JG-2201 Polymethylphenyl siloxane fluid_Jiangxi Si Bo Chemical Co., Ltd.

1、performance

This product is colorless or light yellow transparent liquid. Like methylsilicone oil, it shows excellent electrical insulating performance, high resistance to ozone and corona as well as desirable hydrophobic performance. It is also low in viscosity-temperature coefficient and surface tension, resistant to cutting, and has large compression. Because phenyl has been introduced to molecular chain, this enables the product to surpass methylsilicone oil in terms of such performance as high temperature resistance, anti-radiation, lubrication and dissolution. Its operating temperature ranges from -50℃ to 250℃.

2、Main function

Applicable to insulation, lubrication, damping, anti-vibration, prevention against dampness and dust, high-temp. hydraulic oil, and high-temp. heat carrier;

250-30 is mainly applicable to the impregnating oil of power capacitor.

It shows wide operating temperature, high safety and reliability, excellent gassing and dielectric property. It can also be used as the medium for passing the pressure signal of various pressure transmitters.
