List of some addition polymers and their uses Polymer Abbreviation Properties Uses Low-density polyethylene: LDPE: Chemically inert, flexible, insulator: Squeeze bottles, toys, flexible pipes, insulation cover (electric wires), six-pack rings, etc. High-density polyethylene: HDPE: Inert, thermally stable, tough and high tensile strength
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.
There are many properties of polymeric materials that influence their mechanical properties. As the degree of polymerization goes up, so does the polymer’s strength, as a longer chains have high Van der Waals interactions and chain entanglement. Long polymers can entangle, which leads to a subsequent increase in bulk modulus. [11]
A material property is an intensive property of a material, i.e., a physical property or chemical property that does not depend on the amount of the material. These quantitative properties may be used as a metric by which the benefits of one material versus another can be compared, thereby aiding in materials selection.
BoPET (biaxially oriented polyethylene terephthalate) is a polyester film made from stretched polyethylene terephthalate (PET) and is used for its high tensile strength, [1] chemical stability, [1] dimensional stability, [2] transparency [1] reflectivity, and electrical insulation. [1] When metallized, it has [3] gas and moisture barrier ...
Tensile strength: Similar, on average, to the polypropylene's fibers. [clarification needed] Elastic modulus: Cellulosic fibers have a low modulus of elasticity. This determines its use in building components working in post-cracked stage, with high energy absorption and resistance to dynamic forces. [clarification needed]
The tensile strength of a material quantifies how much elongating stress the material will endure before failure. [49] [50] This is very important in applications that rely upon a polymer's physical strength or durability. For example, a rubber band with a higher tensile strength will hold a greater weight before snapping.
This synthetic polymer material was invented and developed by SRI International in the 1980s and manufactured by Toyobo. [2] In generic usage, the fiber is referred to as PBO. [3] Zylon has 5.8 GPa of tensile strength, [4] which is 1.6 times that of Kevlar. Additionally, Zylon has a high Young's modulus of 270 GPa, meaning that it is stiffer ...
