What is polyurethane membrane made of

Polyurethane membranes are typically made of a type of polymer known as polyurethane. Polyurethane is a versatile synthetic material that is formed by the reaction of polyols (a type of alcohol) with diisocyanates (compounds containing isocyanate groups). The resulting chemical reaction produces a polymer with a wide range of properties, including flexibility, durability, and resistance to water and chemicals.
Polyurethane membranes used in various applications, such as waterproofing, roofing, and medical products, are typically manufactured through a process called casting or extrusion. The specific composition and additives used in polyurethane membranes can vary depending on their intended application. For example, additives may be included to enhance UV resistance, fire retardancy, or elasticity.
