Butyl rubber is a special kind of material that is used to make things that need to be strong and stretchy. Think of it like a stretchy balloon! Butyl rubber is made up of tiny molecules that link together to make long chains.
These chains are then molded and pressed into different shapes, like a tire or a seal. Because it is so strong and stretchy, butyl rubber is often used in things like tires for cars and bicycles, as well as in seals for doors and windows to keep out air and water.
Butyl rubber is also very resistant to damage from things like sunlight and chemicals, which makes it great for outdoor use. Overall, butyl rubber is a very useful material that helps make many of the things we use every day strong and long-lasting!
