Bio-Extreme™ High Temperature Oven Lubricants

NSF H1, H2

Bio-Extreme™ High Temperature Oven Lubricants are unique biobased food grade1 lubricants fortified with synthetic food grade white graphite (note).  This synthetic white graphite will lubricate at extreme high temperatures up to and over 1000°C with intermittent lubrication up to 2000°C and will provide a cleaner lubricating solid film (off-white to white) after the base oils cleanly dissipates. The products are formulated in different viscosities to provide proper penetration and then lubricate with the solid film into links, pins and rollers of different size chains. These (Biopreferredsm,) products are free of Volatile Organic Compounds (VOCs) and provide an auto ignition temperature (ASTM D-659) of over 371°C.  In addition, the products provide improved extreme pressure and lubricity after black graphite, Teflon, and molybdenum disulfide lose their lubrication between 400°C and 500°C. At the lower temperatures (below the flash points) these Bio-Extreme High Temperature Oven Lubricants do not dissipate, but leave a soft semi-solid to solid film on the lubricated surface of the links, pins and rollers. (See proper directions for using Bio-Extreme High Temperature Oven Lubricants.)


– Roller chains on oven conveyors– Lithographic chains, beverage can lines
– Tenter frames in textile plants– Kiln car wheel bearing/refractory plants
– Paint lines, drying ovens– Sealed for life units
– Kiln support rollers, cement plants– Bakery oven chains
– Automatic lubrication systems– Many others

Outstanding Advantages:

Exceptional High Temperature Stability – made from white graphite and biobased biodegradable base oils that reduce tendency to form hard carbon deposits in high temperature applications. (White semi-solid to solid film is soft and easy to keep clean with Food Grade cleaners and wire brushes.)

Cleanliness – helps to eliminate accumulation of hard carbon solids that create maintenance clean-up problems and downtime, cleans and lubricates chains already dirtied by inferior lubricants. 

Better Protection – reduces wear, rust, oxidation, and corrosion; extends equipment life, reduces maintenance costs. Bio-Extreme™ High Temperature Oven Lubricants are ENVIRONMENTALLY RESPONSIBLE products that are formulated from renewable agricultural plant resources.  We believe Earth’s environmental future rests in the use of renewable materials.

1 Products are acceptable as lubricants with incidental food contact (H1) for use in and around food processing areas. Such compounds may be used on food processing equipment as a protective anti-rust film, as a release agent on gaskets or seals of tank closures, and as a lubricant for machine parts and equipment in locations in which there is a potential exposure of the lubricated part to food.
