The domestic substitution of IOTA 255 phenolic silicone oil has been accelerated. It answers the core questions regarding selection and application.

1. The advantages of phenolic materials are prominent. IOTA 255 is suitable for optical and radiation-resistant scenarios.
Ordinary dimethyl silicone oil has limited heat resistance and radiation resistance. However, IOTA 255 phenolic silicone oil introduces phenolic groups into its molecular chain, enhancing its refractive index and radiation resistance. Its refractive index ranges from 1.4600 to 1.5150, with good light transmission and is not prone to yellowing at high temperatures. Besides traditional industrial lubrication, it can also be used for filling optical components and as a medium for radiation-resistant equipment, suitable for emerging fields such as new energy and precision instruments, enabling the domestic application of high-end phenolic silicone oil.

2. Common customer questions: Will IOTA 255 phenolic silicone oil solidify in low-temperature environments?
Question: For outdoor low-temperature equipment in the north, will IOTA 255 phenolic silicone oil freeze and fail in winter?
Answer: The conventional model has a freezing point of ≤ -70℃. It still maintains good fluidity in low-temperature environments and will not solidify. Some specialized models can extend to -120℃ ultra-low temperature conditions, suitable for outdoor instrument damping and low-temperature start-up lubrication scenarios in cold regions.

3. Common customer questions: Can IOTA 255 phenolic silicone oil directly replace imported phenolic silicone oil?
Question: If the original equipment uses imported phenolic silicone oil, is it feasible to directly replace it with IOTA 255?
Answer: The core technical indicators of IOTA 255 are benchmarked against similar imported phenolic silicone oil, possessing the potential for domestic substitution. It is not recommended to directly replace the entire machine. Small sample tests need to be conducted first to verify compatibility, volatility rate, and long-term aging performance, and confirm the matching working conditions before batch purchasing to avoid application risks.


4. The electrical insulation performance is reliable, meeting the requirements of high-voltage precision equipment.
IOTA 255 phenolic silicone oil has excellent electrical insulation performance, with low dielectric loss and high breakdown strength. It can be used as an insulation emulsion for electrical equipment and maintains insulation stability in alternating high-temperature environments. At the same time, it has excellent hydrophobic properties, and is not prone to absorbing water in humid environments, reducing the risk of electrical equipment leakage. It is a reliable special organic silicon raw material for the power and precision electronics industries.
