Both ethyl silicone oil and silicone oil have their applicability in demolding applications, but which one is more suitable for demolding depends on the actual application scenario and requirements. Here is a detailed comparison between the two:


Ethyl silicone oil
characteristic:

The working temperature range is -60~150 ℃, and the temperature viscosity coefficient is small, with excellent lubrication and dielectric properties.
The freezing point is below -70 ℃, the relative density is 0.95-1.05, and the flash point is above 265 ℃ (open cup).
Colorless to light yellow transparent liquid, soluble in organic solvents such as toluene, ether, chloroform, etc., can be mixed with petroleum products at will.
It has the characteristics of low volatility, low surface tension, non toxicity, non corrosiveness, and aging resistance.

Application:
Mainly used as a release agent for various rubber and plastic products, it can effectively prevent products from adhering to molds.
It can also be used as insulation material in the electrical industry, precision instrument oil, hydraulic oil, special lubricating oil, etc.
silicone oil

Classification and Characteristics:
Methyl silicone oil: Good lubricity and antioxidant properties, but not suitable for high temperature environments.
Vinyl silicone oil: More resistant to high temperatures, commonly used in the manufacture of high-temperature lubricants and other materials.
Polysiloxane: It can be used at extremely high temperatures and is the preferred material for high-temperature lubrication and protection.

Application:
Silicone oil is widely used as a release agent in industries such as rubber, plastic, metal casting, glass, paper, and fiber production.
In the chemical industry, silicone oil is used as defoamer, which can effectively eliminate foam and prevent foam regeneration.
In the field of biotechnology, silicone oil is used to separate biomolecules such as DNA and proteins, and as a lubricant and anti adhesive in cell culture and bioreactors.

Comparison and Selection
Temperature adaptability: Ethyl silicone oil has a wide working temperature range (-60~150 ℃) and is suitable for demolding most rubber and plastic products. The adaptability of different types of silicone oil (such as methyl silicone oil, vinyl silicone oil, etc.) to temperature varies, and the selection should be based on the specific usage temperature.
Lubrication performance: Ethyl silicone oil has excellent lubrication performance, which can effectively reduce the friction between the mold and the product, making the demolding process smoother. Silicone oil also has lubricating properties, but the lubricating properties of different types of silicone oil vary.
Chemical stability: Both ethyl silicone oil and silicone oil have good chemical stability and can maintain their performance stability under various environmental conditions.
Cost: Generally speaking, the cost of ethyl silicone oil may be higher than certain types of silicone oil (such as methyl silicone oil), but lower than other high-performance silicone oils (such as vinyl silicone oil or polysiloxane). Therefore, cost factors need to be considered when making a choice.
In summary, both ethyl silicone oil and silicone oil have their advantages in demolding applications. Ethyl silicone oil is particularly suitable for demolding rubber and plastic products due to its excellent working temperature range, lubrication performance, and chemical stability. Silicone oil, on the other hand, has a wide range of applications in different industries and fields due to its diverse types and broad applicability. The specific choice of silicone oil as a release agent needs to be determined based on the actual application scenario and requirements.
