Fomblin® ZNF Grease


Product Overview

Fomblin® ZNF (now known as Klübertemp GR ZNF) is a homogenous white grease having good surface adhesion and wear resistance properties.

Fomblin® ZNF grease has extremely low vapor pressure and is ideal under vacuum in a wide temperature range of – 60˚C to 220˚C


A few of the critical uses of Fomblin® greases include:

Mechanical components operating under vacuum.

Mechanical parts in contact with aggressive chemicals or oxygen.

Nuclear industry lubricants

Instrument lubricants

Lifetime sealed, maintenance-free bearings

Bearings exposed to high temperatures, moisture and aggressive chemicals
