What Is Medical Grade Silicone

1. Medical-grade silicone

Silicone is a versatile material that can be used for a ton of stuff, including things like medical implants. ‘Medical-Grade’ means the silicone has been tested and approved by the FDA for biocompatibility – so it’s designed to be worn safely inside the body for long periods of time. Medical grade silicone is hypoallergenic, latex-free and contains no toxins, and is also nonporous and so resists bacterial growth.

Medical-grade silicones are silicones tested for biocompatibility and are appropriate to be used for medical applications. In the United States, the Food and Drug Administration (FDA) Center for Devices and Radiological Health (CDRH) regulates devices implanted into the body. It does not regulate materials other than certain dental materials. The FDA regulates silicones used in food contact under the auspices of the Center for Food Safety and Nutrition (CFSAN) and for use in pharmaceuticals under the auspices of the Center for Drug Evaluation and Research (CDER).

Medical-grade silicone is a class of clinically-tested products designed to interact safely with the human body in a medical setting. The many uses and forms of medical silicone make it difficult to define and classify. But before it can be applied medically, it must pass rigorous FDA standards. Because medical silicone is safe and durable, it can be engineered for short-term or long-term use. Such items like tubes, dental retainers, implants, respiratory masks, and gel sheets for scar therapy all contain medical-grade silicone.

Medical-grade silicones are generally grouped into three categories: non-implantable, short-term implantable, and long-term implantable. Materials approved as Class V and VI can be considered medical grade. Most medical-grade silicones are at least Class VI certified.

2. Why is Silicone good for Medical Applications

• Silicone is a biocompatible material
