Heat Build-Up Testing Module
Prevent Overheating of Your Rubber Components
A temperature rise in rubber is one of the main causes of material degradation and can ultimately lead to fatigue cracking.
For rubber products such as tires, belts, and vibration dampers, Heat Build-Up (HBU) is a critical design parameter that must be carefully verified and well controlled.
The Metravib Heat Build-Up Module is a powerful extension of the DMA+ Series, designed to accurately analyze the thermal response of rubber compounds under repeated mechanical excitation and advanced test conditions.
Key Benefits:
- Early detection of overheating tendencies in elastomer components
- Realistic test conditions with adjustable parameters
- Quantitative evaluation of heat generation under cyclic loading
- Essential for material selection, design validation, and service life prediction
With the Heat Build-Up Module, Metravib offers a reliable tool for optimizing the thermomechanical performance of your products – ensuring greater safety, durability, and efficiency.

Heat Build-Up Testing Module Systems
Testing Under Realistic, Application-Oriented Conditions
With Metravib's Heat Build-Up testing modules, it's possible to go far beyond the standard testing conditions defined by ISO 4666 or ASTM D623.
Unlike the traditional Goodrich Flexometer, which operates solely with a sinusoidal deformation, Metravib’s MULTITEST system offers a multi-harmonic waveform control mode that opens up a wide range of advanced testing possibilities.
Your Benefits with MULTITEST:
- Flexible selection of excitation waveforms:
- Sine, Haversine, Rectangular, Pulse, or even custom-defined signals
- Simulation of real-life load scenarios as encountered in actual applications
- High repeatability and realistic evaluation of heat build-up
- Ideal for optimizing material selection and component design
Whether for tires, seals, or vibration isolators – Metravib’s Heat Build-Up modules allow for testing rubber components under real-world thermal-mechanical stress conditions.
