Low temperature resistant silicone oil
is a special type of silicone oil that has excellent low-temperature resistance and can maintain its performance in extreme low-temperature environments. The following is a detailed introduction to low-temperature resistant silicone oil:


1、 Product Overview
Low temperature resistant silicone oil is a modified phenyl silicone oil with high phenyl content. Compared with ordinary phenyl silicone oil, it has better low temperature resistance and a wider working temperature range, generally between -120 ℃~280 ℃ (also known as -110 ℃~250 ℃ or -80 ℃~200 ℃, depending on the product type and manufacturer). This silicone oil can maintain high fluidity at low temperatures and is not easily solidified, so it is widely used in various applications that require low-temperature resistance.

2、 Technical indicators
The technical indicators of low-temperature resistant silicone oil vary depending on the manufacturer and product type, but usually include the following aspects:

Appearance: Colorless or pale yellow transparent liquid.
Viscosity: The viscosity range varies depending on the specific product and application requirements.
Relative density: generally between 1.00 and 1.02.
Flash point: The open cup flash point is generally higher, greater than or equal to 280 ℃ (there are also products with lower flash points, such as 175 ℃).
Condensation point: The condensation point is relatively low, generally less than or equal to -120 ℃ (there are also products with slightly higher condensation points, such as -80 ℃).
Refractive index: At a specific temperature, the refractive index has a certain range
