FAIRFAX, Va. — ExxonMobil has announced that it has received a U.S. patent relating to the manufacture of grease used in low-noise applications, such as HVAC equipment. The low-noise manufacturing process has been installed at the company's Olathe, Kan., 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. Tim Nadasdi, senior research chemist, ExxonMobil Research & Engineering.

Polyrex EM's applications include electric motors used in noise sensitive applications such as appliances, including HVAC units.
