific heat at 25°C is approximately 1.46 Jg⁻¹K⁻¹. The coefficient of thermal expansion in the range of 0 - 180°C is 85 - 82 x 10⁻⁵ mLmL⁻¹K⁻¹. The dielectric constant at 25°C and 100 Hz is about 2.9, the dielectric strength is about 20 kVmm⁻¹, the flash point is approximately 280°C (ISO 2719), and the ignition temperature is greater than 400°C (DIN 51794).
