20kN macromolecule material testing machine is used for mechanical test and research with rubber, fiber plaster, macromolecule adhesive coating, macromolecule based fiber reinforced composite material, polypropylene composite material. it is test for compounding mechanical property, such as tensile strength, tensile stress, tearing property, elongation, peeling strength, stressed elongation, yielding elongation and so on. there are important index of macromolecule material, such as tearing and peeling adhesive strength, tensile yield stress, yield strain, breaking strain, elasticity modulus, Poission’s ratio.
