Modulus elongational

Figures 10-14 illustrate the reductions obtained in hardness, 50% modulus, 100% modulus, elongation, and tensile strength, respectively, for a fluoroelastomer compound produced under normal production conditions. Table 1 shows the improvement obtained in detail.

Extensive product trials using the LCBM technique in standard tire recipes have proved that the tensile strength and modulus, elongation at break, compound hardness, abrasion loss, and hot air aging properties have improved substantially compared to mixes prepared using conventional technique. 

Weibull plots of various fibre properties, such as the filament count, modulus, elongation at break and the strength, can provide important information on the quality and performance of the manufacturing process. The results can be used to formulate a strategy for the improvement of the yarn properties. 

The modulus, elongation to break, ultimate strength, and toughness of the straight castor oil elastomers increase with increasing amounts of TDI employed as crosslinker. A similar trend was observed in the elastomeric SIN s (40% elastomer content) in which the elastomer phase was continuous. 

Elastic modulus was measured by a dynamic method at 160 °C. on samples with 2-inch bench marks elongated at a constant rate of 100% per minute. The stress at strains of 25, 50, 75, and 100% was used to calculate Youngs modulus. Elongation at rupture at 160°C. was measured at the same relative rate of elongation, the mean of four measure-...

Coherently, as expected for immiscible blends, Tg values measured by DSC show very small variations with respect to the pure components while the mechanical properties degrade with respect to neat sPS. In particular, for minimum polyolefin contents <40 wt%, uniaxial tensile tests revealed a decrease in Young s modulus, elongation at break and energy to break. For higher contents, a phase inversion of the morphology occurs and the blend properties approach progressively those of the pure polyolefins. 

We have used X-ray methods to compare the crystallite size of RIM specimens prepared with and without use of a polyether diamine (PEDA) additive. These results are compared with differential scanning calorimetry data on the hard domain melting behavior and dynamic-mechanical studies of the extent of phase separation. Mechanical data on flexural modulus, elongation, impact strength, and heat sag behavior have been obtained for the same specimens and have been correlated with the structural analyses. 

Results and Discussion. X—ray diffraction densitometer scans are presented In Figures 2 for the 18 EG and Figure 3 for the 30 EG series for RIM polyurethanes. DSC and Storage Modulus traces (El) for the same specimens are shown In Figures 4, 5 and 6, and flexural modulus, elongation, Impact strength, and heat sag data are given In Table I. 

Initial studies on PU1478 materials showed effects on physical properties of plaque thickness and System Index used during RIM processing. Typical tensile stress-strain data are given in the first 4 columns of Table III. Increases, particularly in modulus, elongation... 

The tensile strength, modulus, elongation, tear and hardness properties of the radiation crossllnked CPE compounds are shown in Table III. In general excellent properties are developed with radiation curing. In Rad 4 it is evident that the addition of dehydrochlorlnation stabilizers leads to slight degradation in the mechanical properties of the polymer.

Flexural modulus is a measure of the strength of adhesives. Modulus data are most often used in stress analysis (one-dimensional or as an input to 3-D modeling). In addition to flexural modulus, elongation-at-break is also recorded. The standard test...
