7 major applications! High viscosity dimethyl silicone oil Look here!
A linear dimethyl silicone oil with Si O-Si as the main chain and methyl groups connected to silicon atoms. Due to the small intermolecular force, the molecules have a helical structure, with methyl groups arranged outward and freely rotating. The structural formula is as follows:
Therefore, it has a series of characteristics, such as colorless transparency, wide viscosity range (can range from 0.65 to 1000000mm2/s), low temperature viscosity coefficient, high expansion coefficient, low vapor pressure, high flash point, high and low temperature resistance, weather resistance, radiation resistance, low surface tension, high compression rate, anti oxygen plasma, high insulation, shear resistance, film forming ability, hydrophobicity, defoaming, demolding, high gloss, inert to materials, chemical inertness, non corrosion, and physiological inertness, It is precisely these characteristics that determine its broad application.
Generally, dimethyl silicone oil can be divided into three types of specifications based on its viscosity range:
Low viscosity silicone oil 0.65-50mm2/s;
Medium viscosity silicone oil 50-1000mm2/s;
High viscosity silicone oil from 1000 to 1000000mm2/s.
Zhonghaojing Enterprise Skycore ® The series of high viscosity dimethyl silicone oil is synthesized with high-quality new materials, with stable quality and compliance with EU RoHS standards. Conventional high viscosity options include 12500 viscosity, 60000 viscosity, 300000 viscosity, and 500000 viscosity. Other high viscosity options can be customized.
Main applications of the product
Daily chemical industry
It can be used in cosmetics formulas such as skincare creams, bath lotions, and shampoos, with excellent softness and a silky feel, and has functions such as moisturizing and protecting the skin
Mechanical and Electrical Industry
It can be widely used as an insulation medium for temperature resistance, arc corona resistance, corrosion resistance, moisture resistance, and dust prevention in motors, electrical appliances, and electronic instruments. Currently, it is also used as an impregnant for transformers, capacitors, and scanning transformers in televisions. Used as a liquid shockproof and damping material in various precision machinery, instruments, and instruments. The shock-absorbing performance of 201 methyl silicone oil is less affected by temperature, and it is mostly used in instruments such as those in aircraft and automobiles that have strong mechanical vibrations and large environmental temperature changes.
Used as a defoamer
Due to its low surface tension and insoluble in water, dimethyl silicone oil has good chemical stability and is non-toxic in animal and vegetable oils, as well as high boiling mineral oils. It has been widely used as a defoamer in industries such as petroleum, chemical, medical, pharmaceutical, food processing, textile, printing and dyeing, papermaking, etc. Only 10-100PPM of silicone oil needs to be added to have a good defoamer effect.
As a release agent
It is not sticky to rubber, plastic, metal, etc., and is also used as a release agent for various rubber and plastic products forming and processing, as well as in precision casting. Using it as a demolding agent not only facilitates demolding, but also makes the surface of the product clean, smooth, and with clear texture.
Apply insulation, dust and mold resistant coatings
Dip a layer of 201 methyl silicone oil on the surface of glass and ceramics, and heat treat at 250-300 ℃ to form a semi permanent waterproof, mold proof, and insulating film. Using it to treat insulating devices can improve their insulation performance: using it to treat optical instruments can prevent mold from forming on lenses and prisms; Using it to handle drug bottles can extend the shelf life of the drug without causing any loss of the preparation due to sticking to the wall; Use it to treat the surface of movie film,
