Choosing Silicone Oil for High-Temperature Applications

In applications such as vacuum coating, high-temperature heat transfer, and electronic encapsulation, equipment and processes often need to operate continuously at temperatures ranging from 250°C to 300°C, or even higher. Under such extreme conditions, conventional methyl silicone oils are prone to molecular chain scission, leading to oil decomposition, volatilization, or coking, which makes them unsuitable for long-term, stable operation. Therefore, selecting a silicone oil with excellent thermal stability is crucial for ensuring the smooth execution of high-temperature processes.

IOTA 255: Engineered for High-Temperature Environments

IOTA 255 is a phenyl silicone oil. Its molecular structure incorporates phenyl groups, which give it superior performance at high temperatures compared to conventional silicone oils.

• Excellent Thermal Stability: The introduction of phenyl groups enhances the rigidity of the molecular chain, enabling it to withstand higher operating temperatures. IOTA 255 can operate stably for extended periods within the 250°C to 300°C range without undergoing thermal decomposition.
• Low Volatility: At high temperatures, IOTA 255 exhibits minimal volatilization loss, helping to maintain system vacuum levels and reducing contamination caused by oil evaporation.
• Excellent Lubricity: Even under high-temperature conditions, IOTA 255 maintains good lubricating properties, making it suitable for lubrication scenarios such as high-temperature bearings and high-temperature chains.
• Reliable Physical Properties: It appears as a colorless, transparent liquid with good fluidity and spreading characteristics.

Wide Range of Applications

Thanks to its temperature resistance, IOTA 255 is widely used across multiple industries and equipment that operate in high-temperature environments.

• High-Temperature Lubrication: Used for lubricating high-temperature bearings, chains, valves, and other components.
• High-Temperature Heat Transfer Medium: Serves as a high-temperature heat transfer oil or medium in heating systems requiring precise temperature control.
• Vacuum Coating: Functions as a diffusion pump oil or vacuum system sealing oil, maintaining a high-vacuum environment during the coating process.
• Electronic Encapsulation: Used for potting and insulating electronic components that require high-temperature resistance.
• Plastic Mold Release: Acts as a release agent for high-temperature molds, suitable for injection molding of engineering plastics.
