Digestive tract contamination and systemic toxicity due to the leakage of breast implant filler to the breast milk are the principal infant health concerns with breast implants. Breast implant fillers are biologically inert: silicone filler is indigestible and saline filler is mostly salt and water. Each of these substances should be chemically ...
A breast implant is a prosthesis used to change the size, shape, and contour of a person's breast.In reconstructive plastic surgery, breast implants can be placed to restore a natural looking breast following a mastectomy, to correct congenital defects and deformities of the chest wall or, cosmetically, to enlarge the appearance of the breast through breast augmentation surgery.
Silicone caulk can be used as a basic sealant against water and air penetration. In organosilicon and polymer chemistry, a silicone or polysiloxane is a polymer composed of repeating units of siloxane (−O−R 2 Si−O−SiR 2 −, where R = organic group). They are typically colorless oils or rubber-like substances. Silicones are used in ...
Silicone rubber is an elastomer composed of silicone—itself a polymer—containing silicon together with carbon, hydrogen, and oxygen. Silicone rubbers are widely used in industry, and there are multiple formulations. Silicone rubbers are often one- or two-part polymers, and may contain fillers to improve properties or reduce cost.
U.S. Army Public Health Center Toxicology Lab technician assessing samples. Toxicology testing, also known as safety assessment, or toxicity testing, is the process of determining the degree to which a substance of interest negatively impacts the normal biological functions of an organism, given a certain exposure duration, route of exposure, and substance concentration.
Poly Implant Prothèse (PIP) was a French company founded in 1991 that produced silicone gel breast implants.The company was preemptively liquidated in 2010 following the revelation that they had been illegally manufacturing and selling breast implants made from cheaper industrial-grade silicone since 2001 (instead of the mandated medical-grade silicone they had previously used).

Silicone rubber applications such as catheters are widespread in medicine, but have several limitations. For example, they exhibit poor tear strength and poor resistance to fatigue . Brittle fracture can occur from defects within sections owing to poor control of vulcanization . [ 2 ]
