Webshows the range of E-modulus of TPU and RTPU in comparison to other materials. The modulus of elasticity (E-modulus) is determined by tensile testing according to DIN EN ISO 527-1A, using a test specimen at a testing speed of 1 mm/min. The E-modulus is calculated from the initial slope of the stress-strain curve as ratio of stress to strain. WebThe most common types of high-performance polyethylene fibers are Dyneema and Spectra. These are produced as multifilament yarns of a wide range of denier per filament (dpf) from 0.3 to 10 dpf. The tenacity of a single filament can be greater than 3 N/tex, and the modulus can be greater than 120 N/tex (see Table 8.4).
