Excellent thermal stability up to 250 °C, maintaining viscosity integrity under prolonged high-temperature exposure.
Superior oxidative resistance compared to standard methyl silicone oils, minimizing degradation in demanding environments.
Low volatility and high flash point (≥300 °C), enhancing process safety and reducing evaporation loss during handling.
Good compatibility with organic polymers, resins, and fillers—ideal for formulating high-performance composites and coatings.
Hydrophobic yet non-yellowing, providing long-term clarity and surface protection in optical and electronic applications.
High-temperature heat transfer fluids in industrial circulation systems and thermal management units.
Base fluid in specialty lubricants for precision instruments, vacuum pumps, and aerospace mechanisms.
Viscosity modifier and release agent in silicone rubber and RTV/HTV compound processing.
Dielectric fluid in high-voltage transformers and capacitors requiring stable insulation performance.
Carrier medium for functional additives in LED encapsulants and optical adhesives.
