Highly transparent silicone materials

摘要

Silicone based polymers possess a unique set of properties that makes them highly suitable for optical applications. In addition to their excellent thermal stability, mechanical properties, and ease of processing, they are highly transparent in the ultraviolet, visible, and selected bands of the near-IR spectra. The loss and absorption characteristics for a variety of silicone based polymers are examined and an example of a recently developed ultra-violet transparent polymer coating that is UV cured illustrates the flexibility of the silicone polymer family to be tailored to meet specific application needs.
