Performance characteristics
This product is a colorless and transparent new synthetic polymer materials, there are a variety of different viscosity (5cps ~ 8 million cps), from easy flow of liquid to thick semi-solid. This product has special smoothness, softness, hydrophobicity, good chemical stability, excellent electrical insulation and high and low temperature resistance. High flash point, low freezing point, can be used for a long time at -50 ℃ ~ 200 ℃, low viscosity-temperature coefficient, high compression rate, low surface tension, good water repellency and moisture resistance, and small specific thermal conductivity.

Use
Due to the low surface tension of silicone oil and poor solubility with other substances, that is, the special interface of silicone oil, giving it excellent defoaming properties, it can be used in different industries: such as the petroleum industry (crude oil extraction and transportation, refining, oil and gas and aromatics Separation, distillation, etc.), rubber industry, coating industry, textile industry, paper industry and food processing industry.
Usage and dosage
Depending on the specific application object and application environment, the dosage varies from a few PPM up to 100%.
Precautions
Contact with high concentration of strong acid or alkali substances and Lewis acid has the tendency of degradation and volatilization, the higher the temperature, the more obvious the reaction. There is a tendency for the viscosity to become high up to cross-linking when a strong acid or a strong base is brought into contact with it at a low concentration or under the action of a high temperature for a long time.
