More than 50 years of technological advances have helped us keep up with ethylene propylene diene (EPDM) rubber development.
Technology and investment milestones
|1961||Vistalon™ EPDM rubber is born||First commercially manufactured ethylene-propylene elastomer at the plant in Baton Rouge, Louisiana. Quickly found acceptance in high voltage electrical applications because it did not degrade over time, offering long service-life.|
|1966||Dedicated U.S. capacity||Butyl capacity in Baton Rouge converted to EPDM rubber production.|
|1972||New plant in Europe||Construction of new EPDM rubber plant in Notre Dame de Gravenchon, France.|
|EPDM rubber cross-linked within a PP matrix to produce Santoprene TPV, another technological innovation that has become renowned for its proven performance.|
|1989||Tailored molecular weight||First commercial grades of EPDM rubber manufactured using proprietary tailored molecular weight distribution technology were introduced for molded and extruded goods.|
|Late 1990s||Metallocene technology||Metallocene catalyst technology for development of new Vistalon EPDM grades|
|2000s||Broadest EPDM rubber portfolio||During the 2000s advanced technology leads to ExxonMobil Chemical offering one of the broadest portfolios of EPDM and other polyolefin elastomers in the world with Z-N and metallocene catalyst technologies complementing each other.|
|2003||New U.S. plant||New plant added in Baton Rouge, using metallocene catalyst technology, provides greater control of the molecular structure, giving more uniform molecules.|
|2011||50th anniversary||Celebrating 50 years of Vistalon EPDM, ExxonMobil Chemical is set to maintain its position among market leaders through continued investment in capacity, new grades, and technical and application support.
New grades that use the attributes of metallocene catalyst deliver improved compression set at low and high temperatures for molded and extruded applications.
|2012||Vistalon EPDM rubber production increase||50kt/year increased production capacity of Vistalon EPDM in our U.S. metallocene plant.|
|2014||Vistalon EPDM rubber capacity increase||Project for a new plant in Al-Jubail, Saudi Arabia which will include a new Vistalon EDPM unit, is at an advanced stage and is expected to be completed in 2015.|
