Features

The duplex structure coat material's viscoelastic characteristics can be measured with a wide viscoelasticity ratio range, thanks to adaptable jigs.
An automatic switching function adjusts testing control from constant amplitude to constant load based on testpiece characteristics.
The frequency range spans 0.01 to 100Hz, with 137 measuring points. Vibration amplitude options include ±4 to ±160µm (01GP), ±8 to ±250µm (25GP), and ±500µm (optional *25GP).
Additionally, there are various optional functions like testing jigs, piezoelectricity measurement, stress/relaxation measurement, and creep testing.
The software provides features for optional items like master curves, activation energy, automatic/manual detection of tan δ (Tg), and manual detection of E' (Tg).

Overview
Specification

The DDV-25GP is designed for testing sheet, plate, and bar-shaped materials under high loads, while the DDV-01GP is intended for film, fiber, and paint film testing. These devices are non-resonance forced vibration viscoelastometers with a wide temperature range (-150°C to 400°C) and testing frequency options from 0.01 to 110 Hz, allowing for strain dispersion measurement.

During testing, these systems apply forced vibration strain to one end of the testpiece and provide data on complex modulus (E*), dynamic modulus of elasticity (E'), loss elasticity (E''), and loss tangent (tan δ) as functions of elasticity. This enables the evaluation of high polymer materials across a range of environmental temperatures.

RHEOVIBRON, a representative automatic measuring system for dynamic viscoelasticity, is widely used worldwide in research, development, and quality control for assessing material characteristics.
