The dependence of the storage modulus (E') and the loss angle
tangent (tan 6) on temperature for SF/PU blend fibrous membranes are shown in Fig.
1A and 1B, respectively) as well as the capacitance of a capacitor with specimens representing its dielectric and the corresponding values of tangens of the loss angle

10 that the value of loss angle
tangent of PP prepared under same vibration frequency (10 Hz) is decreasing with the increasing vibration pressure.
The UR-2070 oscillating disk rheometer tests for elastic torque, viscous torque, elastic and viscous complex curve, tan delta curve, loss angle
curve, cure rate curve and test temperature curve, according to the literature.
15,: (i) where cotan [delta] is the cotangent of the loss angle
of a sample of said polyisoprene, measured at 130[degrees]C.
The dielectric measurements (dielectric constant [epsilon], tangent of the dielectric loss angle
tan [delta]) were performed with the Q-meter BS-3R (Shanghai, China), and the dielectric parameters were calculated using the formulas 
The glass transition (Tg) measurement precision of the Metravib DMA is said to result from many technical innovations and specificities, including auto-calibration of the loss angle
measurement, quality of the thermal control and precise control of dynamic test conditions.
0] is the amplitude of strain [-], [Omega] is the angular frequency of the driving force [rad/s], E is the modulus of the plastic [Pa], and [Delta] is the loss angle
of the plastic.
If a cyclic deformation is applied to a rubber, the rubber has both viscous and elastic components, and the loss angle
is the phase angle between these two components.
Elastosil R 752/50, for example, is suitable for low-modulus damping elements with particularly low rebound resilience (35%) at a loss angle
of 13 [degrees].
