EPDM rubber building products were developed in the late 1950's, specifically for the use in the construction industry of Middle East. The climate in the Middle East required a construction product that could withstand large temperature fluctuations. The product had to be flexible and remain stable at temperatures between -45 and +120° C. EPDM rubber turned out to be a very suitable product for this market .
