Density (g/cm³) For a homogeneous object, Density = Mass Divided By Volume. The higher the density, the tighter the particles are packed inside the substance. The Specific Gravity is the ratio of Density of the material to the Density of water at a specified temperature. It is common to use the density of water at 4°C as reference - at this point the density of water is at the highest i.e. 1 g/cm3. So Specific Gravity of less than “1” means that the material will float in water.

Tensile Strength (Mpa) Tensile strength is a property of a material that measures the force required to pull something to the point where it breaks. Tensile strength is important for a material that is going to be stretched or under tension. In many brittle materials such as rock, concrete, cast iron, tensile strength is almost negligible.

Elongation at break (%) The elongation at break is the strain on a sample when it breaks. This usually is expressed as a percent. The elongation at break sometimes is called the ultimate elongation. Fibers have a low elongation-to-break and elastomers have a high elongation-to-break

Flexural Strength (MPa) The flexural strength of a material is its ability to resist deformation under load, or how much you can bend the material before it starts to break. Skis, fishing rods, pole vault poles and diving boards are examples of parts needing high flexural strength.

Coefficient of Friction(C)The coefficient of friction, or COF, is described as the ratio of the force of friction between two bodies and the force pressing them together. A lower friction coefficient indicates that the surfaces are slicker - there is less resistance to the sliding motion.
