Applications of Phenyl Methyl Silicone Oil LC-P258

  • High temperature electrical insulation and impregnation: used as impregnating insulation oil for high-voltage capacitors, transformers, and transformers.

  • Precision instrument damping and shock absorption: As a damping fluid for aviation instruments, pointer precision instruments, and hydraulic dampers, it has stable viscosity and temperature characteristics with a viscosity of 125, and a constant damping force in high and low temperature environments. It is used for instrument pointer buffering, vibration absorption, and inertia damping control.

  • Medium to high temperature heat transfer medium: suitable for closed or open high-temperature heat transfer systems, laboratory hot baths, and semiconductor wafer heat treatment heat transfer oils; Moderate viscosity, easy to circulate and flow, high temperature resistance without coking.

  • Aerospace and radiation resistant components: used for lubrication and damping of precision mechanisms in spacecraft and satellites, as well as insulation and sealing fluids for nuclear power equipment; Resistant to cosmic radiation and alternating high and low temperature environments, ensuring the safety of aircraft engine accessories.

  • High temperature lubrication and bearing protection: lubricating oil for high-temperature bearings, gears, and chains, suitable for high-temperature equipment such as textile printing and dyeing, glass manufacturing, etc; Not corrosive to metals, not adhering to dust.

  • Optical electronics and coating additives: used as refractive index matching fluid for optical instruments, auxiliary additives for LED packaging, and moisture-proof and hydrophobic coatings for electronic components.

  • Silicone rubber modification and industrial auxiliary: As a high-temperature additive of silicone rubber, it can improve the temperature resistance grade and aging resistance of rubber products.
