In the field of refrigerants, the branched siloxane oligomer methyl tris(trimethylsiloxy)silane has been widely studied and applied due to its excellent physicochemical properties.
Refrigerant characteristics

1. Chemical stability: The branched siloxane oligomer methyl tris(trimethylsiloxy)silane is non-corrosive and friendly to equipment and the environment.
2. Non-toxicity: It is non-toxic to humans and the environment and meets safety use standards.
3. High boiling point: The boiling point exceeds 191 °C, ensuring stability even at high temperatures.
4. Temperature range: Suitable for low-temperature environments from -70 °C to -30 °C.

Wear inhibitor tris(p-tolyl) phosphite: As a wear inhibitor, it effectively reduces friction and wear of the refrigerant in the circulation system.
Viscosity of refrigerant
Viscosity at working temperature: At -40 °C, the viscosity is 5.7 mm²/s, ensuring good fluidity of the refrigerant at low temperatures.
Application examples

1. Formula ratio: Adding 0.5 parts of tris(p-tolyl) phosphite to 100 parts of methyl tris(trimethylsiloxy)silane forms a high-performance refrigeration oil.
2. Performance test: Under the condition of -40 °C, with a circulation rate of 8 L/min and running for 12 hours a day for 31 consecutive days, the function of the refrigerant is still normal, showing its excellent durability and stability.

Other applications

1. Automotive coolant: Suitable for cars in cold regions and provides antifreeze protection in low-temperature environments.
2. Transformer oil: When used as transformer oil, it has excellent insulation and cooling properties.
3. Refrigeration oil: Used as a lubricating and cooling medium in refrigeration equipment to improve equipment efficiency and lifespan.
