2016/03/25· Tensile strength, elongation, and modulus are often used as qualifiion criteria when specifying rubber and polyurethane material. They can also serve as control criteria when testing finished products, such as tubes and straps. These three material physical property concepts can easily be confused. Let’s try to keep this as simple as possible.
