So, you know how sometimes you might get a boo-boo and need a band-aid to cover it up? Well, sometimes people need something called a medical device to help them feel better.
Medical devices can be things like pacemakers, catheters, or even prosthetic limbs. And sometimes, these devices are made out of a special type of material called medical grade silicone.
Silicone is kind of like a stretchy, rubbery material that is really good at being flexible and tough at the same time. But not all silicone is the same - some kinds of silicone might have chemicals in them that wouldn't be very good for medical devices.
That's why medical grade silicone is used instead. It's a special kind of silicone that has been tested really carefully to make sure it doesn't have any bad chemicals in it that could hurt people.
So, medical grade silicone is a really safe and strong material that doctors and scientists use to make important things that can help people feel better.
