Basic Characteristics
Phenyl silicone oil IOTA BJ1000 is a transparent, colorless, and odorless polydimethylsiloxane containing a significant amount of phenyl groups. This unique chemical structure endows it with a series of excellent physical and chemical properties. In terms of appearance, it presents a clear and transparent state, giving a sense of purity and high quality. Its viscosity at 25°C ranges from 900 - 1300 mPa.s, and this moderate and stable viscosity enables it to exhibit good fluidity and adaptability in various application scenarios.

Wide Range of Applications
IOTA BJ1000 finds important applications in multiple fields. As a heat - transfer fluid, it can efficiently transfer heat and plays a crucial role in systems that require precise temperature control. In the field of pressure - transfer fluids, it can accurately transmit pressure signals to ensure the stable operation of the system. In capacitors and transformers, it serves as a dielectric, effectively isolating charges and safeguarding the normal operation of electrical equipment. Additionally, it is an excellent choice as a base fluid for heat - resistant lubricants, providing reliable lubrication protection for mechanical equipment under high - temperature conditions.

Reliable Performance Parameters
The product's various performance parameters have undergone rigorous testing. Its refractive index at 25°C is approximately 1.51, and its density is about 1.09 g/cm³. These parameters are of great importance for application scenarios that have requirements for optics and density. In terms of thermal properties, its thermal conductivity at 50°C is about 0.14 Wm⁻¹K⁻¹, its specific heat at 25°C is about 1.46 Jg⁻¹K⁻¹, and its coefficient of thermal expansion in the range of 0 - 180°C is 85 - 82 x 10⁻⁵ mLmL⁻¹K⁻¹. These data indicate that it has good characteristics in heat transfer and thermal expansion. In terms of electrical properties, its dielectric constant at 25°C and 100 Hz is about 2.9, and its dielectric strength is about 20 kVmm⁻¹, meeting the requirements of electrical equipment for insulation performance.

Usage and Storage Precautions
In practical applications, the effective temperature range of IOTA BJ1000 is from - 35°C to + 200°C, but this is under the condition of "pure chemistry". Even trace amounts of acids, bases, mineral oils, organometallic compounds, metal salts, or metal oxides can significantly reduce its service life. In open systems, it is particularly important to check the flash point at least once a year, and more frequently if required by operating conditions. For storage, the "use - by date" of each batch of products is shown on the label. Storage beyond the specified date does not necessarily mean that the product is no longer usable. However, in this case, for the sake of quality assurance, it is necessary to check the properties required for the intended use.
