• Polysiloxanes are a group of silicon-based polymers, which are used extensively throughout the body in the breast, ear, chin, and nose implants for reconstructive surgeries, as well as in formulation as adhesives, elastomers, and gels.
• Polysiloxanes are widely used for medical applications and have a long success record. Material types include elastomers, gels, lubricants, foams and adhesives. Polysiloxanes are very chemically stable and unreactive. They are very hydrophobic and have a low moisture uptake. They have good electrical insulation characteristics. Nearly all polysiloxanes are based on polydimethylsiloxane.

Polysiloxanes are the polymer of choice for long-term use in the body where an elastomer is required and where there is a demand for bio-durability and bio-compatibility Polysiloxane gels, combining the high oxygen permeability of silicone and the comfort and clinical performance of conventional Polyacrylate Hydrogels, enabled the fabrication of soft, gas permeable contact lenses for extended wear.
