5.33 Temperature dependence of flexural modulus (elastomer improvement) 5.32 Temperature dependence of flexural strength (elastomer improvement) 5.31 Temperature dependence of flexural modulus (high-filler PPS) 5.30 Temperature dependence of flexural strength (high-filler PPS) 5.29 Temperature dependence of flexural modulus (GF-reinforced PPS) 5.28 Temperature dependence of flexural strength (GF-reinforced PPS) Thus, it is suitable for products requiring flex resistance and sealability, such as wire coatings, tube products, and gasket parts. Flexural modulus, in particular, is calculated at exceptionally small deflections (under 0.1 mm). On the other hand, the flexural modulus of the unreinforced elastomer improvement type (including A670T05) is low at and near room temperature, and exhibits excellent flexibility. Flexural stress at break The flexural stress when a. Flexural strength The maximum flexural stress obtained during a bend test. A chord modulus can be fitted at those points on a flexural stress vs. For this reason, high-filler PPS grades that use cross-linked polymers (such as A310MX04) are well suited to applications that require a high elastic modulus in a high-temperature environment. Flexural modulus A function of flexural stress and flexural strain between 0.05 and 0.25 flexural strain. The cross-linked polymer type is excellent in terms of retaining its elastic modulus at high temperatures. The flexural modulus increases with the reinforcement content. The basic tendency of the temperature dependence of the flexural strength is the same as that of the tensile strength. The temperature dependence of the flexural strength of nine representative grades of TORELINA™ is shown in Figs. 5.27 Flexural strength/S-S curve (23℃, elastomer improvement PPS) 1.1 These test methods are used to determine the flexural properties of unreinforced and reinforced plastics, including high modulus composites and electrical. 5.26 Flexural strength/S-S curve (23℃, high-filler PPS) 5.25 Flexural strength/S-S curve (23℃, GF-reinforced PPS) 5.2 Flexural properties of TORELINA™ (23℃) I have often found myself in a situation where a datasheet states material strength and modulus as flexural or tensile sometimes both but at other times. A504X90 and A310MX03, which are both of the cross-linked polymer type, are notable in that they have a high elastic modulus relative to the linear polymer type. The S-S curves for six representative grades of TORELINA™ are shown in Figs. The vertical stress generated by this bending moment is called the "flexural strength." In the same way as for the tensile properties, the flexural modulus can be determined from the proportional limit of an S-S curve (flexural test) in accordance with Hooke's law (Formula 5.2). 5.24) In the 3-point flexural test where a vertical load is applied, the compression load associated with the deformation is generated on that side on which the test piece comes into contact with the indenter, whereas on the opposite side, a tensile load is generated, leading to a force (moment) that attempts to rotate the test piece. Flexural properties are determined using a simple-support, 3-point flexural test method, where the ends of the test piece are not fixed.
