Ethylene-vinyl acetate (EVA) is a type of plastic that is known for its flexibility and durability. It is made by combining two materials: ethylene, a gas that is commonly used in making plastics, and vinyl acetate, which is a liquid used in adhesives and paints. This combination results in a material that is soft, rubbery, and resistant to UV light and weather, making it ideal for various applications. EVA is widely used in products like foam padding, shoe soles, and adhesives. Its lightweight nature and ability to absorb shock make it popular in sports equipment and packaging. Additionally, EVA is often used in the production of solar panels due to its excellent sealing properties, helping to protect the components inside.
