Product Description

Silicone oil is generally colorless or light yellow, tasteless, non-toxic, non-volatile liquid. Silicone oil insoluble in water.In cosmetics and many components have a high degree of compatibility, reduce the sticky feeling of the product, as a co-solvent, solid powder dispersant, used for refreshing cream, lotion, facial cleanser, makeup, perfume. Silicone oil has excellent heat resistance, oxidation resistance and low temperature resistance. It can be used for a long time in the temperature range of -50℃±180℃. Strong shear resistance, more than 20 times the compressibility of general mineral oil, is the ideal liquid spring; Low temperature viscosity coefficient, low steam pressure, low surface tension, good water increase and lubricity; Excellent electrical characteristics, high breakdown voltage resistance, arc resistance, corona resistance, low dielectric loss; It also has the advantages of good light transmittance and non-toxic effect on human body. A silicone oil is any liquid polymerized siloxane with organic side chains. The most important member is polydimethylsiloxane. These polymers are of commercial interest because of their relatively high thermal stability and their lubricating properties.

Key Applications

Silicone oils are primarily used as lubricants, thermic fluid oils or hydraulic fluids. They are excellent electrical insulators and, unlike their carbon analogues, are non-flammable. Their temperature stability and good heat-transfer characteristics make them widely used in laboratories for heating baths ("oil baths") placed on top of hotplate stirrers, as well as in freeze-dryers as refrigerants. Silicone oil is also commonly used as the working fluid in dashpots, wet-type transformers, diffusion pumps and in oil-filled heaters. Aerospace use includes the external coolant loop and radiators of the International Space Station Zvezda module, which rejects heat in the vacuum of space.

The class of silicone oils known as cyclosiloxanes has many of the same properties as other non-cyclic siloxane liquids but also has a relatively high volatility, making it useful in a number of cosmetic products such as antiperspirant.

Some silicone oils, such as simethicone, are potent anti-foaming agents due to their low surface tension. They are used in industrial applications such as distillation or fermentation, where excessive amounts of foam can be problematic. They are sometimes added to cooking oils to prevent excessive foaming during deep frying. Silicone oils used as lubricants can be inadvertent defoamers (contaminants) in processes where foam is desired, such as in the manufacture of polyurethane foam.

Silicone oil is also one of the two main ingredients in Silly Putty, along with boric acid.

Other Applications

Medical uses: Consumer products to control flatulence often contain silicone oil. Silicone oils have been used as a vitreous fluid substitute to treat difficult cases of retinal detachment, such as those complicated with proliferative vitreoretinopathy, large retinal tears, and penetrating ocular trauma. Additionally, silicone oil is used in general medicine and surgery. Because of silicone oil's water repellent and lubricating properties, it is considered an appropriate material to maintain surgical instruments. They are also used in digital rectal examinations (DRE).

Automotive use: Silicone oil has been commonly used as the fluid in the automobile cooling fan clutch assemblies, and is still being used in the newer electronic fan clutches.0.

FAQ

How to distinguish the pure silicone oil and ungraded silicone oil?

(1)  Check by your observation: pure silicone oil is a transparent liquid without any smell, but ungraded silicone oil smells bad and in a turbid liquid form.

(2)  To test it by fire. take the pontil or glass rod to dip some liquid , if it can be lighted and fumed when burning, so the liquid is the ungraded silicone oil ,which is a kind of petrochemicals. And, Pure silicone oil can not be fired, which is colorless, odorless, clear, nontoxic. The burning point of pure silicone oil is 320C,but ungraded silicone oil is 100C.

(3)  Freezing point Method: Take 100g of two kinds of silicone oil into refrigerator at the same time. Under temperature of-5 to -10 C for 2 hours, ungraded silicone oil will turn to turbid or frozen ,while pure silicone oil is still clear and transparent as before, and it will not freeze until -5 0 0C.

Polydimethylsiloxane, a colorless and transparent liquid or elastomer, has excellent thermal and chemical stability. It is a silicon-based polymer widely used in lubricants, sealants, medical equipment, and cosmetics. PDMS is known for its low surface tension, biocompatibility, and nonreactivity, and can be synthesized through various methods, including hydrolysis polymerization. Polydimethylsiloxane is an important material in organic silicon chemistry due to its multifunctionality and wide range of applications.
