For measurement of the dynamic modulus of viscoelasticity of high polymers like plastic, rubber and complex material, tensile method, shear method and 3-point bending methoud can be applied in accordance with shape and elasticity of testpiece.
This device is one of the simplest and the orthodox-system dynamic visxoelastometers of non-rssonance forced vibration method. The wide temperature range (-150 degree Celsius to 400 degree Celsius) and forced vibration method enables optional selection of testing frequency within 0.01~110 Hz and also measured of strain dispersion. Furhter, many data from one testpiece can be obtained due to possible switching for constant amplitude control or constant load control and wider range of measurement.
At the testing, applying forced vibaration strain to one end of testpiece, ccompute and output the complex modulus (E*), dynamic modulus of elasticity (E'), loss elasticity (E'') and loss tangent (tan δ) which are elasticity function from stress appeared on the testpiece. These functions of high polymer materialas are measured continuously varying from low to high environmental temperature and the material characteristics acan be accurately and easily evaluated.
RHEOVIBRON, as a representative automatic measuring system of dynamic viscoelasticity, is being used in various contires for many years in the fields of research and development for dynamic characteristics and quality inspection control.
