Difference between silicone oil and silicone polymers with examples
Accepted Answer
Silicone oil and silicone polymers are both based on siloxane chains (Si-O-Si), but differ in their molecular structure and properties.
Silicone oil is a low-molecular-weight, linear siloxane fluid. It's known for its low viscosity, high thermal stability, and water repellency. Examples include:
Dimethicone (used in cosmetics and hair care products)
Polydimethylsiloxane (found in lubricants and sealants)
Silicone polymers are high-molecular-weight, branched or crosslinked siloxane chains. They exhibit rubber-like properties and are used in a wide range of applications. Examples include:
Silicone rubber (used in gaskets, seals, and medical devices)
Silicone resins (found in coatings, adhesives, and sealants)
