These internal forces arise as a reaction to external forces applied to the body. When selecting a material, consider the material properties, manufacturability characteristics, cosmetic appearance, and cost. 1 Natural rubber is widely used in shock and vibration isolators because of its high resilience (elasticity), high tensile and tear properties, and low cost. The Tests In Test Method A , a die cut “dumbbell” shaped piece of glove material is stretched from either end by a machine at a constant speed until it breaks. The 14 indicates that the tensile strength must be at least 14 MPa, or 2032. Tensile Strength Change %-22. It also features good resistance to ozone and operates in temperatures as low as -22°F and as high as 230°F. What is Shore Hardness and how is it measured? Shore Hardness is measured using a durometer gauge, which uses a spring loaded steel rod to compress the surface of the sample and provide a reading. Find out more about these products here. Stainless Steels. Natural Rubber is refined from sap o f rubber trees. MATERIALS SCIENCE AND ENGINEERING – Vol. But this is not the case. Tensile strength measures the force required to pull something such as rope, wire, or a structural beam to the point where it breaks. Table 1 summarizes the distribution of orientations, heat treatments across the three build rounds. An O-Ring is one of the most common types of seals in the world.
