The ultimate tensile strength of a material is an intensive property; therefore its value does not depend on the size of the test specimen.However, depending on the material, it may be dependent on other factors, such as the preparation of the specimen, the presence or otherwise of surface defects, and the temperature of the test environment and material.
Tensile strength (σ t) 52.8 to 185 MPa Tensile Elongation (%) ... The high ease of forming of LCPs is an important competitive advantage against other plastics, as ...
HDPE is known for its high strength-to-density ratio. [4] The density of HDPE ranges from 930 to 970 kg/m 3. [5] Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength (38 MPa versus 21 MPa) than LDPE.

The ASA mixtures have excellent rutting resistance and moisture damage resistance. The tensile strength ratio of the ASA and asphalt mixture are all larger than 0.8 and therefore satisfy the Superpave specification. The average coefficient of permeability of the ASA mixture is 6–10 times higher than the asphalt mixture in the same air void level.
Inert, thermally stable, tough and high tensile strength: Bottles, pipes, inner insulation (dielectric) of coax cable (see also PTFE), plastic bags, etc. Polypropylene: PP: Resistant to acids and alkalies, High tensile strength: Auto parts, industrial fibers, food containers, liner in bags, dishware and as a wrapping material for textiles and food
It is obtained by gradually applying load to a test coupon and measuring the deformation, from which the stress and strain can be determined (see tensile testing). These curves reveal many of the properties of a material, such as the Young's modulus, the yield strength and the ultimate tensile strength.
Compressive strength is a limit state of compressive stress that leads to failure in a material in the manner of ductile failure (infinite theoretical yield) or brittle failure (rupture as the result of crack propagation, or sliding along a weak plane – see shear strength). Tensile strength or ultimate tensile strength is a limit state of ...
The ASTM D638 is among the most common tensile testing protocols. The ASTM D638 measures plastics tensile properties including ultimate tensile strength, yield strength, elongation and Poisson's ratio. The most common testing machine used in tensile testing is the universal testing machine.
