The DMTA system consists of a rheometer combined with the convection temperature devices CTD 450 and CTD 600 and a large variety of fixtures such as solid circular or rectangular fixtures, film and fiber fixtures or parallel-plate systems.
Features
 Whatever your DMTA requirements are and will be in the future, the DMTA system from Anton Paar is efficiently and comfortably adapted to meet your needs. The flexible software and patented features for convenient adaptation and use make sure of this. Use the system to analyze solutions, melts, solid bars, films, foils or reactive epoxy resins.

The wide temperature range of the CTD convection temperature devices (from –150 °C to 600 °C) allows you to perform DMTA on materials from the glassy to the molten state. Consequently, materials’ transition temperatures and relaxations are precisely determined. A large number of DMTA-related workbook templates is available, including analyses for the determination of transition points, slopes and more.
