👉 Polyimide is a type of plastic that consists of two or more monomers (polymer units) connected together by hydrogen bonds. It has excellent mechanical strength, high melting point, and low thermal expansion, making it suitable for use in various applications such as electronics, medical devices, and aerospace components. Polyimides are typically made from a combination of three or more monomer chains that are joined together to form a single polymer unit. The structure of these polyimides can be arranged in
