A step forward for the R&D laboratory

In the rubber processing sector, accurately understanding the behaviour of

compounds during vulcanisation is key to ensuring the quality, repeatability and

performance of the final components.

To further strengthen its research and development activities, GB has recently

introduced a new MDR – Moving Die Rheometer – into its R&D laboratory, an

advanced instrument designed to analyse the rheological behaviour of rubber compounds

during the vulcanisation process.

This technology allows for the highly precise study of how the compound

reacts to temperature and mechanical stress, providing essential data for

understanding and optimising the moulding process.

 

What is a Moving Die Rheometer

The Moving Die Rheometer (MDR) is an instrument used in research and quality control laboratories to monitor the cross-linking process of rubber. During the test, the compound is

subjected to controlled conditions of temperature and strain, allowing observation of

how the material’s structure evolves over time.

By analysing the vulcanisation curve, it is possible to identify key parameters

for the behaviour of the compound and for the stability of the production process.

 

The benefits for compound analysis

Thanks to the new MDR, the GB laboratory can analyse and verify with greater precision

various aspects of the behaviour of rubber compounds, including:

• the compound’s vulcanisation curve
• the onset of cross-linking (scorch time)
• optimal vulcanisation time
• rheological behaviour of the material during the process
• consistency between different batches of compound

This information provides a more comprehensive understanding of the material’s

characteristics prior to the production phase.

 

Greater reliability for production processes

The introduction of this instrument represents a significant step forward in the control of

compounds and in the ability to support production processes. Thanks to the data collected via the Moving Die Rheometer, it is possible to assess material performance more accurately

and identify any variations before they can affect production.

This approach improves the stability of moulding processes and ensures

greater consistency in the characteristics of the components produced.

 

Research and development serving the rubber industry

The integration of new technologies into the R&D laboratory forms part of GB’s ongoing investment in research and development, with the aim of complementing production with

increasingly advanced technical support.

Having tools such as the Moving Die Rheometer means being able to analyse compounds in greater depth, helping to develop reliable solutions and supporting customers

in the production of ever-higher-performance rubber components.
