Standard Guide for Silicone Elastomers, Gels, and Foams Used in Medical Applications Part I - Formulations and Uncured Materials
1.1 This guide is intended to educate potential users of silicone elastomers, gels, and foams relative to their formulation and use. It does not provide information relative to silicone powders, fluids, or other silicones. The information provided is offered to guide users in the selection of appropriate materials, after consideration of the chemical, physical, and toxicological properties of individual ingredients or by-products. This guide offers general information about silicone materials typically used for medical applications. Detail on the crosslinking and fabrication of silicone materials is found in Part II of this guide.

1.2 Fabrication and properties of elastomers is covered in the companion document, F2042. This monograph addresses only components of uncured elastomers, gels, and foams.

1.3 Silicone biocompatibility issues can be addressed at several levels, but ultimately the device manufacturer must assess biological suitability relative to intended use.

1.4 Biological and physical properties tend to be more reproducible when materials are manufactured in accordance with accepted quality standards such as ISO 9001 and current FDA Quality System Regulations/Good Manufacturing Practice Regulations (21CFR, Parts 210, 211, and 820).
