1. What is dimethyl silicone oil?
Dimethyl silicone oil, also known as polydimethylsiloxane, is a colorless, odorless, non-toxic, non-volatile liquid. It is prepared by hydrolysis of dimethyldichlorosilane with water to obtain the primary polycondensation ring body, the ring body is cracked and distilled to obtain the low ring body, and then the ring body, end-capping agent and catalyst are put together to obtain a mixture of various polymerization degrees. Methyl silicone oil can be obtained by removing low-boiling substances by vacuum distillation.
2. Characteristics of dimethyl silicone oil
Due to its unique chemical structure, dimethyl silicone oil exhibits the following series of excellent properties:
Excellent thermal stability: dimethyl silicone oil can remain stable at high temperatures and is not easy to decompose or produce harmful substances. This feature gives dimethyl silicone oil a significant advantage in high-temperature working environments, such as insulation and lubrication of motors, electrical appliances, electronic instruments and other equipment.
Good anti-combustion: Its high flash point and non-flammable properties make dimethyl silicone oil have significant advantages in environments that require fire protection or high temperatures.
Good electrical insulation: The high resistivity and low dielectric constant of dimethyl silicone oil make it an ideal choice for electrical insulation materials.
Low freezing point temperature: Even at extremely low temperatures, dimethyl silicone oil can maintain fluidity and stability.
Low surface tension: Dimethyl silicone oil can easily spread on the surface of objects to form a uniform lubricating film, which plays a good lubricating and isolating role, and is suitable as a lubricant and surface treatment agent.
High compression resistance: It can withstand greater pressure without being easily deformed. Its stability and reliability under high pressure environments are suitable for application scenarios that require high compression.
Good oxidation resistance: Even in long-term use, dimethyl silicone oil can maintain good performance and is not easily oxidized.
Weather resistance: Dimethyl silicone oil has good resistance to environmental factors such as ultraviolet rays and ozone, and can maintain stable performance for a long time.
Viscosity changes little with temperature: The viscosity of dimethyl silicone oil is less affected by temperature, allowing it to maintain stable performance under different temperature conditions.
IV. Application of dimethyl silicone oil
Due to its unique properties, dimethyl silicone oil is widely used in many fields.
Cosmetics and personal care products: Dimethyl silicone oil has good lubricity and skin compatibility, so it is often used as an additive for cosmetics and personal care products, such as skin care products, shampoo, shower gel, etc.
Electrical industry: The high electrical insulation properties of dimethyl silicone oil make it an important material in the electrical industry, used to make insulating oil, cable oil, transformer oil, etc.
Mechanical industry: Dimethyl silicone oil has good lubricity and high temperature resistance, and is suitable for lubrication and cooling of various mechanical equipment.
Rubber and plastic industry: Dimethyl silicone oil can be used as a processing aid for rubber and plastic to improve its processing performance and product quality.
Pharmaceutical industry: Dimethyl silicone oil is also used in the pharmaceutical industry, such as as a matrix for ointments, creams and other preparations, with good lubricity and skin permeability.
V. Product selection
The viscosity of dimethyl silicone oil ranges from 20,000 to 500,000 cst. Dimethyl silicone oils of different viscosities have different uses:
Low viscosity dimethyl silicone oil: Suitable for cosmetics, skin care products and personal care products because of its excellent lubricity and skin compatibility.
Medium viscosity dimethyl silicone oil: commonly used as lubricant, damping medium and electrical insulating oil, suitable for mechanical, electronic and electrical industries.
High viscosity dimethyl silicone oil: suitable for processing aids in rubber, plastic and coating industries, which can improve product performance and stability.
Weici Chemical brand products: Dow PMX-200 series, Wacker AK series, Spark DM series, Spark 47V series.
In summary, dimethyl silicone oil has become an indispensable and important substance in the chemical industry due to its unique physical and chemical properties, excellent characteristics and wide application fields. Whether in industrial production or daily life, dimethyl silicone oil plays an important role and brings convenience and comfort to people's lives.
