Organosilicon, it is also called organosilicon compound. Organosilicone compound is what is composed by Si-C bonds and at least one organic group is directly connected to the silicon atom.Usually, those organic groups like oxygen, nitrogen, sulfur, etc, connecting to the silicon atom are also called silicone compound. Among all of them, polysiloxanes composed by silicon-oxygen bonds (-Si-O-Si-) are the most popular types. They are the most widely applied and researched type among all organosilicon compounds, which accounts for more than 90%. As per different forms, silicone materials can be grouped into: biologically active silicone, silane coupling agent (organosilicon chemical reagent), silicone oil (silicone emulsion, silicone surfactant, silicone grease), liquid silicone rubber,high-temperature vulcanized silicone rubber, silicone resin, etc. Silicone compounds have both properties of organic materials and inorganic materials. They have excellent performance such as:low and high temperature resistance, radiation resistance,oxidation resistance, flame resistance, good dielectric properties, hydrophobic, mold release,and low temperature viscosity coefficient. Silicone compounds are also tasteless, non-toxic, tasteless and physiological inertia. With these properties, silicone products are widely applied in different industries, such as:construction, electrical and electronic, chemical, light industry, medical, personal care, textile, agrochemical industry and other industries. Along with the continuous increase of organic silicon products varieties, the application fields are also expanding. Silicone compounds has formed an important and unique product line in the field of new chemical materials. Many silicone varieties are irreplaceable and indispensable by other chemicals. With its wide application and development prospects in the forefront of science and technology, it is also known as technological catalysts and industrial vitamins. There are different types of organic silicone products. Its varieties and brands are over 10,000, and around 4,000 of them are commonly used. In 2018, the polysiloxane consumption in China was about 1.044 million tons. Silicone rubber accounted for 66.90% of the total consumption, silicone oil accounted for 29.50%, and silicone resin and others accounted for 3.60%. From the downstream part, the largest consumption is in industries like construction, electricity and new energy, electronic appliances, personal care and. It is expected that in the next 5 years, the main application of silicone materials will still among industries like construction, textiles, electronics, textiles, medical treatment and personal care;Photovoltaic, 3D printing, smart werable device and other new market will be the breakthrough point and market increase point for silicone materials.

Basic knowledge of Silicone Oil

Silicone oil is a liquid siloxane polymer with organic side chains. It has different properties: low surface tension, low thermal conductivity, high heat resistance, and high dielectric strength. Following are some key basic datas of silicone oil:

Chemical Properties: silicone oil is clear and colorless. It is also inert, non-toxic, and non-flammable. They can maintain viscosity at different temperature ranges and has a wide thermal stability. Comparing with petroleum-based oils, silicone oil does not degrade under high temperatures or in the presence of other chemicals.

Physical Properties: Silicone oil has low surface tension and can cover large surface areas. They are hydrophobic, repelling water,but can retain air and moisture within its structure. Silicone oils are also well known for its thermal stability, maintaining their properties under a wide temperature scope.

Viscosity: The viscosity of silicone oil plays an important role in its applications. It is from very thin fluid to thick condition, and from 1cst to over 10,000,000cst. This variability allows for different applications, from light lubrication to heavy damping requirements.

Compatibility: Silicone oils are generally non-reactive and compatible with most materials, but in certain plastics or rubbers, it may cause some problems. Consequently, conducting compatibility tests before using silicone oil with other substances is important.

Environmental Impact: Regarded as environmentally safe, silicone oil is non toxic and does not pose a threat to air or water quality under normal condition. However, they are not biodegradable, needs proper disposal to prevent environmental harm.

Applications: due to its unique properties, silicone oil can be used in various applications. They are commonly applied in lubricants, hydraulic fluids, heat transfer fluids, and dielectric fluids. Moreover, they are added in cosmetics, medical devices, and as antifoaming agents in food and industrial processes.


Applications of Silicone Oil

Silicone oil is a versatile liquid polymer, which has unique chemical and physical properties. This makes it a valuable element across various industries. Let’s check some of its primary applications.

Lubrication: Silicone oil can be used in lubricant in a wide range of conditions, particularly extreme temperatures. Its superior performance is suitable for automotive components like brake systems, spark plug boots, and o-rings.

Electrical Insulation: Silicone oil has high dielectric strength and non-conductivity. This makes it an good insulator for electrical components. Widely used in transformer oil with its cooling and insulating properties, silicone oil can prevent electrical discharges and strengthen the life span of high-voltage equipment.

Cosmetics and Personal Care: The silky feel of silicone oil makes it a popular choice in cosmetics and personal care products. It is used in skin care products for moisture barrier protection. It is used in hair care for the purpose of frizz control and shine.

Defoaming and Antifoaming Agents: Silicone oil’ has low surface tension. This makes it effective in breaking down foam in industrial processes like paper production and food processing. It helps control foam in different applications to bring efficient and safe operations.

Heat Transfer Fluids: With its high thermal stability, silicone oil serves as a reliable heat transfer fluid in different applications, including solar energy systems and industrial heating processes. It can transfer heat but doesn’t degrade at high temperatures. This can bring consistent performance.

Mold Release Agents: Silicone oil acts as a release agent in manufacturing processes. It can make products to be removed easily from molds.Both product quality and manufacturing time can be improved. Industries like rubber, plastics, and composites can benefit from this.

Textile Finishing: Silicone oil is applied to textiles to, which can increase softness, water repellency, and resistance to wrinkles. Its use in textile finishing processes can make the feel and durability of clothing better.

Damping Fluids: In automotive and mechanical engineering, silicone oil is used in shock absorbers and dampers, which can dampen vibrations and provide a smoother ride. It has good ability to maintain viscosity under different conditions. Thus it is a preferred choice for damping applications.

Medical Applications: Silicone oil’s biocompatibility and stability make it suitable for various medical applications. It is applied in lubricating medical instruments, syringes, and catheters.

The Common Points When Purchasing

Please note that the final cost is related with the customized service you require, the technical data of the raw materials used, the volume you need, the package required and the distance of transportation. For the international purchasing, there are some common points need to be noticed.

Limited Research: Not enough research on the market, product, and supplier can result in not suitable purchase decisions. Buyers should evaluate various suppliers as per their demands, and compare prices and qualities before sending Purchase Order.

Quality’s importance: choosing cheapest quotation without considering quality can result in higher long-term costs. Quality should be weighed against price.

Total Cost: Buyers should compare not only on the purchase price but also on other expenses like maintenance, operation, and disposal. Total cost is more precise estimation of the product’s cost.

Planning strategy: Purchasing without a good plan or strategy can lead to buy at not right time, which is more costly and less effective. A strategic purchasing approach ensures on time shipment and less stock

Supplier partnerships: putting suppliers as only vendors rather than partners may lead to less service, products, and pricing. Mutual beneficial relationships with suppliers can result in win win relationship.
