Dimethyl silicone oil, also known as polydimethylsiloxane, is a hydrophobic silicone material. It is used in various fields such as medicines, daily chemicals, food, and construction.
In terms of production process, dimethyl silicone oil has the functions of "cracking method" and "hydrolysis method".
What is the lysis method?


Where do plastic materials come when producing plastic products? On the one hand, it is possible to buy plastic particles from petrochemical-related companies, and on the other hand, buy recycled plastics from small workshops. Similarly, the two methods of dimethicone basically represent different sources of the product.
The cleavage method, that is, re-decomposing into waste monomer by using waste silica gel to prepare a silicone oil. The method has low process cost and difficulty. According to different types of silica gel, different impurities may be brought in, which is what we call "secondary furnace".






The hydrolysis method, that is, starting from SiO2-Si-chlorosilane-silicone oil, does not introduce impurities during the production process. The produced silicone oil is colorless and odorless, and the process can be adjusted as needed to obtain a silicone oil having a relatively narrow viscosity distribution.








So, if you buy Gutian Chemical's dimethicone, you don't have to worry about the source of the product. It must be the source of the “hydrolysis method” and it comes from the international big name “Dow Corning”. Below, we will introduce the three types of products of Dow Corning Dimethicone, which is represented by Gutian.








1, food grade silicone oil




Hydrolysis production;
Suitable for applications related to food packaging, equipment, etc.;
Customs-level food-grade commodity inspection and declaration, giving customers the greatest support for food-related products.




Disposable paper cup mouth lubrication - food grade silicone oil


2, pharmaceutical grade silicone oil


Hydrolysis production;
Dow Corning issued a FDA-compliant statement and a domestic third-party certification report;
Applicable to all kinds of medical equipment external preparations, lubrication products in contact with human skin.


Condom lubricants must use safe, healthy, and guaranteed pharmaceutical grade silicone oils.




3. Industrial grade silicone oil


Divided into ultra low viscosity, low viscosity, medium viscosity, high viscosity, ultra high viscosity silicone oil;
Viscosity varies from 0.65cs to 1,000,000 cs;
The entire line of products is used in the daily chemical series;
In addition, it can also be applied to textiles, lubricating greases, defoamers, silicone rubber and other industries.
