When properly prepared, the benefits include fulfillment of USP Class VI and ISO 10993 requirements, and can be sterilized with autoclave, gamma, ETO. Less than 30 day implant and long-term implant grades available. Medical grade pigments are also available.
Limitations: Generally, low abrasion and tear resistance, and high friction characteristics preclude silicones from effectively sealing some dynamic applications. Silicones are also highly permeable to gases and are generally not recommended for exposure to ketones (MEK, acetone) or concentrated acids.
