RHEOVIBRON Automatic Dynamic Viscoelastometer

• 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 method can be applied in accordance with shape and elasticity of test piece.
• High load system DDV-25GP for test piece of sheet, plate and bar shapes
  Fine load system DDV-01GP for test piece of film, fiber and paint film
• This device is one of the simplest and the orthodox-system dynamic visxoelastometers of non-resonance 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. Further, many data from one test piece 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 vibration strain to one end of test piece, compute 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 test piece. These functions of high polymer materials are measured continuously varying from low to high environmental temperature and the material characteristics a can be accurately and easily evaluated.
• RHEOVIBRON, as a representative automatic measuring system of dynamic viscoelasticity, is being used in various countries for many years in the fields of research and development for dynamic characteristics and quality inspection control.
