Elastocon's experts will be present at the K-fair in Düsseldorf 19–26 October 2022. We will present, among other things, our proprietary stress relaxation test system for continuous measurement of rubber in either compression or tension according to ISO 3384, ISO 6914 and ASTM D6147 and other technically equivalent standards.
In stress relaxation testing, a sample is compressed between two plates, usually 25%. Alternatively the sample is elongated, usually 50%. In the test rig, the force and temperature are measured, which are registered continuously. The test usually takes place in air at a suitable aging temperature for the material. It can also be performed in elongation and in different types of liquids, as well as in stable or cycling temperature. We can offer different solutions for temperatures from -70 °C to +300 °C.
The decrease in force during stress relaxation testing correlates well with the reduction of elongation at break in an aged tensile test. But with stress relaxation testing, you can continuously follow the decrease in force during the time that the material ages.

We will also show our rigs for compression set (EV 03), and tension set (EV 04).
The EV 03 rig is used for the determination of the compression set characteristics of vulcanized and thermoplastic rubbers at ambient or elevated temperatures according to ISO 815-1.
With the EV 04 rig you can easily perform tension set tests according to standard ISO 2285, for determining the dimensional changes in test pieces of vulcanized or thermoplastic rubber during and after tensile loading for relatively short periods under constant elongation or constant loading.
Both rigs works well in all our ageing ovens for precision ageing of rubber and plastic materials, but also in other types of ageing cabinets with standard shelves.
Also on display is our manual cutting press, EP 08, for fast, easy and ergonomic production of flawless rubber and plastic test specimens by punching.
Elastocon also performs contract testing in our testing laboratory. 15 testing methods for rubber are accredited by Swedac. Stress relaxation in compression and elongation, as well as compression set at ambient or elevated temperatures, as well as in low temperatures, are some of these testing methods.
Welcome to meet Elastocon at the K 2022 in hall 11/G17!
