Ageing Ovens for precision ageing of rubber and plastic materials Cell Ageing Ovens with four or six cells Elastocon presents our latest generation of cell ovens for the precision ageing of polymer materials. We have produced and developed cell ovens and ageing cabinets since 1987. Benefitting from this long experience our ovens represent a major step forward in the design of such instruments. Manufactured in 4 or 6 cell configurations, the ovens are available with either single temperature controller or multiple (individual) cell controllers. • Improved insulation for lower energy consumption. • Lower surface temperature. • Settings are done on a colour touch screen. • Micro PLC control. • Resettable countdown timer for each cell. • Individual cell identifier – “Test name”. • Alarm history. The cell oven EB 20 equipped with 6 cells, each with individual temperatures. – cell oven, 4 cells one temperature for all cells, +40 to +200 °C – cell oven, 4 cells individual temperature for each cell, +40 to +200 °C – cell oven, 4 cells individual temperature for each cell, +40 to +300 °C – cell oven, 6 cells individual temperature for each cell, +40 to +200 °C – cell oven, 6 cells individual temperature for each cell, +40 to +300 °C All ageing ovens have a touch screen control utilising a micro PLC. Sample Holder – one holder per cell is included with the cell ovens. Elastocon AB • Tvinnargatan 25 • SE-507 30 Brämhult • Sweden Phone: +4633-22 56 3

Cabinet Ageing Ovens Cabinet Ovens with excellent temperature stability and distribution achieved by using an inner chamber with a controlled air flow. The ovens can be supplied in two sizes, with 60 or 120 l useful volume (EB 04-II and EB 10-II). Cabinet Oven EB 04-II with air supply that requires external air and flow meter that can be set between 3 to 20 changes per hour. These ovens are ideal for ageing finished products and large test pieces which are unsuitable for cell ovens. Both shelves and rods are supplied with these ovens for accommodating most types of samples. The settings are...

Cabinet Ageing Ovens All Elastocon ageing ovens have two temperature instruments, one for controlling the temperature and one for indicating the temperature close to the samples. EB 26 – an ageing oven with a carousel inside. Simple and fast mounting of the samples on the carousel which rotates inside the chamber during ageing. This oven is based on our EB 12-II oven and has a factory fixed air exchange rate of either 7 or 14 changes/hour. This oven meets the requirements in ISO 188 method B2. EB 27 – an ageing oven with high air exchange rate. It has 2 flow meters to cover the exchange...

The insert has three test tubes for testing according to ASTM D865 Heat Ageing and ASTM D471 Testing in liquids, and fits EB 19 and EB 20. The glass tubes can be supplied with a grounded joint for a stopper or for a water cooler. The glass tube system is also very suitable for testing in liquids according to ISO 1817. The images show the three configurations. 1. ASTM D865 Heat ageing 2. ASTM D471 Liquids with air cooler 3. ASTM D471 Liquids with water cooler Accessories for the Elastocon Cell Ovens Stand EB 01.01, stand to support the sample holder while mounting test pieces for ageing....

Information about ageing of polymers Durability testing What to remember about the ageing process The durability of polymer materials is affected by a number of environmental factors in combination with the mechanical stresses that are caused by the use of the product itself. In all ageing processes it is especially important to keep a constant temperature and in certain cases a constant relative humidity in air. This is because the speed of a chemical reaction is roughly doubled for a temperature increase of 10 °C – and ageing is in most cases a chemical reaction. Normally, the highest...
