Laboratory tests

A professionally equipped laboratory and experienced laborers

Supplementary tests of elastomer compounds

At your request, Silspek Rubber can carry out paid supplementary tests of selected elastomer compound. Tests can be carried out both based on the material of our production and entrusted to external production.

Thanks to the professionally equipped laboratory and experience of our laborers, we can successively carry out even the most demanding orders.

Below we present the scope of selected analyzes that are included in the offer range of our laboratory. If you are looking for specific tests, please contact our sales office to determine the details of the test.
