Its ultimate tensile strength of 70 MPa (10152.6 psi) is the greatest of any of our polycarbonates, and its yield tensile strength of 63 MPa (9137.38 psi) lags only behind that of the Trupoly. It's unlike those two, however, in the sense that its tensile strength is measured by MPa instead of psi. UV2 polycarbonate is similar to SL and Trupoly in the sense that it's mainly used for clear sheeting. Trupoly is also somewhat unusual in that its yield tensile strength (9400 psi) is greater than its ultimate tensile strength (8800 psi), meaning that a sheet made from this material will break before it suffers permanent deformation. Trupoly is an alternative for those in need of clear polycarbonate sheeting, a product that offers exceptional protection for machine guards, freight doors, or any other environment where you need both transparency and durability. Its ultimate tensile strength of 9500 psi and yield tensile strength of 9000 psi means that it would be able to withstand the pressure of being approximately 20,000 feet underwater before suffering permanent deformation or breakage. Our clear SL polycarbonate sheets provide the transparency of glass in concert with superior impact resistance and tensile strength. Though all varieties of polycarbonate exhibit exceptional tensile strength, the actual numbers vary somewhat from product to product. Now that you know the basics of tensile strength, you're likely curious as to just how well polycarbonate sheet performs in that area. Imagine how disastrous it would be if it was discovered halfway through the creation of a building that a selected material couldn't handle the pressure of the weight piled on top of it. It's essential for manufacturers to be aware of these numbers when choosing materials, especially when it comes to construction projects. The former marks the amount of pressure that a material must undergo before it breaks, while the latter dictates the pressure it can withstand before suffering permanent deformation. It's also important to note that both tests measure tensile strength in two ways ultimate tensile strength and yield tensile strength. One MPa is equal to 145.038 psi to get a better sense of what the readings mean, check out this chart and its collection of pressure readings for everyday environments and occurrences. Depending on the test, tensile strength can be measured in psi, or pounds per square inch (for ASTM tests), or in MPa, or Megapascals (for ISO tests). Though these elements are all of importance, tensile strength is often used as the basic determiner of a material's ability to hold up under stress. From this, testers can not only derive the tensile strength of said material but also the strain, the tensile modulus, the yield point, the break point, and Poisson's ratio. This illustration may give you a better idea of how the test looks and of the equipment involved. Though there are minor differences between the tests, both operate on the same basic principle of both ends of a material sample being secured by specially-designed clamps and pulled apart until the material breaks. It dictates how well a material can handle being pulled apart or otherwise stressed and is typically derived from either a ASTM D638 or ISO 527 test. Tensile strength, simply put, is a measurement of a material's ability to resist breaking under tension. But what is tensile strength, and why is it important in a material? Tensile Strength Basics Lost in all these features, however, is the fact that polycarbonate sheeting also boasts tremendous tensile strength more than double that of glass in most cases. This is thanks in part to its outstanding impact resistance (250 times greater than that of glass) and its ability to resist temperatures of up to 240 degrees Fahrenheit. Polycarbonate sheeting is known throughout the world of architecture and construction as one of the strongest and most flexible materials on the market today.
