Stress relaxation ovens and boxes

Elastocon offers cell ovens specially designed for stress relaxation tests of rubber. This means that the inner height of the cells are adapted to fit our relaxation rigs to achieve as good thermal contact as possible with the bottom of the cell.

The oven also has an intergrated draught hood that eliminates the changes in the force during the test due to temperature changes in the environment around the top part of the rigs. The hood is made of polycarbonate, and has a temperature control system (Peltier cooling system) capable of keeping the temperature within ± 0,25 °C.

We can also offer two types of temperature boxes, for room temperature and below.

Cell oven EB 21 for stress relaxation tests of rubber

The EB 21 cell oven for relaxation tests has 4 cells with individual temperatures and individual control of the air exchange rate for each cell. Temperature range +40 °C to +200 °C (HT-version up to +300 °C).

The EB 22 cell oven for stress relaxation tests of rubber

The EB 22 cell oven for stress relaxation has 6 cells with individual temperatures and individual control of the air exchange rate for each cell. Temperature range +40 °C to +200 °C (HT-version up to +300 °C).

Cell oven EB 38 for stress relaxation tests of rubber

The EB 38 high temperature cell oven for relaxation tests has 4 cells with individual temperatures and individual control of the air exchange rate for each cell. The temperature range is +40 °C to +350 °C.

Cell oven EB 39 for stress relaxation tests of rubber according to ASTM D6147

The EB 39 cell oven for stress relaxation tests of rubber according to ASTM D6147 has 6 cells with individual temperatures and individual control of the air exchange rate for each cell. Temperature range +40 °C to +200 °C (HT-version up to +300 °C).

Cell oven EB 21 LTHTP for stress relaxation tests of rubber

The EB 21 LTHTP cell oven for relaxation tests of rubber has 4 cells with individual control of temperatures and air exchange rate. EB 21 LTHTP can be programmed for temperature cycling between approximately +20 °C to +300 °C, according to ISO 3384-1 method A and B, as well as ISO 6914 method A.

Cell oven EB 17 for cycling relaxation tests

The EB 17 cell oven for relaxation tests with 6 cells with the same temperature and cycling from -70 °C up to +245 °C, according to ISO 3384-1, ISO 3384-2 and ISO 6914 method A.

Room temperature box EB 02.08

The EB 02.08 room temperature box is used for stress relaxation testing of rubber in room temperature to avoid variation in the load curve caused by temperature variation in the laboratory.

Low temperature box EB 02.25

The EB 02.25 low temperature box is almost the same as EB 02.08, except that it is equipped with water cooling by tap water. It is used for stress relaxation testing of rubber in room temperature to avoid variation in the load curve caused by temperature variation in the laboratory.
