Phenyl silicone oil
What is phenyl silicone oil?
Phenyl silicone oil is the product of some methyl -based phenyls in methyl silicon oil, and the thermal expansion coefficient is small.
Folding rate: 1.470 ～ 1.485 Sports viscosity (CS): 25 ～ 2000
Colorless or pale yellow transparent oily substance. Flash point> 300 ° C. The solidification point containing 5mo1%benzene silicone oil is low -70 ° C, and the surface tension is about 2.1 × 10-4 ～ 2.85 × 10-4n/cm, the relative density is 1.00-1.11, and the refractive index is 1.425 ～ 1.533.
The thermal stability is good. The gelization time in the hot air at 250 ° C is 1750h. It also has good radiation resistance and high oxidation stability, heat resistance, combustion resistance, ultraviolet resistance and chemical resistance.
The hydrolyzed reactions of octopus cycle tetraoxane, and methar Phenoxysilane can be used under the presence of catalysts. Used as a carrier of lubricating oil, heat exchange solution, insulation oil, gas liquid chromatography, etc. For insulation, lubrication, damping, shockproof, dust proof, and high temperature heat carrier, it is an ideal liquid damping media for electronic instruments.
Product characteristics of phenyl silicone oil
Phenyl silicone oil has higher viscosity coefficients, lower solidification points, and flash points than di metharilic silicone oil with the same viscosity.
The low temperature resistance of low benzene oil is significant, and it is also liquid in -70 ° C. With the increase of phenyl Moore scores, the high temperature resistance, radiation resistance, lubrication, and solubility in organic solvents are improved; but low temperature resistance decreases.
The oxidation occurs only when phenyl more score is high above 250 ° C, and the viscosity is increased; especially for the 50%silicon oil of the phenyl Moore score, add a stabilizer for hundreds of hours at 300-350 ° C.

Phenyl silicone oil Mainly used
Due to excellent performance, phenyl silicone oil can be applied to many areas of national life and production.
- In the application field of methyl silicon oil, the use of methyl benzhenyl silicon oil can be used to use its specialties with low temperature resistance, high temperature resistance, lubrication, and phase -soluble. Low phenyl silicon oil is particularly suitable for high -precision occasions; medium benzene and high benzene silicon oil have high heat stability, and good radiation resistance. The high -temperature lubricating fat made of carbon black, lithium soap or molybdenum sulfide can be used for high -temperature fan bearings, pearl bearing, automotive engine, textile dryer, etc.
- In addition, it is also widely used in hydraulic, instrumentation, electrical insulation, etc. Phenyl ethylene silicone oil and phenyl hydrogen -containing silicone oil can be used to prepare high temperature -resistant and spoke -resistant plus composite silicon rubber. The hydroxyl -sealing phenyl silicone oil as a fabric can significantly improve the smoothness and softness of the fabric, and give the fabric good hydrophobic refusal. The internal additives of plastic with good phase solubility with phenyl silicon oil can improve their processing performance.
- The phase -soluble of methamphetamine and cosmetics components is better than methyl silicon oil. It is stable in heat and ultraviolet rays, and has a unique gloss. It is often used as additives such as skin care products and conditioner [. Silicon oil containing methyl benzene -based silicon oxygen chains can prepare colorless transparent products with moderate viscosity and moderate viscosity, and use its high light transparency, high refractive index, good thermal stability, radiation resistance and other characteristics.
