Effect of high temperature on elastomer strength

The strength of an elastomer measured at room temperature can be very different compared with its strength when measured at hightemperatures which can be typical of operating conditions. As a general rule, when elastomers get hotter their strength is reduced. By using advanced measuring techniques, the strength of elastomer materials at different temperatures can be measured. This information can then beused in finite element analysis (FEA) to determine whether a sealing material is suitable for use in high temperature conditions.

The graph shows diagrammatically how the strength of an elastomer is reduced with increasing temperature. By understanding these effects of temperature, our design engineers can confidently predict the performance of seals in the most demanding applications.

A high temperature, steam resistant, EPDM elastomer material designed for geothermal applications including pumps, valves, turbines, drilling tools and equipment. In addition to geothermal applications chosen materials may be used in steam applications for enhanced oil recovery and general purpose high temperature hot water and steam applications.

We offer an EPDM sealing material which performes at a maximum temperature rating in anaerobic steam up to +288°C, and may be used in short durations up to +315°C (600°F) in steam. This performance greatly exceeds standard EPDM materials.

Additionally, we provide a broad range of FFKM, resitant both to high percentage chemicals saturation (including methanol and sour gas), and extremely high temperature to +325°C.

Understanding the demanding challenges in the aerospace and oil & gas exploration and extraction industry, we offer the most technically advanced range of elastomer materials to meet the needs of sealing applications operating in the most severe conditions.
