Compound development
ERT is passionate and specialized in rubber compound development.
Our expertise and decades of experience are used to design, mix, test and optimize a recipe to achieve the desired material properties. The resulting intellectual property (recipes) and corresponding test results are shared with our customers. A basis for compound development can be:
Co-engineering
ERT develops a compound based on the client's set of requirements (e.g. application, processing, material specification, occupational and environmental aspects and price). A trial-and-error approach is also possible, for example if a customer needs a new rubber material, but does not exactly know what its required properties should be. In this case, a compound is worked on until the desired effect is achieved.
Reverse engineering
Based on in-depth chemical analysis of an existing product at ERT, a recipe will be developed that has equivalent or preferably improved materials properties. There are different compound mixing lines for black and colored compounds.
The tests are carried out as standard in accordance with ASTM, DIN and/or ISO standards. We can also meet any customer-specific test requirements.

Compound mixing (also multi-stage mixing) ISO2393
There are two mixing lines. One for carbon black-filled and one for coloured or mineral-filled compounds. The mixers are 1.6-litre laboratory scale Banbury-type mixers, with variable rotor speed, so that temperature during mixing can be controlled. Both the required force and the actual temperature of the mixer are recorded. ERT uses a fixed mixing scheme for most compounds, unless otherwise specified.
Mixing is carried out according to ISO standard 2393, unless otherwise specified.

Vulcanisation of test pieces and/or product prototypes ISO 2393
ERT has three electrically heated compression moulding presses with a 300x300mm plate. We have, of course, moulds available to manufacture all ISO-standardised test pieces. In addition, we can have simple one-off moulds made for small-scale prototype production.

Post-curing of test pieces and/or products
To finalize the vulcanization, rubber materials, in particular peroxide-cures, require post-curing after regular vulcanization in a production tool. The post-curing step extends the vulcanization degree and removes reaction products through evaporation.
