Silicone Contact Lenses
Our silicone chemistry expertise, rigorous quality control systems, extensive analytical capabilities and versatile manufacturing assets combine to make SiVance a preferred partner for silicone hydrogel contact lens manufacturers.
A key property of silicone is improved oxygen permeability and biocompatibility. Because the cornea of the eye gets oxygen directly from the air, it is important for oxygen to pass readily through the contact lens. Our precision silicone materials are critical in allowing oxygen to efficiently pass through the latest generation of contact lens to the cornea.
Precursors for TRIS and its Derivatives
SiVance provides various basic building blocks for the production of standard hydrogel materials being employed today, including 3-(Methacryloyloxy)propyltris(trimethylsiloxy)silane, Tris(trimethylsiloxy)-3-(methacryloxy)propylsilane and 3-[Tris(trimethylsiloxy)silyl]propyl methacrylate.
Other Optical Applications
Our silicone technology can be tailored to deliver precise refractive indices and viscosities while providing other properties including thermal resistance, improved gas permeability, and dielectric strength. These materials can be used some of the most demanding optical applications.
SiVance has a proven and confidential track record of custom manufacturing silanes and silicones to customer’s exact specifications. If you don’t see what you need, please contact us.
