Silicone Oil Production Line Equipment
  • 1. Polymerization reactor

  • Used for the polymerization of dimethylsiloxane monomers. Equipped with heating, cooling, vacuum, stirring and condensation systems. Surfaces in contact with the material are typically madde of SS304/316.

  • 2. Condenser

  • Used to cool volatile substances generated during the reaction.

  • 3. Vacuum system

  • Ensures the reaction is carried out under low pressure, increasing the degree of polymerization and reducing by-products.

  • 4. Fractionator/Distillation equipment

  • Used to separate unreacted monomers and oligomers to achieve the target molecular weight distribution.

  • 5. Mixing reactor

  • Used for subsequent viscosity adjustment and the addition of functional additives (such as hydroxyl silicone oil, vinyl silicone oil, and hydrogenated silicone oil).

  • 6. Storage tank and filling machine

  • Stores finished products and allows for automated filling to ensure product purity and stability.

Silicone Oil Production Process
1. Raw material preparation: Dimethylsiloxane monomer and catalyst are added to the reactor.
2. Polymerization: Silicone oil is produced under controlled temperature and pressure.
3. Vacuum removal: Removes low-boiling substances and by-products.
4. Fractional distillation: Separates unreacted monomers and by-products to produce silicone oils of varying molecular weights.
5. Blending and modification: Hydroxyl silicone oil, vinyl silicone oil, mehtyl silicone oil, and other silicone oils are produced based on customer needs.
6. Storage and filling: The finished silicone oil is stored in tanks and then packaged.


Silicone oil is an important type of organosilicon material, widely used in lubrication, insulation, mold release, defoaming, textile auxiliaries, cosmetics, and medical fields. As market demand continues to expand, manufacturers have placed higher demands on efficient, stable and safe silicone oil production line equipments. With years of industry experience and accumulated technology, the silicone oil production line equipment developed and manufactured by JCT has the following significant technical advantages:

  • • Precise reaction control

  • The automated PLC control system enables real-time monitoring and adjustment of temperature, pressure and agitator speed. This ensures that the condensation and polymerization reactions proceed within the optimal process curve, improving the uniformity of the silicone oil's molecular weight distribution.

  • • Efficient heat transfer and energy-saving design

  • Reactor utilizes jacketed or external coil heating, coupled with a thermal oil circulation system, for efficient and stable heat transfer. This energy-saving heating system can reduce energy consumption by 15%-20%, lowering production costs.

  • • Professional mixing and dispersion system

  • The equipment is equipped with a multifunctional impeller (anchor, paddle or triaxial powerful dispersion structure) to ensure uniform mixing of high-viscosity silicone oil systems. This system avoids side reactions caused by local temperature differences and improves product quality stability.

  • • Vacuum degassing and impurity control

  • Equipped with a vacuum degassing system, it effectively removes low-molecular-weight byproducts and bubbles during the reaction process. Products achieve enhanced transparency and purity, making them suitable for high-end applications.

  • • Modular and customizable design

  • Silicone oil production line utilizes a modular structure, allowing configuration of units such as reactor, condenser reflux system, vacuum system, filtration unit and filling machine according to customer needs, facilitating futrue capacity upgrades and modifications.

  • • Safety and environmental advantages

  • Silicone oil production line features explosion-proof and leak-proof designs, complying with chemical production safety standards. Equipped with exhaust gas condensation recovery and waste liquid treatment systems, it reduces environmental emissions.
