Dimethyl Silicone Oil (PDMS), also known as silicone oil, is a cornerstone material in many industrial applications due to its exceptional properties. Among these, viscosity plays a crucial role in determining its performance characteristics and suitability for specific uses. Understanding how different viscosities of PDMS function is key to optimizing your formulations and manufacturing processes. At NINGBO INNO PHARMCHEM CO.,LTD., we specialize in providing a comprehensive range of PDMS fluids, allowing you to purchase the exact grade you need.

The viscosity of Dimethyl Silicone Oil refers to its resistance to flow. This property is directly related to the molecular weight and chain length of the polymer. Lower viscosity fluids are more fluid and spread easily, while higher viscosity fluids are thicker and provide more substantial lubrication or damping effects. As a leading manufacturer and supplier in China, we offer a spectrum of viscosities, from low-viscosity options ideal for sprayable lubricants and defoamers to high-viscosity fluids sought after for heavy-duty lubrication and sealing applications. This ensures you can buy the perfect silicone oil for your industrial use.

Low Viscosity PDMS (e.g., 10-100 cSt):

Fluids in this range are typically very fluid and have low surface tension. They are excellent for applications where easy spreading and penetration are required:

  • Release Agents: Low viscosity PDMS is effective in mold release applications for plastics and rubber, preventing sticking and ensuring clean finishes.
  • Defoamers: Its ability to rapidly spread and break foam makes these grades ideal for controlling foam in industrial processes.
  • Light Lubrication: For applications requiring a light, non-greasy lubricant, such as in some cosmetic formulations or precision instrument components.
  • Textile Finishing: Used to impart softness and improve the hand feel of fabrics.

Medium Viscosity PDMS (e.g., 100-1000 cSt):

This range offers a balance of flowability and film-forming properties:

  • General Purpose Lubrication: Suitable for a broader range of mechanical parts and equipment.
  • Cosmetic Ingredients: Often used in skincare and hair care products for its emollient properties and ability to provide a smooth feel. We are a key supplier of PDMS for cosmetics.
  • Paint Additives: Used to improve flow, leveling, and surface properties of coatings.

High Viscosity PDMS (e.g., 1000 cSt and above, up to 1,000,000 cSt):

These fluids are significantly thicker and provide enhanced lubrication, damping, and sealing capabilities:

  • Heavy-Duty Lubricants: Ideal for demanding applications where durability and long-lasting lubrication are critical.
  • Hydraulic Fluids: Their compressibility and thermal stability make them suitable for hydraulic systems.
  • Damping Fluids: Used in shock absorbers and damping devices where stable performance across temperature variations is needed.
  • Sealants and Gaskets: High viscosity PDMS can be formulated into sealing compounds.
