Product introduction of methyl silicone oil:
Methyl silicone oil is the largest and most widely used variety of silicone oil. Colorless, transparent, non-volatile; insoluble in water, methanol, ethylene glycol, miscible with benzene, dimethyl ether, methyl ethyl ketone, carbon tetrachloride or kerosene, has a small vapor pressure, high flash point and ignite. Methyl silicone oil has excellent heat resistance, electrical insulation, weather resistance, hydrophobicity, physiological inertness and small surface tension, as well as low viscosity-temperature coefficient and high compression resistance.

The main purpose:
Used as insulation, lubrication, shockproof, dustproof oil, dielectric fluid and heat carrier. It can also be used as an additive for defoaming, film release, paint and daily cosmetics. The excellent performance of the product is widely used in electronic appliances, building materials, motor manufacturing, transportation, petrochemical, textile, printing and dyeing, thread making, various polyester and polyester cotton, polyester rayon fabrics to improve the smoothness and elasticity of post-finishing and Medical and health, aviation research and military technology and other fields.
It is used for the treatment of sewing thread, increasing lubrication, and can be used for continuous thread on high-speed sewing machines. It is used for soft finishing of fabrics, increasing the lubricity of fabrics, increasing the smoothness, fullness and elasticity of fabrics.

Properties and uses of water-soluble silicone oil:
This product is a silicone oil that contains a variety of active gene modifications and is completely soluble in water. Used for finishing of cotton, wool, silk, polyester and other fibers to make them soft, breathable, smooth and antistatic. It is used in cosmetics to improve its softness, smoothness and moisturizing effect. Used in the food industry to defoam, lubricate, release molds and improve gloss. In addition, it is widely used in many industries such as plastics, rubber, petrochemical and so on.

Diffusion pump silicone oil properties and uses:
Diffusion pump oil is polymethylphenylsiloxane colorless transparent oily liquid with high phenyl content. The product has extremely low saturated vapor pressure, high temperature resistance, low temperature resistance, oxidation resistance, radiation resistance, stable chemical performance, and high vacuum degree. It is the most ideal liquid medium material in high vacuum systems. It is mainly used as high-vacuum diffusion pump oil in electronics, metallurgy, and instrumentation industries, and can also be used as a high-temperature heat carrier and transfer fluid in instruments.

Dimethyl hydroxy silicone oil emulsion (cationic type) properties and uses:
The product is a homogeneous emulsion of polydimethylsiloxane whose ends are capped with hydroxyl groups. Hydroxyl-based active genes are very easy to polycondense at low temperature to form elastic films. Methyl-based hydrophobic gene. It is mixed with a certain amount of methyl hydrogen-containing silicone oil emulsion to have a good water-releasing effect. Widely used in finishing of synthetic fiber, silk, cotton and other fibers and fabrics. The finished fabric can achieve a good soft effect. Increase elasticity, increase wear resistance and washability, and also increase temperature resistance and water release performance.
