Newly Patented Low Noise Manufacturing Process Installed

at Olathe, Kansas, Plant to Produce Exxon Polyrex EM Grease

ExxonMobil today announced that it has received a U.S. patent relating to the manufacture of grease used in low noise applications. The low noise manufacturing process has been installed at the company's Olathe, Kansas, grease plant for the manufacture of the company's Exxon Polyrex EM grease.

"The installation of our newly patented process for the manufacture of Polyrex EM grease further underscores our commitment to the development and use of innovative technology," said Elizabeth Bennett, grease marketing manager -- North America, ExxonMobil Lubricants & Specialties.

"Since grease contribution to bearing noise is unacceptable in many electric motor applications, the advanced thickener formulation and our newly patented manufacturing techniques associated with Polyrex EM provide the consistent low noise performance desired in noise sensitive applications," said Dr. Nadasdi, senior research chemist, ExxonMobil Research & Engineering.

Polyrex EM's applications include electric motors used in noise sensitive applications such as dishwashers and blenders, as well as room air conditioners for hotel rooms.

"The effort that produced this technology is the result of the combined expertise of the heritage Exxon and Mobil lubricants companies," said Bennett. "More than 130 years of experience in lubrication technology, manufacturing and customer satisfaction were drivers in developing this new manufacturing process."

ExxonMobil markets lubricants in nearly 200 countries and territories around the world under the Esso, Exxon and Mobil brands.
