How silicones can be adjusted to maximize compatibility and performance ... and even behave in seemingly "unsilicone" ways.


Did you know ... by changing the size or structure of the silicone molecule or by adding different functional groups to it, you can enhance or change the way it behaves! Think you know silicones? Think again!

Property and performance modification – the secret to silicone’s amazing versatility

Silicone chemistry enables the development of incredibly versatile and adaptable products:

  • From rubber flippers for swimming in the ocean to underarm deodorants for sensitive skin
  • From paints and lubricants that can withstand extreme heat, to sealants that maintain their flexibility in the arctic cold

Open the silicone showcase to learn more about the many applications for silicone materials.

Why are silicones so adaptable? Because there are so many ways to tailor or modify their properties and performance abilities!

The silicone material matrix

Every silicone is a unique combination of molecular weight, structure, functionality, and delivery system. By manipulating these variables, silicone scientists can create an infinite variety of problem-solving and innovation-enabling materials.

The four ways silicones can be modified: molecular weight, organic functionality, polymer structure, and delivery system

How silicone scientists create the ideal material for your application

  • Modify the molecular weight and viscosity by changing the degree of polymerization or by blending different viscosities of silicone fluids together.
  • Give the material a different structure - make it cyclic, linear, resinous, or crosslinked.
  • Add different organic functionalities to create organically modified silicones - "super" silicones capable of extending silicone performance to organic substrates and systems.
  • React two different silicone building blocks together.
  • Change the delivery system from silicone to aqueous, solvent, compound, or solid via a variety of finishing processes.

Learn more about the different forms of silicone.

Did you know ... all silicones are not created equal. Any two silicone sealants, elastomers, or fluids, for example, can have very different physical and performance properties, depending on their functionality, how they are polymerized and finished!
