DMA EPLEXOR® up to 500 N
High-Force DMA
The testing instruments of the DMA GABO EPLEXOR® series up to ±500 N enable the dynamic mechanical (or static) characterization of a wide range of different materials including elastomers and polymers, composites, metals, glasses, ceramics, biomaterials and foods, adhesives, and liquids.
The modular design of the high-force DMA systems allows for measurements in the tension, compression, bending and shearing modes. The testing machines in this series differ from each other mainly in terms of their maximum dynamic force ranges of ±25 N, ±100 N, ±150 N and ±500 N.
Various add-on options make these testing machines a safe investment for the long-term.
All testing machines in this series are conform to standards such as DIN 53513, ISO 6721/1, ISO 6721/4, ISO 6721/5, ISO 6721/6, ISO 4664, ASTM D4065, and ASTM D4473.

CreepCreep describes a time and temperature dependent plastic deformation under a constant force. When a constant force is applied to a rubber compound, the initial deformation obtained due to the application of the force is not fixed. The deformation will increase with time.creep, RelaxationWhen a constant strain is applied to a rubber compound, the force necessary to maintain that strain is not constant but decreases with time; this behavior is known as stress relaxation. The process responsible for stress relaxation can be physical or chemical, and under normal conditions, both will occur at the same time. relaxation, fatigue, heat build-up, Curing (Crosslinking Reactions)Literally translated, the term “crosslinking“ means “cross networking”.
